In short
Whether training each muscle group twice per week is superior to once (and how it compares to 3+ times), with emphasis on hypertrophy, fatigue management, and real-world adherence. Guests/hosts: Sal Di Stefano, Adam Schafer, and Justin Andrews (Mind Pump Podcast hosts; no outside guests mentioned).
Key claims
Controlled studies show twice-weekly training produces more hypertrophy than once; extra frequency beyond two shows diminishing returns for muscle (3x may help strength more via skill practice). Real-world benefit: splitting volume reduces fatigue, increases effective volume (sets, reps, weight), and improves performance.
Notable examples
Bench press volume split (10 sets Monday vs 5 Monday/5 Thursday) illustrates volume control; plyometrics should be explosive with long rests (not repeated reps) to avoid training stamina; training close to failure too often can “fry you,” so stop 1–2 reps short. Example split: upper-lower, day off, upper-lower (MAPS Upper-Lower).

0:13Adam Schafer:Approaching over half a billion downloads, this is the Mind Pump Podcast, the best in fitness, entertainment, and health. Today's episode, we talk about whether or not you should train your body parts twice a week. Is it superior? Short answer, yes, and we break it down for you. By the way, we have a brand new program that we just launched that follows this kind of a split. It's an upper-lower routine. It's four days a week, upper-lower, take a day off, upper-lower. It's brand new, so it's 40 % off. Go to mapsupperlower.com. Use the code LAUNCH. That'll give you the 40 % off discount. This episode is brought to you by our sponsor, Element.
0:50Adam Schafer:So this is an electrolyte powder. You add it to your water. It tastes amazing. thousand milligrams of sodium. Why? Because if you need electrolytes, you need the sodium, no artificial sweeteners, no sugar. So it's got zero calories. Now, what does this do for people who need this? Well, you get better mental clarity, better athletic performance. Maybe you have muscle cramps or headaches or fatigue. Many people report more energy. I know I do. I drink two of these every single day. So if you go to drinklmnt.com slash mind pump on that link, you'll get a free sample pack of their most popular drink mixed flavors with any purchase.

1:43Adam Schafer:There's often a lot of debate on how often you should train a body part or a muscle group. Well, guess what the data shows clearly there is a superior way we're going to talk about why you should train each muscle group twice a week let's go let's get it this is a cool conversation
1:59Sal Di Stefano:something i've actually mean to ask you because i i know what the data says or what we talk about um when we compare this one time two time or three times a week that you you would train a muscle group do we have is there good studies on four and five and okay yeah and controls controls on a lot of these because what comes to mind for me is when I think about today and the amount of stress and busy and poor sleep and technology and everything like that, like variables like that have to play a role too, right? Like, you know, like somebody, somebody might think that, oh, my body would do better training, you know, training the muscle group three times a week.
2:40Sal Di Stefano:And maybe that's true. If you're very well rested, you're, you know, very well hydrated, you're well fed, you're in a calorie surplus, all these great, you know what I'm saying? Like you're just focused on bodybuilding, then it may make sense that you can train at that high a volume. But like, how does that factor in these studies?
2:57Adam Schafer:So they've actually done some pretty good studies on, on, um, training frequency. So there were early studies that made comparisons, uh, and the, the more frequent, uh, you know, training style, uh, produce better gains in the early studies, but the criticism was that the early studies didn't control completely for volume. So let me give you an example and we'll get more into this as the episode goes on, but let's say you did 10 sets of bench press on Monday versus five sets on Monday and five sets on Thursday, let's say same exercise. You're going to be doing, you're going to do naturally more volume if you do it Monday and Thursday, because you're going to be stronger.
3:39Adam Schafer:So even though you're doing the same amount of sets, because you've split it up, you're able to lift more on Thursday for those last five sets. And if you did those last five sets after the first five sets on Monday. So what they've done under their studies is they've controlled totally the volume.
3:55Justin Andrews:I've always thought of that as like it's just more effective because you'll perform it better at the same time.
4:00Adam Schafer:Okay, so there's two parts here. One is in perfectly controlled studies, and then the second one is how does this actually work out in the real world? Right, which is what I'm interested in.
4:09Sal Di Stefano:Right.
4:09Adam Schafer:So the well-controlled studies still show that training a body part about twice a week is going to produce more gains than once a week. Every additional workout, subsequent workout, you see diminishing returns or maybe no additional gains in hypertrophy. Now, there's a case that the data will make on strength, but that has more to do with skill. when we're talking about just building muscle the the the large body of evidence that we have points to two days a week all all things being controlled same exercise same weights same reps when they control everything two days uh a week or hitting a body part twice a week
4:51Sal Di Stefano:builds more muscle i thought three was superior but it was barely superior and so that was the
4:55Adam Schafer:argument was like you know so three you don't see a huge difference in hypertrophy but you see a difference in strength and that has more to do with skill acquisition yeah that makes sense you're
5:05Sal Di Stefano:practicing i mean in a month's time you get four extra practices that's right that lift so that logically that makes sense you're getting better at these compound lifts and you'll get more that's right but i actually thought that it showed more muscle not a lot but i thought and that's why two tends to be the more favorable amount because it's like once you do once you hit two you're getting 80 90 of the results a whole other day or a whole other workout for 10 more it's like I guess if you had the time and you had the dedication. Yeah.
