0:00Welcome back to the Barbell Medicine Podcast, where we bring modern medicine to strength conditioning and strength conditioning to modern medicine. I'm your host, Dr. Jordan Feigenbaum. And on today's podcast, we have a very special guest, Dr. Sohi Carpenter. She's an evidence-based fitness coach and author based in Los Angeles. She is a friend of the show. She's been on the show before. And I'm going to just list off her CV so you can be as impressed as I am. She has a bachelor's degree in human biology from Stanford. There's a master's degree in psychology from Arizona State. And since we previously had her on the podcast in the spring of 2021, she's obtained her PhD in sports science from the Auckland University of Technology.

0:37It is my pleasure to welcome back Dr. Carpenter to the Barbell Medicine Podcast, where today we'll cover the research she did during her PhD program and her long-term experience with training her mom. Zohee, Dr. Carpenter, what's going on? That's me, I guess. I didn't realize it had been that many years since my last appearance. Honestly, it doesn't feel like that long ago. Yeah, I think you came to our New York seminar, so I think that like— Yeah. Even that was, what was that like two years ago? Yeah. Time flight. Yeah. That's, that's wild. Yeah. Yep. So we'll just do this quarterly. We'll have a quadrennial between your appearances just to catch up on life.

1:12Yeah. But I think the last time I was on, I want to say I was still in the beginning stages of my PhD. And then I've obviously since gone to finish, start and finish data collection and then finish writing my thesis and all that stuff. So, and then we moved. Yeah. Moved. We're still in California, but moved from LA out to orange County. It's still easier to say we're in LA because we're like an hour away, whatever. But now we've got a house. Yeah. And you've been a speaker at many international conferences. You're like an Adidas ambassador. It's been really fun. Yeah. So besides killing it, anything else going on?

1:48I mean, there's lots of things. I don't even know where to. Yeah, lots of things. But how much do you want to know? I wish I had you. We got some projects. Some of them we're not ready to talk about yet, but they'll come to light soon. But basically, I'm still doing the fitness career thing. I still love what I do. Yeah. She's an excellent follow on all social platforms. I'll also link to our previous podcast if you want to get the origin story. But we'll hop right in. I was excited. I saw your paper that you obviously you'd link to and then pulled the whole paper. So how did you end up picking this topic?

2:24We'll cover the details about it. But, you know, it's on circuit training versus traditional resistance training. So how did you end up picking this topic? Was it chosen for you or were you like? No. So this was OK. So specifically, it's high intensity circuit training, high intensity. And that part is really important because, you know, my my thesis is on resistance training and women specifically. And I found that when you talk about circuit training amongst the general population, most women, um, when they're like, oh, I do, you know, Barry's bootcamp or orange theory or, you know, popular.

2:59Exactly. Um, a lot of the circuit training that they do, I found, um, that they don't actually push their sets as hard as they could from a proximity to failure standpoint. And so I was thinking, okay, when you actually match the effort, um, how, what, what are we going to, what are the results between, you know, strength, body comp, all that stuff, hypertrophy, blah, blah, blah in women. And that question was something that I actually want to investigate since well before my PhD. This is back when like years ago, I was living in San Diego, still like 2017, 2018 timeframe, because obviously from all my years of working with women, we found that time is a very common barrier to regular exercise.

3:40And I think a lot of people can relate to this. And of course we know that circuit training is more time efficient. You'd get your workout done a lot faster. So I thought, okay, well, personally, I have a preference for the traditional strength training workouts where you do one set at a time and you rest for longer in between sets. I don't usually enjoy the circuit nature of the back-to-back exercises with short rest periods, but a lot of women do, and that's fine. But we didn't really have a lot of research at the time to say, well, based on these two popular modalities, if you want to have these results, this is the modality you should employ.

4:17If you want to have these other results, this is the other modality you should employ. And so I was thinking, okay, why don't we, how cool would it be if I actually set up a study to investigate exactly that? So that's kind of how it happened. And then I started my PhD. And then of course you think you're like, oh, I have this one question. I'm going to dive right in. No, it took like three, four years before I was even able to start data collection for that and setting up the study design and getting that ethics approved and everything took like a year, you know, everything takes so much longer.

4:46So, uh, you know, thankfully I was able to collect the data, answer my question, uh, which was really cool. And even publishing a paper is so much work, so much work. Uh, so was obviously very excited. I got the news about that publication, um, that paper being accepted for publication this past April or so. Um, I think it was actually the same. I think it was the same morning. I was defending my thesis, actually. So it was a pretty exciting day. Yeah. Like that morning I got the news and then like a few hours later I defended my thesis successfully, blah, blah, blah. So it was a big day. And then, and then it was like a couple of months later it was actually published, but the timeline for that and the amount of work involved, honestly, it's made me have so much more respect for, for researchers who publish all the time, but also you become a lot more understanding of study design limitations and things like that when you're like, oh, well, now it makes sense why you couldn't do X, Y, Z because logistically it's actually so much harder.

5:45Or if you were to try to implement, make these, enforce these requirements on your participants, you would have had one third of the people finishing the study, you know, things like that. So it was a big learning experience, but yeah, the biggest finding was one, unsurprisingly, the high intensity circuit training. So they did the same exercises, the same sets and reps in both conditions. Don't don't give away the plot. We got to. Yeah. Oh, OK. OK. Don't go to the findings. OK. Yes. It's published. It's very cool. I think it's great. It's great news for women all around. Yeah. No, I was. Yeah.

6:17When I read the title, I go, ooh, this is interesting, mainly because and to your point earlier, circuit training is popular, not not only just commercially, but also, again, to your point for people to save time. They're like, oh, well, I'll just minimize my rest periods. I'll do these exercises. Yes. And it's not that that's problematic on its face, but because that layout, that structure tends to result in a number of things. One, people use lighter weights. Two, people tend to stay further away from failure. Three, exercise selection often varies, you know, and so it just becomes a much different comparator to traditional resistance training.

6:53So I was really impressed with how you laid this out. You effectively matched everything. Yes. Except for people doing it back to back. Or were they resting? So yeah, the title of the paper, and I've linked it in the show notes below, it's open. You can get it on ResearchGate. You can read the whole thing. It's titled Effects of High Intensity Circuit versus Traditional Strength Training on Physiological Responses in Trained Women. It's in the European Journal of Sports Science. I see some friends on there as well. Got Dr. Eric Helms. We got Rachel. Cool guy, yeah. How do you say her last name?