5:32Adam Schafer:It also depends on like what people like, uh, two days a week, you know, hitting like, for example, doing an upper lower split, which would be a good example of, of this, right. Where you do like, let's say upper body on Monday, lower body on Tuesday, you take Wednesday off and then Thursday, upper body, Friday, lower body. So it's like a traditional bodybuilding split. Love that split. Uh, people like that kind of a split because you get the value of the additional frequency that builds more muscle, but you also get the kind of bodybuilding feel the pump within the workout. Whereas full body workouts, which are typically the, what you're talking about, the three day week, you know, Monday, Wednesday, Friday, full body.
6:04Adam Schafer:You don't get the pump. You don't get to really hyper focus on a body part. And so people who are more interested in hypertrophy and building in the pump, they tend to favor this twice a week. And the data supports like this, this is pretty much where you're going to build the most amount of muscle, all things being equal. So again, the data on this is clear. So that's one reason why you should train this way. The second reason is that fatigue becomes less of a hindrance. So when it comes to exercise or working out, people view fatigue as a good thing. And in some cases it is, right? In other words, if I'm training for endurance, I have to train fatigue.
6:43Adam Schafer:Yeah, you gotta press the limit. I have to press fatigue because I'm trying to get stamina and endurance. With strength, fatigue is a problem. You can't train strength if you're fatigued. If you're fatigued in your training, you're training endurance. if you want to train power or strength the less fatigue there is the more you can train power or strength so this is why sprinters when they're practice when they're like olympic sprinters
7:06Sal Di Stefano:they don't run to fatigue they sprint explosively and then they come back and you notice that they
7:12Adam Schafer:kind of wait for a while i mean this is our biggest in between this is our biggest qualm
7:16Sal Di Stefano:with jump boxes you hear us talk about on the podcast all the time is people do plyos the wrong way if you're training for power which is what plyos are for it should look like this explode and then this long rest period explode and this long rest period not this
7:30Adam Schafer:rep after rep now you're training stamina that's right and this is why you know they've done data to compare like rep ranges and which one builds more muscle and previous studies showed that the lower rep ranges like eight reps ten reps let's say six reps even built more muscle than let's say 15 to 20 reps but then there were later studies that compared the two and so long as the rep ranges or the training is close to failure, they build the same amount of muscle. So then everybody's like, oh, cool. 15 reps or 20 reps builds as much muscle as eight reps. This is true so long as fatigue doesn't get in the way.
8:07Adam Schafer:So give an example. If I go and train one rep close to failure of barbell squats for eight reps versus 20 reps, for most people that night, that 20th rep, what's stopping you is your endurance. You're breathing hard, man. It is not the muscular failure. It's very cardiovascular. Yes. And so it gets in the way. It's my lower reps. So fatigue is not what you want when you're trying to build muscle. What you're trying to do is train strength and power. And so when you split up your volume over two workouts, rather than doing them all in one workout, for example, if I'm doing chest and I'm doing, you know, 16 sets on one day versus eight sets on one day, eight sets on another day, same total sets, but they feel very different because fatigue is not so much of an issue.
8:54Sal Di Stefano:Even though this didn't make your list, I also like this because I like this type of a split. One of the things that I make a point of saying with the full body routine that I like is that you're hitting the full body. And so even if you have a bad week and you only get a workout in or whatever, you at least hit every muscle group. I find the commitment to one or two days a week. And then like, even if you only got two days out of the week and you can pick right back up on that upper lower split, it's easier to do that versus like a, uh, these body part splits that split up to one day to hit that body part.
9:28Sal Di Stefano:Yes. And if you miss that, yes. Which is traditionally what a lot of bodybuilders tend to lean towards this one body part of they or two that they focus on. And I found that like, man, you just got to have a day or two off. And then now it throws the whole thing off where an upper lower is really easy. because even if I did miss a workout or two, it's real easy to get back in the swing of that. And I don't feel like you fall way behind on hitting a muscle. No, that's a good point.
9:52Adam Schafer:That's like a real life. Yes. That tends to be what happens. The other thing is that splitting up your workout in half, let's say. So you hit upper body twice a week, lower body twice a week, split up the exercises so you could do half on one day, half on the other day, both for upper and lower. This allows you to focus more of your effort on the better lifts. So, again, to use the example of, let's say, chest or back, you know, if I'm doing 16 sets for back in one day, the last eight sets are not barbell rows, deadlifts.