7:23Penteker. Okay, it's exactly how it looks. Yeah, she's amazing, yeah. Yeah, star-studded lineup there. And so, yeah, as you mentioned, you took women. These are trained women. And you randomize them into two groups. They were going to do circuit training or traditional resistance training three times a week, eight weeks. They did the same exact exercises. They used the same relative load. So it wasn't like, oh, if you're doing circuit training, you're doing this way lighter. No, it was all relative to their strength and how close to failure they were pushing. And yeah, so lifting the same amount of weight, the same reps in reserve, uh, by and large in an 18 to 15 rep or eight to 15 rep range, uh, except for, yeah, one did them as a circuit and the other did them traditionally.

8:03And traditionally in this case, okay, you do a set rest three minutes. Correct. And yeah, so we really tried to control for as many variables as we realistically could. Um, and that was, that was the outcome. Yes. That's what we came up with. So just on it before you even did went into data collection and got the data to look at, was your hypothesis like, look, if they're lifting the same weights for about the same training load, like reps and total sets and stuff, just the rest periods between the specific exercises are different. Was your hypothesis like, we think it's going to be about the same?

8:38I want to say I have to go back and read the paper. It's been so long since I wrote the paper. And now that I know the results, it's like, of course, you look back and you're like, oh, of course. of course you predicted i want to say because there was there was at least one similar study done in men where it was high intensity circuit training versus traditional strength training and they did find that strength of body comp was similar between the groups so i want to say we were we predicted at least for like at least for the body comp similar uh changes but i'm not sure i have to look back i i think the strength gains we predicted maybe this traditional strength community group might have better strength gains.

9:13Yeah. Some one or the other. But I mean, we weren't completely surprised. Realistically. Realistically. Point. Having the benefit of recently rereading your paper, I believe, and again, when you guys are listening to this, go and read the paper, which I encourage you to do because it's well written. And there's a lot of background information that would, even if you're not particularly interested in this specific question, all of the background information on training and predicted outcomes is super useful as a health and fitness professional. But I believe that the thing was like, well, look, we think if we're lifting the same load, same relative, you know, same training load, proximity failure, strength gains, hyperfibration should be similar.

9:49But maybe there's a metabolic or like fat burn advantage potentially to the circuit training because you're like – Your heart rate's – Yeah. Heart rate's higher. Yeah. Working way higher. Yeah. So, okay. Here's my first question before we, you know, kind of give away some of the results. We'll cover them in more detail. Yeah. One thing I didn't see in there, and this might just be because I'm getting older and just I bypassed it. What was the difference in total time spent training per session? Yeah. So I think we maybe alluded to it a couple of times. The reason why we were not able to run statistical analyses on that was that we weren't meticulously tracking their exact duration, which obviously in hindsight, you're like, why do I think of doing that?

10:32So what we could say was approximately the high intensity circuit training group were finished with their session in approximately like 50 to 55 minutes from including the warmup, like dynamic warmup, all that stuff from beginning to end. Whereas the traditional strength training group took closer to like 70, 75 minutes. And you're like, okay, that's only like 20, 25 minutes. That adds up a lot throughout the week. That's a lot of time. That's a big difference. And so to me, that was pretty significant. So, and of course, too, like even 50 minutes, you can do a shorter circuit training workout.

11:08You can do 30 minutes and get a lot done still. Totally. But for us with, yeah. Like factoring in, okay, you got to go to a gym. Theoretically, if somebody did have to do that, change clothes, drive home, travel to whatever, those minutes add up. It can be the difference maker between, oh, this person can participate and adhere to a particular, you know, exercise program versus. Yeah, they're not even gonna try. I feel like like I got 80 minutes plus travel time plus right, plus, right. And how many people think that in their heads, they're like, Oh, I don't have a full hour or whatever to dedicate.

11:38I'm not even gonna bother trying. But also, yeah. And I think obviously, too, with the exercise, I think that all the time, and I have to remind myself, any like 20 minutes is still worth doing 30 minutes is still worth doing. Yeah. Yeah. And so that's kind of a message that I'll try to remind people of all the time. But But, you know, if you look at the exercise selection, am I allowed to talk about that right now? So we did use, obviously, you know, the findings should be able to be applied to different program designs, like different exercise selection. But, of course, with the caveat that exercise selection and exercise order does matter.

12:14And if you see, like, the first circuit, the first three exercise circuit was like press, flat dumbbell bench press, and trap bar deadlift. And we really tried to, first we did like, you know, upper, lower, lower, upper, alternating lower, upper exercises, which was great. And then we also tried to ensure that there was like minimal overlap between the muscles worked in back-to-back exercises as much as possible, which I think did make a difference in terms of the performance that people, you know, their performance in the working sets throughout the training design. So I would say, you know, if you have a good trainer or if you know how to write a sound training program with the right exercise order, I think the results can be applicable to like, let's say you only had several pairs of dumbbells.

13:01You can swap them out for dumbbell variations and probably get similar results. Again, as long as you're pushing close to failure. That's what I think. Yeah, that was one of the probably most germane methodology things that you guys did is that really what they did for the high-intensity circuit training group were two basically tri-sets or giant sets, the three exercises you would do back to back to back. But there was minimal overlap in one exercise to the next. So you went from leg press to dumbbell bench. And so we would classically call that like an alternate peripheral type superset, for example.

13:34And then you did trap bar deadlifts after the dumbbell bench, which again, another alternate peripheral type superset. Now, comparatively, you could have done all upper together. So like dumbbell bench, you know, another shoulder press, theoretically, if you were doing something like that, and then chest flies. You didn't include those exercises in your thing. But if you did agonist, agonist, agonist, that would be a completely different setup than this alternate peripheral kind of setup. Yeah. And we, you know, we obviously intentionally avoided that. I think the way that we did it was the right way to do things.

14:09And I think if your goal is to, so to speak, optimize strength and body comp and all those variables, it probably would be beneficial in general to alternate muscle groups as much as you can. Yeah, when I program for folks and I'm doing like a full body workout or even just a body like region, like an upper lower split, I tend to program either agonist, antagonist or alternate peripheral such that if somebody did want a superset, they'd have that option with minimal, quote, interference between the exercises. And this is my understanding of it, and I'd like to get you to comment on it. But when you prepare exercises like that, or if you're going to do them back-to-back, like a superset or back-to-back-to-back, like you guys did here, triset, something like that, giant set, the whole goal is to preserve not only training load, so how much weight you're actually lifting, your relative training load, but also volume, like how many reps you're doing per set.

15:02And so with this type of setup, you don't really compromise that much compared to like I did dumbbell bench press and then I did dumbbell overhead press and then I did chest flies. It's like, well, yeah, if you do this back to back to back with no rest periods, you would expect the volume to drop off. You'd expect the person to be able to lift less weight. And you would predict, especially based on your findings, which we will get to, I swear, you would predict the people to have gain less strength, gain less muscle mass, whatever would be compromised because of the training load being less compared to something like this.

15:31Is that correct? Yeah. Yeah. Yeah, yeah, yeah. And actually I would say from, you know, obviously I was there for practically every single training session for all the participants. Oh, they were supervised. You were there the whole time. Oh, every session. It was either, there were like maybe three sessions or so I wasn't there for, but Rachel was there. And, you know, we're both, we both have our CSES. We're both experienced. So, which I think is a very important component because I've, I've heard that not all research studies are properly supervised with qualified trainers, which I think is a huge limitation because.

16:02how do you know they're right lifting with good form how do you know they're lifting with the proper range of motion how do you know that they're pushing close to failure like they're supposed to and and actually a lot of times what was really surprising with almost every single participant even though they claim to be trained they all were surprised at how much further away from failure they were lifting in the beginning versus how much more i had them push and they'd all be like i had no idea i could push that much yeah yeah that was really interesting the sohi effect. Yeah. And I'm like, well, this is, this is how your sets should feel.

16:34And they're like, I've never lifted before. And a lot of it was, I'm not confident of my form. So I don't want to push myself in case I get hurt. That was a very common, um, you know, the remark that they would make, which I found very, very interesting. So then it made me wonder, okay, how many of these women who train on their own or don't have a, you know, good trainer with them, they think they're pushing close to failure, but they're actually like, you know, four or five reps shy every set all the time. So that was very interesting. The coolest part about that being supervised, especially in this case by qualified coaches, experienced coaches, is that whatever you see the programming on in the paper is legitimately, you know, at least to the best of your ability, what the people did compared to if it was unsupervised, like, yeah, just go do this program.

17:17On the one hand, there's some maybe more real world validity to that. You're like, all right, look, if I write a program for somebody and this is how they're going to execute it on average, well, there's, you know, some benefit to that. But the downside is that we don't really know what they were doing. And so if you get a spurious result or series of results, it's like, okay, well, that is an opportunity for error for sure. Yeah. Yeah. And so, yeah, it was really important for us to make sure that every single set we watched and we would actually dictate what loads they would lift. They wouldn't tell us, we would tell them obviously based on how they told us they were feeling that day, how their warmup sets felt and how quickly the reps were moving, things like that.

17:52But, you know, I've been training clients for long enough now that I can basically eyeball okay this is what you're gonna do today and basically by rep one i can already tell you're probably gonna lift this many reps for the set yeah um so that was really cool uh for me to do that and but yeah it was it was very very interesting the number of people who genuinely they they they didn't know what pushing to failure felt like um but also i think there was a bit of a you know like probably a bit of a trainer effect where having me there they're like oh if you tell me i can do it then i know i can do it i could do it yeah so that was that was really cool too.

18:24Yeah. Yeah. Nice. The, she has a very mature coaching eye, which can be, can be useful. Okay. So we bury the lead enough here. What were the results? You got, again, one group doing for eight weeks, they're doing circuit training, another group doing this, lifting the same relative amount of weight, the same, about the same reps and such and proximity to failure, but with traditional rest periods, what were the results that you guys found? uh okay so we measure strength using three at max testing for all six exercises the six exercises were uh as i mentioned the first three were leg press flat dumbbell bench press trap bar deadlift then we had lat pull down a barbell hip thrust and a standing dumbbell shoulder press and so we did three at max testing for all participants before and after and we actually found that both groups had similar strength gains in three at max across all the exercises as well as uh similar gains in muscle after eight weeks.

19:19So that was really cool finding. I thought that was very encouraging because if anything that allows us to say, based on the findings, I really think that your personal preferences and your time constraints, as well as maybe like logistics of your gym setup, things like that should be the biggest factors to determine what type of training is best suited for you. And as well, another one thing we mentioned was, of course, we didn't study this directly, but maybe you can even employ a combination of where you maybe start off like the first two or three exercises, traditional strength training style, and then you end your workout with a circuit.

19:55You can kind of combine them both if you wanted to have a bit more variety, which, you know, that sounds more interesting to me personally. But basically the point is like, you know, you have options as long as we mentioned it still only times throughout the paper, as long as you're pushing close to technical failure, the results will be similar. Yeah. One of the things that I've been saying a lot recently to try to, you know, if there's a central paradigm with respect to exercise prescription is that we want people to do as much exercise as they can with the two limiters on that being logistics.

20:30One, so how much time do you have, you know, resources you have access to? And then two, what's your physiological tolerance for exercise? Right. That was – So in this particular case, you've effectively determined, this is my understanding, that you could pick either. Yes. So for a person that's got less time, circuits, supersets, triset can be an option if you pay attention to exercise order, if you pay attention to the relative load being lifted and approximative failure, things you would normally pay attention to anyway during traditional sets. Or if you have more time and you prefer a different way, you could do that too.

21:03There's not like a – the one that rules them all, not a particular advantage outside of preferences and in this case maybe how much time you're spending. Right, right, right. So like if, for example, I were to attend a – I don't know, an F45 class and I was – it was like, okay, it's time efficient, blah, blah, blah. It's great. I would try to make sure personally, okay, am I actually lifting hard enough with each set? Because especially – Is the weight heavy enough? Yes. Yes. And the nature of – we know in the nature of group workout classes, you're not going to be supervised as closely with every single set, every single repetition.

21:32So it's kind of up to you to build that self-awareness and accountability to be like, okay, I can definitely do more, but also while keeping yourself safe and all that stuff. So there's that too. I actually had thought about doing like a mock call where I was like the CEO or regional director from F45. And I was like, ring, ring, Dr. Carpenter. Hey, look, we're trying to optimize our subscribers, our members' results. What suggestions would you have for improving our exercise program and our exercise structure? And so the problem obviously is that you don't really know what's going on inside each box, each F45 place.

22:09But my understanding and the way I see it anyway is that there's not a ton of thought with exercise pairing. and then there's not – I don't feel a lot of assurance about like, okay, we're using heavy enough weight to reach failure or close to failure within maybe that 8 to 15 rep range like you guys used. Or even just we can liberalize that and say, all right, somewhere between 5 and 20 reps, we want to get you within a couple reps of failure. It more seems like we've got to station for a minute. Do as many reps as you can and just try to sweat a little bit. Yeah. so that is my i've been to i think i want to say two classes at 45 classes before and obviously this is not an op on at 45 by any means it's also been years since i've attended a class the last time i went i think of it i think they were pairing uh bent over rows with band assisted chin-ups yeah and anyone right away right away uh obviously you're working like basically same muscle groups second of all your grip is going to be totally fried to the point where i remember for the chin-ups by the end so we you do like multiple sets right by the end i I think my last couple of sets, I was using like the fattest band because I'm like, I don't have the grip strength to do this anymore.

23:16And you have me doing this for like 40, 45 seconds straight. That's a lot of reps of band assisted chin ups. So I remember being a little bit taken back by that and a little bit confused by the program design there. Now, of course, maybe things have improved since then in terms of exercise. I don't really know. I still think that from a exercise enjoyment and social support standpoint, those types of classes can be fantastic. Cause I know, especially for a lot of women, they, you know, my mom, for example, which I know we'll talk about her in a little bit. Um, she's, she'll exercise in a social setting.

23:49She will not do it by herself. So for someone like her, those kinds of classes are fantastic. Yeah. So I think they're great. You'd prefer the exercise order to be a little different. And we tweak a couple of things, uh, and then tweak small changes to make big improvements. Totally. I think. Yeah. Yeah. In your example, it's like, all right, look, if your grip is fried, Right. So you can't technically do the second exercise to the ability that your lats, your upper back, all this sort of stuff can. And so those muscles, they, yeah, they're receiving less training stimulus. And so if you had to predict a long-term outcome, you say, well, I predict that my strength is going to be less on pull-ups and with that sort of setup.

24:24My grip strength, maybe, I guess, strength endurance might be higher, but you're ultimately compromised more when you pair the same muscles back to back. Right. But yeah, here's the wrinkle I'll throw in there to get your take on it before we move on to training, training your parents. Do we think any of that is like from a enjoyment is the wrong word, but maybe like a like a marketing based approach where it's like, look, you come to our workout class and you're going to work. Yeah. And you're oh, look, you can only do one rep at the end because you were so fried. And yeah, because I would predict these things.

Read the full transcript

24:59Yes. Closer to failure, more soreness potentially. And so you leave the class, you're like, I got a good workout. And it's like, yeah, I feel obliterated. Yeah. I think that's really tricky too, because I do think that people expect to feel that way at the end of those types of workouts. But we know that if, if I were training someone who was an actual beginner to lifting, we know that's not the smartest approach. It's probably best to have them do like a shorter session, uh, maybe like 30 minutes, have them rest for longer, um, go slower, pay attention to their form, have them do like one or two working sets of every exercise and then have them leave feeling really good.

25:34And so we can hopefully mitigate some muscle soreness the next couple of days. But I think when that happens, you run the risk of them being like, Oh, exactly. I don't feel anything that did nothing. I'm not going to go back. And so I do think while the, the approach that, you know, I described is probably the better approach from a long-term and, you know, smart trainer perspective, responsible perspective, is that, is it going to actually backfire in terms of getting them to come back? Because they don't understand. Yeah, because they'd hear them suffer or something like that. Yeah. They're like, oh, I don't feel obliterated.

26:05I'm not going to go back. But then of course, you have on the other side, maybe they're too sore the next few days and then they hate it. So there's also that. So I don't know. I think it's tricky, kind of balanced, like what's actually the right approach to do things versus what people think that they want because they're not always the same. Yeah. I think there's some opportunities for learning when, you know, people are warming up. You get to describe, Hey, here are the goals of the workout. Here's how you should feel. And you said, here's why we structured it this way. I mean, I assume look at 45, I assume is doing well financially.

26:33Other class, class. Yeah. Yeah. Like whatever, they have a sauce that's working from a adherence, reducing the churn rate, getting people to participate and come back standpoint. But like you probably make the program a little better. I feel pretty confident. I mean, I I've already, I've toyed with the idea and I'm very much right now firmly know but i'm like oh man if i could ever if i ever want to open my own gym i already know how i'd run it i'd probably make it uh like small group sessions they'd probably be mostly uh like traditional strength training uh base or at least you know starting out with traditional strength training maybe ending with a couple of uh intelligently programmed circuits things like that but it would be yeah it was it would all be about like okay if you're a beginner here's your maybe like your four-week beginner intro course that you're going to start with then after that you can then graduate to the intermediate advanced group.

27:19And then this is how we're going to do things. We're not doing things for time. We're doing things for, you know, rep. We're going to learn to embrace the rest periods, blah, blah, blah, blah, blah. So I've all thought about those things. Unfortunately, as I'm sure you probably know, running a in-person gym is extremely time consuming. Logistics can be really, really rough to work with. Profit margin is like almost non-existent. So lots of things to consider there, but I'm like, I like the idea of it. We need an AI hologram of Sohi. And it would just like, she can do that while you're busy. You can do everything.

27:51Yeah. Like, don't make it, don't make it. Honestly, I love, I love working with people in person. I find it extremely gratifying in a way that the online work will never measure up. We know this, the in-person relationships are so valuable, but at the same time, you know, really, and people who are in person, you know, full-time personal trainers at a gym will understand. Obviously, it's a huge sacrifice to make in terms of your time and energy. consumption. Yep. So I love training people in person, but I only have so many hours in a day and I'm like, Oh, gotta make a trade off somewhere. A hundred percent.

28:24All right. So that link to her paper is in the show notes below. And so I encourage you to take a read again, even if you're like, look, I understand that's all this now the background reading and stuff is, is excellent in the paper. So well done. Yeah. Thank you. And actually the one other point I want to mention, because when I posted about the study, of course we got some, well, Chris is like, well, you know, not a lot of us can do that exact circuit in our gym setting. It's not meant to be literal. No, because you know, I don't expect people to have access to a leg press and a flat dumbbell, like a bench press and a trap bar machine, like trap bar deadlift.

28:56Yeah. A trap bar, all three of them at the same time. Of course, if you're at a busy gym, you're not realistically, that's not going to happen. Jerk face. Yeah. You take it up all the equipment, but you can find similar alternatives where you can maybe maximize like space efficiency. Maybe you can find dumbbell turners for all of them. You know, those there's, always options and alternatives yeah to make things work for the leg press you could do some sort of squat pattern a goblet squat for what for example one yeah i mean whatever some sort of uh squat pattern type movement yeah or you can also add in uh unilateral exercises which we purposely didn't do because obviously for like through max testing it's a lot trickier to be like well she got four reps on this leg and two reps on this leg so what do we say so we kept it bilateral for everything but you could obviously swap in like reverse lunges step ups things like that if you wanted to.

29:41Yeah, agreed. When you see a squat pattern or a press pattern or row pattern or hinge pattern, you there are multiple subs within those categories. We predict they'd all work reasonably well for the same sort of health promotion, stuff like that. This podcast is brought to you by Biggs. At Barbell Medicine, we spend a lot of time talking about what it takes to build a body that can handle high level performance. But the recovery and health side is just as critical. Over the last six years, an incredible team of health care professionals did something that most people thought was impossible. They helped rebuild the body of legendary Olympian Lindsey Vonn after a series of devastating injuries.

30:14And now, she's actually headed back to the 2026 Winter Games in Milan, and she's ready to break records once again. This February, Lindsey's team and the entire USA medical team will be wearing figs, and you can rock their official uniform too. The new Team USA collection from Figs is engineered with Fiber X. It's their most durable fabric yet. It really is setting a new gold standard for high-level performance scrub wear because it's lightweight, it's breathable, and it's ultra resilient for those long shifts. And of course, the style comes in red, white, and blue. Now, if you want the gear that the medical team behind the world's best athletes are wearing, check out the limited edition Team USA collection.

30:48You get 15 % off your first order at wearfigs.com with code FIGSRX. That's wearfigs.com, code FIGSRX. All right. Let's shift gears a little bit. One thing I wanted to talk to you about for a long time now was your experience in training your mom. At the beginning of this year, I also like how your face lights up because the same thing happens to me. I started training my dad after his second knee replacement. And it's always been a goal to get my dad to start lifting regularly, which I think is pretty common amongst people who regularly exercise. So if you can tell us a little bit about your mom and what prompted her to get started with you.

31:25So my mom right now, she's 64 and she's actually been training on and off for probably over 10 years, but she's always had a trainer in some capacity, someone working with her. And so when eventually I want to say like six years ago, we ended up living in the same general area. Um, uh, actually I want to say like closer to four years ago was when we moved out to OC, which is where they also are in Orange County. And then, uh, you know, I immediately built a garage gym. And so she would come over and, uh, like I want want to say once or twice a week. And it was oftentimes my, I was the one prompting her because she's, she's not someone who inherently loves to exercise.

32:07She's not the type to go out and do a workout by herself, but if she has the accountability, she will, she will show up. Right. So every time she does any form of exercise, golfing, Pilates, lifting with me is always with someone else. Okay. Right. So that's something that I noticed very early on. I also noticed that she's not the type to enjoy pushing herself much on her own and um you know and i say this with the most love of my heart i don't she doesn't have the greatest body awareness in the gym so i'll have her let's say i'll have her do a set of goblet squats um we'll rest two minutes three minutes and i'll say okay do it again she goes what am i doing hey what what i do you know and then you know and then the next week i'll say okay this is your warm-up set here's your weight and she'd be like this is way too heavy and i'm like you did this last week as a warm-up and And she's like, oh, you know, so it's like you need she's someone who really needs someone there with her to be like, this is how the exercise looks.

33:02This is the way you're going to do. This is how many reps you're going to perform. Yeah. So she really needs a lot of that guidance. But she's great, at least with me, not with my dad, funnily enough. She's great at listening to me as a trainer. But then, you know, if it's my dad's trainer, she she's like, I'm not doing this. I don't want to do this anymore. You know how you know how it is with like family members can be like that sometimes. but um it was it was really fun because uh i wanted to keep it it was really important to me to make it a very positive experience for her and that meant uh at least for now those types of you know the f45 orange those classes would not be a good fit for her i think she'd feel too overwhelmed the music would probably be too loud the rest periods would be too short so i was like i have to cater this to her but also make the short sessions short enough that she is willing to actually show up in the first place so my first several sessions with her they were like 20 minutes long.

33:51They were very, very short. And I would do, yeah, I would do like two sets of maybe six exercises and I would like super set, you know, upper, lower, upper, lower, upper, lower. And then I'd be like, okay, that's done. And then she's like, oh, that's it. Oh, yay. I'm done. And then over time you slowly add on more, you slowly add on more, you make them a little bit, you know, tougher, you add the load and so on. And then over time she saw, oh, she, and then she would show up the next week and be like, oh, my golf game is getting really good. My golf swing is really strong and everyone's starting to notice.

34:19And then she gets more excited about it. And you say, yeah, that's because you're lifting weights and you're getting stronger here. And then she becomes more motivated to keep going. So it became a really positive feedback loop. So we've been we've been trained together on and off for a number of years now. It's been really fun. Yeah, no, that's a similar similar kind of experience with my dad, Leonard. He he does like exercising, but he would not do the type of exercise that I want him to do. Yeah. Which look full marks to him. Like you want to go to the gym. You want to lift some weights. You want to do some cardio or as he calls it, cardio's, which I don't know.

34:56That's great. Yeah. Hats off to you. But I, you know, in this particular case, he was coming off this knee replacement and he suffered a pretty significant loss of not only mobility, although now his pain was better, but in strength and such. And so that was his like motivation. And so, you know, admittedly for he's 73 now, admittedly, it's challenging to get a septuagenarian under the barbell to squat, for example, especially if they haven't been doing it their whole life. You know, so that's not something he would do. And I actually asked him because I was out of town for a bit. I was like, hey, would you like do the leg press?

35:31He's like, how do you use that? And I'm like, OK, so we need we need some guidance here. Yeah. Yeah. And so it sounds like her initial program was relatively shorter, less sets, less volume or whatever. And then as she not only got more familiar with the exercises, but also as her fitness improved, her training tolerance improved, you added more. So if her initial sessions were 20 minutes-ish, right, with lighter weights and whatever relatively, how long do her sessions last now? I mean, is she – They're – yeah, they're like 50 minutes, five zero minutes now, so almost an hour. And if you do that twice a week, that's a lot.

36:05that's a lot of lifting oh yeah that's really good and what's nice is that because it's obviously my private gym she plays the music that she wants when she's wrestling she does whatever she wants uh when my dad's here they turn on npr actually oh okay i don't know i didn't know what i expect like pink pony club but no no my parents are very they love the classical music and stuff so sometimes my dad will play opera i don't know and i'm like you know and sometimes i have to override like listen i can't do this because i'm also working out so i'm gonna change the music to something that i can lift to but i give them a lot of flexibility like for example when we're home uh and she's training on my garage gym between sets she likes to wander out to my garden and check on my plants yeah which is nice for your plants yeah i'm like that's great uh but and then i'll let you know when you have to come back in to do your next set you gotta call mom come back it's time to squat she's like in her she's got her gardening gloves on and she's like digging you know in the dirt and whatever but i think it's quite cute because she obviously wouldn't be able to do that in a, in a, in a different gym setting with a different trainer.

37:06Not a lot of gardens at the local 24 hour. Yeah. So I'm like, you know what, as long as you're doing your sets, I don't care what you do in between. Totally. Yeah. One of, one of the interesting things here that I want you to speak to is on like progression here. Um, we've, we've, we've gone through so much like trying to public facing, um, uh, publishing about what is really progressive overload. What is progressive? And the way we explain it is that as your fitness increases, whether it's measured by strength, whether it's measured by cardiorespiratory fitness, training tolerance, whatever, you'll have to do more to get the same type of training stress.

37:41You're really not trying to increase the training stress, but really just match it to your new level of fitness. Whereas on the other side of things, people are like, no, you just have to add weight every time you go to the gym or add a rep. Right, which is obviously an oversimplification. Because if we don't think that strength improves really reliably on a weekly basis, for example, then adding weight or adding a rep would really just be like, we'll just make it harder. And it's like, well, it should be the same level of hard. Because you're supposed to be getting fitter over time. Yeah, it's like chicken egg kind of situation.

38:08Is that what you use with her? Yes, but we're also talking about exercise progressions too, right? So if she's doing a incline pushup or a torso elevated pushup, which I like to do it on a squat rack as much as possible, obviously not realistic for everyone, especially if you're at a busy gym, but it's very easy to adjust the height of the barbell, right? you're like oh you're on this number hole then you're you lower over time um so for example if she's doing like three sets of eight at a given height like shoulder height barbell and it's obviously starting to get easy for her i would either add reps or i'm like okay let's lower the height of the bar that way um even even though when you log it you're like okay she's on whole so and so um the total load technically does increase because she's lifting more of her relative body weight uh it's technically technically still considered an exercise progression because you're making the exercise itself harder so i mean you can do this with almost every every movement pattern you can find regressions and progressions totally um but for example i probably would not have her do a barbell back squat per se big given her movement patterns and her level of body awareness but maybe i'll have her do a lever squat or i can have her do a leg press yes i can have her do a goblet squat those things i can have her do a unilateral like a braced dumbbell split squat.

39:24And maybe over time you progress that to a dumbbell in each hand doing reverse lunges. Yep. You know, there's always variations you can do like that. It's the same thing I've done with my, did my dad. Now, obviously you had some, uh, anatomical, uh, you know, limitations initially, but safety squat bar box squats and you're people like, why did you start there? And I'm like, well, I'm a power lifter and like old habits die hard. Like I want people to squat, but he could do it. And also him holding that was much easier than a, straight barbell yeah yeah but his range of motion was limited initially as well as his like awareness of kinesthetic awareness you know from right so you probably had him do like higher higher box squats yep got lower eventually didn't need the box anymore could squat to you know to depth and same thing on a debt on the deadlift initially it was from an elevated surface and then it was from the ground and so there are multiple multiple options and you know some sometimes it does add load like in the push-up example that you have uh sometimes it adds a stability component like going from an assisted split squat to a freestanding split squat of some version.

40:24And yeah, obviously you can add reps, you can add sets. But the whole point here of the progressions is that once their fitness is improved to a point where their current prescription is no longer challenging enough for them, you have to change something. But you don't make that change ahead of time. That's kind of the line in the sand I'm drawing. It's like, as you get stronger, the weight will go up. You don't add the weight necessarily to get stronger, if that makes sense. And I think people have a tough time with that. They're like, oh, I just have to add five pounds every single time. And I'm like, big if true.

40:55That would be incredible. Like, imagine if, imagine you put five pounds on your deadlift every single week. Well, why am I not deadlifted a thousand pounds? Right. Right. And then I think we do have a lot of people thinking that and then they get upset if they can't get strength every week. And I'm like, can you imagine how much you'd be lifting by the end of the year if you really were lifting that much more every single week, even if it was two and a half pounds every week, that would be incredible. Yeah. I have a shirt that I bought. It was an incorrect purchase. It was one of those things like a targeted ad and I was like, oh, cool.

41:24It was just a random like LSKD shirt or whatever. And on the back, it says 1 % better every day. I'm like, well, so then at the end of the year, 365. That's a big percentage. Yeah. Yeah. I don't know that that's reasonable. I get the message, but come on, guys. The idea of it is nice, but when you really do the math, you're like, that doesn't make sense. Yeah. So she's training with you every single time, approximately twice a week. Is that what you guys are doing? once or twice a week depends on her it actually depends on like both our availabilities okay and actually sometimes she does come to but now i also have a warehouse gym which is where i am now sometimes my parents will come here without me and they'll be like hey we're here now we're training and then it's always the same thing where my dad's like she didn't listen to me but she still did some stuff but i'm like i don't care as long as you're doing it yeah you're trying yeah the participation is you're showing up you're doing it um and obviously if they're traveling a lot more it's harder for them to be consistent but i'm like i don't mind those breaks here and there as long as you eventually get back to it yeah but yeah she's she's doing great what was what would you say like the biggest challenge that you faced with with uh training her and while you while you marinate on that just with my own with my dad the biggest challenge for him is almost holding him back a little bit because he's like he's like just add more weight and i'm like because his thing is like he's like i want to look like you i'm like well i don't know that that's in the cards just like i've taken some various specific steps to get here but hey uh he's like but if i lift more weight i'm gonna look like you i'm like that's oh anyway that's gonna challenge i think it was probably the opposite for my mom where she convinces herself that everything's too heavy for her even when she's more than capable you know as i mentioned earlier when she's she's done it as a warm-up set before the week prior and she's like oh this is really heavy and i'm like no this is a warm-up set it's a literal warm-up set and then you then of course you increase the load for the next second she wants to get to like there's no way i can do this and then she busts out eight pristine wraps and i'm like okay you did it so every it's kind of like every exercise feels a little bit like that but you know i've been training with her training her for long enough where i can't anticipate this and um you're not really dismissing their complaints per se but you know that they are telling themselves a false narrative yeah you had a redirect like look you might feel this but the reality yeah and we're not gonna do we're not i'm not gonna listen to you in this specific scenario because we know for a fact that is incorrect yeah yeah exactly so that's probably the big thing for her so i mean if anything i think it really demonstrates that every person is different and their obstacles and their mental barriers are different and you have to approach them all differently also she is the type to get very frustrated if you over correct or you nitpick so i have never been super i've never been a super stickler about her form yeah You're not like barking at her between right now.

44:09So no, no, no. So even if her hips sag a little bit in the pushup, I don't, I'm not going to, I'm going to leave it. You know, I'm like, you're still doing the reps. You're, you're still getting the benefit of the exercise. So I'm going to leave it. So I think that has been another important thing for her is to be like, okay, keep it a fun environment where she doesn't get frustrated. Yeah. One of the interesting challenges I would have not predicted is that, so Leonard, I film him quite often just to like show him. Cause if he's like, this is heavy or this is light. And I show him like, well, actually the bar speed is kind of indicative that it actually is a challenge.

44:39But he will invariably post these things on Facebook as people, which is great. That's pretty sweet. Yeah. Totally. But like one of his recent deadlift sets, he did 275 for a couple sets of four. Yeah, right? I'm like, Leonard. Yeah. What a savage. Yeah, that's serious. But the comments underneath are not like, you know, go Leonard, go whatever. You know, they're more like, you're going to hurt yourself. Of course, yeah. So, you know, and it's like, and even in the gym, I've had people like try to pull me aside. and like, hey, are you sure that he should be doing these things? And I'm like, I'm pretty sure.

45:09Like, I'm pretty sure. Maybe if you want to look up barbell medicine. So obviously you're in a private setting so that you're not getting that in person. Oh, that would really annoy me. But it's, I mean, it's to be expected, I guess. It's almost like this learned fragility kind of thing or learned fear. This idea that if you're older, you're fragile and you can't, you're not capable or you shouldn't be lifting heavy things. And I think it's disempowering. It does us a disservice. Yeah. If anything, that population is more vulnerable to the effects of detraining and insufficient activity. And so most – what I find is that most fitness advice geared towards that audience, they results in underloading and undertraining.

45:50And I'm like it's better than nothing, to be clear. No hate comms, peace and love. It's better than nothing. But from like a maximizing the return on investment for time, let's put our best foot forward. Let's make sure it's an adequate resistance. You're doing an adequate number of reps. It's getting appropriately challenging. It shouldn't be maximal, but you're getting there. And rinse, lather, repeat. But these are people like, ah, no, you can never touch a barbell. I'm like, well, God forbid you got to pick something up off the floor in your day-to-day life or like sit down on the toilet and get up by yourself.

46:19I mean what's your – never squat. Like how do you interface with the environment? Yeah, and I think it also comes from those people who grew up in a generation where lifting weights wasn't that common to begin with. and especially i know i'm obviously um you're training your dad i'm training my mom but like women my mom growing up no one lifted women didn't lift at all yeah and so i think for them to even even for my mom when i have her dad lift like even like 115 125 pounds she's always like there's no way i can do this and i'll film her i'll send her the video and you know she was objecting the whole time she was doing it but then she'll go and send it to all her friends yeah yeah yeah that's pretty cute she's like oh look at how much weight i lifted uh so it's pretty cute but also it shows that there is a lot of learned false narrative.

47:04Yeah. That social learning component is huge. With how much you should or shouldn't lift, how much you should or shouldn't do or what we're capable of. And yet, obviously, they experience the benefits of it. Yeah. And then we know too, you know, there's research on participants in their 60s and 70s. You can still gain muscle and strength when you're older. So there really is never a point when it is too late to start lifting. Yeah. I'm mostly concerned. Which is really cool. Yeah. When it comes to exercise prescription in this population, if this was a special population, which the only reason I view it as special is like, look, most of these people are not active, which makes it special by default.

47:38But my biggest concern is underloading versus overloading. That seems to be more common. Has there been anything surprising that she's been able to do either in training or as a result of her training that you otherwise would not have guessed? I imagine a scenario where you're like, I don't know if mom can overhead press, for example. Oh, shoot. She's amazing. she's so good or a pull-up or i don't know anything like that that's happened that you've been surprised by uh i think her deadlift progress has been really good i will say that she still struggles with uh like proper hip hinge especially when it comes to like to the conventional deadlift versus trap high bar trap bar deadlift she's a lot more comfortable with but um it's been really cool to see her grind out some pretty heavy reps that even when she's like there's no way i can do that And then she does like six, you know?

48:24Yeah, she's like, oh, just kidding. So that's been really great to see. And then obviously outside the gym, she is very independent. She does a lot of things on her own, which I love to see. And I'm hoping that that continues for a long time with her. Yeah. Yeah. Pops, we had been doing a bunch of lap pulldowns and variations thereof and rows and such. And I had this wild hair just to propose the idea to him because he was a Marine. He was in the military. And I was like, hey, do you remember, like, could you do a bunch of pull-ups like back in the day? He's like, oh, yeah, I was excellent at him.

48:54I'm like, you think you could do a pull up or chin up now? And he's like, huh, I probably haven't tried one in over 20 years. I'm like, well, why? Oh, my gosh. So I showed him. Right. And just do this. And he got up there and he cranked out three chin ups like right in a row. We had not. And I was like, dad, holy crap, man. What the heck? That's very cool. That one. And then there's a golf course that we play called Medeiros. And there's a forced. My dad will not move up a tee box. He just refuses, and we go back and forth. But anyway, there's a forced carry. I think it's 165 yards, whatever. And he's never been able to make the distance off the tee.

49:31And then, I don't know, a couple months into training, he finally does it. And he looks at me, and I go, either you got much better at golf all of a sudden, or this added strength is paying off. So now he's like, how do I swing the club faster? I'm like, all right, well, I don't know when you do speed training or anything, Leonard. But we'll just keep getting stronger and see what happens. Yeah. And I think using those kinds of motivators to get them to keep showing up and get, stay excited about lifting. I would absolutely use that to your advantage. Cause I do say this is going to help you to golf swing.

50:02Totally. This is going to give you a more powerful hip rotation, this and that. And she's like, Oh, that's great. I want to do more of this. And so a lot of, a lot of people, their main motivation for lifting is not, I want to be really good at lifting. It's, it's, it's either like, you know, general health improvement, or I want to get better at this thing outside the gym. And I think it's totally valid to have those reasons. And I would use that to your advantage as much as possible. Yeah, it's a great leverage point for motivational interviewing to do stuff. Not everybody is cut out to be a power lifter.

50:31And then also if you're like a science-based lifter, and that term has been used derogatorily as of late. But like you don't have to be like – So is educated apparently. That's true. You're educated. Actually, this is not the best exercise for like club head speed. I'm like, dude, shut up. Come on. Yeah. So I'll wrap this portion up. This is maybe the most important question I've ever asked on a podcast. So no. What advice do you have for somebody who wants to get their parent or loved one started in the gym? Obviously, you're in your mom's relationships close otherwise. And she knows you're a fitness professional and you have resources.

51:06Oh, just come over the garage or come to the warehouse gym. But a person who maybe doesn't have that background personally and that those resources personally, any sort of advice that you would give them here? Yes, I would try to, I like to keep an open invite for lifting. For example, there was a time, I want to say last year, the year before, when my mom's older sister was visiting for several weeks. And she would come over with my mom when my mom would come over to train at my garage gym. And my aunt, who doesn't really exercise, she would stand in the garage doorway and watch us as we would work out, we would lift together.

51:41And I'd always say, do you want to join? No, okay, that's fine. And then by week, the end of week two, she was like, okay, I'll try something. And I had her do like a 10 minute workout. And I wish she would have stayed for longer because, you know, I would have gotten her to do more and more. But it was very like, you don't want to force them. You don't want to scare them. You want to, I think like, you know, let them become curious and watch you over time. I think a lot of being a role model is really, really important to show that you're doing the thing. And so she'd watch us the whole time.

52:09And she finally was like, okay, I'll try this like low box step up, body weight step up for now. And then I'll do this, um, these rows and these, these, these, this, this dumbbell bench press and things like that. And, um, so I think leaving that door open is really important rather than making you feel like you're forcing them. You shouldn't be forcing them into like, you have to do this or else blah, blah, blah. Um, and the other thing I would do is find out what their biggest barriers are and remove those barriers as much as possible. For example, if they don't leave the house or they're afraid of being watched by other people, can you bring some equipment into their home and modify workouts that they can do in their living room?

52:46And take them through a workout. Let's do something for 15 minutes, one five. I don't care if it's ideal or whatever. All I'm trying to do is get you building the momentum of exercising and then over time we can always add from there. So that's kind of the approach that I would take. And again, make it fun. What music do you want to listen to? Do you want to have a TV show on in the background? I don't care. How can I make this fun for you? I think that's really, really important. It's great advice because – yeah, and I'm sure you get this question all the time too. It's like, oh, how do I get this person in my life that I care about to exercise?

53:16And invariably where people tend to start, at least my experience has been, people want to extol the benefits of exercise. They want to do this long oratory of like, well, the data shows this or like – and it's like, look, most people by and large know that exercise would benefit them. That's not going to like trigger this, wow, now I'm so motivated. Thank you so much for your hour-long dinner time table talk. Instead, it's like, hey, why don't you come work out with me or why don't you let me show you some stuff in the gym? Like basically you're making it a little social. You're removing that barrier.

53:52You're removing the barrier of like, hey, I've never been to this. I don't know how to do the exercises. You're checking all of those common barriers off. And so there may be additional ones for the individual that in that case you would handle specifically. But yeah, I find like, look, don't you don't got to preach these people the same way. You don't have to tell a person who's smoking. They know. Stop it. Stop it. Yeah, they know. Yeah, we're right. It's how do you facilitate that? Yeah, actually. OK, so that reminds me. I don't know that I've ever talked about this publicly before, and I think it's OK for me to talk about.

54:19And so one of my chapters of my thesis, and we collected data on this too, we're trying to get it published, was a survey on perceived benefits and barriers to lifting in women. Right? Perceived. Right? And so we had women who self-identified as regularly resistance trained versus non-resistance trained. So people who lift regularly versus not. And we found actually that both groups had similar levels of perceived benefits to lifting. so even if you don't lift you understand the health benefits totally so you're to your point you're totally right there's no we don't have to be like this is what it's good for yeah okay that's great like we know that but it was obviously the difference came down to the non-lifting group their perceived barriers were much much higher and again i i think it's important to emphasize perceived totally because when you think you have less time even if you do have time you're going to feel more overwhelmed and you're going to be less willing to do the thing.

55:16And the biggest barrier was time effort. Uh, and social barrier was a, was a big one too. So how can we address those exact barriers? Okay, cool. Hey, um, can you find, uh, two jugs of water or sacks of rice around your home? Then you can live with me in your living room, you know, 20 minute follow along, do this with me. They're like, okay, I can do that. Then I can stay in my outfit. I don't have to change. I don't have to be embarrassed or self-conscious of other people watching me. And I don't have to worry about a commute to and from the gym. Done. I've addressed all those things. So lots of ways to facilitate that.

55:56Yeah. The ultimate goal is to get people bit by like this physical activity bug, this exercise bug. Oh, I feel good. Yeah. Oh, yeah. And then I think it's almost human nature and I'm not a psychiatrist. This is not my area of expertise, But I think there is something that once you get that first taste of a win or success, that then people are like, how do I do it better? How do I get more out of this? How do I – and it's kind of a positive feedback loop, but then people are probably more open to, oh, maybe I would go to a gym. Maybe I would do something a little bit more, quote, optimal for the educated people.

56:28Yeah. Yeah. And well, yes, actually, that's a good point, because I think a lot of people, they're so they're so consumed with it has to be done perfectly or it has to be done optimally or I'm not going to do it at all. And I'm like, I don't care about what's optimal as long as you're doing something. And then we can always improve upon that over time. Yes. Yeah, agreed. Anyone who's able to should exercise. We want you to do as much of it as possible. But anything is nothing for sure. Yeah, which is why I think a lot of the debates we see online, like splitting hairs over, like what exercise and what angle of this and that exercise is.

56:59I'm like, I really don't think that. Couldn't care less. Important. Like not even a little bit. No, won't find me in the comment section. No. Yeah. No, this is great. This is excellent. I am sensitive to your time. And also just every time I get to talk to you has been amazing. So before we go, can you tell people where to find Dr. Sohee Carpenter? Yes. So my username is SoHeFit across every social media platform. I would say I'm most active on Instagram, but there's also a website. I'm on, I guess, Thrive is technically considered a newer social media platform. I'm like somewhat active on there too, but I'm on all the major platforms, SoHeFit.

57:42I'm pretty easy to find. We'll link all of our stuff in the show notes below. And as always, it's been a pleasure. Before you guys go anywhere, please leave us a five-star rating and a review.

From the publisher

In this special episode of the Barbell Medicine Podcast, Dr. Jordan Feigenbaum welcomes back friend of the show, Dr. Sohee Carpenter, PhD, to share her latest insights following the completion of her PhD in Sports Science from the Auckland University of Technology. 

We dive deep into the research from her recently published paper in the European Journal of Sports Science, exploring a highly relevant question for strength athletes and the general population alike: How do high-intensity circuit training (HICT) and traditional strength training compare?

Key Topics Covered:


  • PhD Research Deep Dive: Dr. Carpenter breaks down her study, which compared HICT against traditional resistance training in trained women over an eight-week period. The groups performed the same exercises, sets, and reps, and pushed to similar proximity to failure, with the key difference being the rest periods.
  • The Results: Find out the surprising, yet encouraging, findings regarding strength gains and muscle growth between the two popular training modalities. The results suggest that for many, personal preference, time constraints, and gym logistics should be the deciding factors for training style—as long as you push close to technical failure. 
  • Circuit Training & Time Efficiency: We discuss why circuit training is a popular option for time efficiency—her study's circuit group completed their sessions in approximately 50-55 minutes, compared to 70-75 minutes for the traditional group. 
  • Coaching Loved Ones: Dr. Carpenter shares her personal experience and advice on training her 64-year-old mother. We cover how she successfully addressed barriers like accountability and self-efficacy, starting with short, positive sessions (initially only 20 minutes) and gradually progressing to longer, more challenging workouts.