10:26Justin Andrews:Your exercise selection is going to be completely different. Yeah. You're going to have to consider what's not going to be as taxing, right, for one, because you're just going to have to keep adding that in. So you're going to lean more towards machines and you're going to lean more towards, you know, certain exercises that build volume, but not necessarily the big movers.
10:44Adam Schafer:This is where the term junk volume came from.
10:46Justin Andrews:Yeah.
10:46Adam Schafer:Is where, you know, someone's doing everything in one workout for a body part. And it's like the first five sets or six sets of the workout are legit. Then the back half, it's like, now I'm just, you know, what do the bodybuilders say? I'm just trying to squeeze more blood in the muscle, trying to get more of a pump. Yeah. Which, you know, feels good. I get that. It's the finisher. your, finish your lifts, right? But they're not the big ones that make the biggest difference. Whereas if I'm doing, you know, instead of doing 20 sets of back on one day, I'm doing 10 on one day, 10 on another day.
11:14I'm probably going to do a good, good, the best lifts on both days, uh,
11:19Adam Schafer:because of the point I made earlier with the fatigue.
11:22Sal Di Stefano:This also, so this type of routine ends up working out to be basically four days of the week that you're lifting. And then the other, So what I like about this too is personally for myself, it takes more mental focus and get up for like leg day for me. It's just more fatiguing. I want to train them harder too. And so because it's just a four-day routine and there's three days of flexibility in there, I schedule my leg days on my days when I'm ready to get after it. I feel like I can cruise through my upper body on a day where I don't feel the best. I didn't get the best rest. I don't feel like I need to feel my best.
12:03Sal Di Stefano:When I want to train legs, I want to feel my best. And so another reason why I like a split like this is that I can shift that lower body day on or put a -
12:12Adam Schafer:The mental state that you're going into. Yes.
12:14Sal Di Stefano:When I'm focused, when I'm rested, when I'm good, it gives me enough flexibility where, oh, today I'm not feeling it. I'm going to take the day off today. Or you know what? I'm feeling great. I'm going to go after my lower body. And then I'll rest tomorrow or whatever.
12:25Adam Schafer:Yeah, this kind of a split, like you're mentioning upper-lower type split, like our MAPS upper-lower program, which is what we're talking about, right, where you're training each muscle group twice a week. It allows for more volume than a traditional full-body three-day-a-week routine. Because once you start to ramp up the volume on full body, the workouts get too long.
12:43Sal Di Stefano:Yeah.
12:44Adam Schafer:They can turn into long workouts. But when you split it up this way, now the time comes down, but the volume is higher because of the way it's split. Here's the other thing, too. when you train a body part twice a week versus doing all of it once a week, volume naturally goes up. So there are a few things that are connected that we can directly connect or correlate to muscle growth. One is strength. Okay. We talk about this all the time on the show, like, especially in the first few years of your, of your consistent lifting career, let's say, if you're going to, if you're getting stronger consistently, that tends to translate almost reliably, like 100 % reliably to muscle.
Read the full transcript
13:23Now, later on, it's not so reliable.
13:26Adam Schafer:You know, once you get really strong, it's not like adding, you know, 15 pounds is going to really make a big difference when it comes to muscle. But in the first few years, the best thing you should do is chase strength. But there's another thing that is even more closely related to muscle growth that seems to be related regardless of how you've been lifting, how long you've been lifting. And it's connected in the beginning. It's connected 10 years later. and that's your total training volume. And volume naturally goes up when you split up your body and train it twice a week instead of once a week.
13:57Adam Schafer:Why? I made this point earlier. You're stronger.
14:00Justin Andrews:Yeah, you're not fatigued. You're able to actually like perform the lifts well. And then again too, you're able to actually like load and progressively overload and then work on the strength aspect.
14:11Adam Schafer:And that's volume. So volume people tend to think, I used to think this, I thought volume was just sets. Yep. But it's not. Volume is sets, reps, and weight. And so if I'm doing, you know, let's just create a hypothetical, right? Let's say I did 15 sets of barbell curls. Okay, let's just say. All in one day. And let's say I used 70 pounds. And my first set was 10 reps with good intensity. I'm sure by the 15th set, I'm going to be down to like six reps. Yeah. Or five sets. But if I did, if I split that up into two workouts, I would be able to complete more reps with that amount of weight. Even though the sets are the same I did more reps, volume went up.
14:53Adam Schafer:And so this is where the studies that are really controlled I don't think they tell the full story because they're controlling perfectly for everything. No, no, no, do this many reps, do this much weight. But in real life, when you split the body up without even trying because you've split up the volume you end up doing more volume because you're not as fatigued.
15:12Sal Di Stefano:And what's nice about that is volume actually goes up. And then the way this is split up, different than like a full body, is you actually get more rest before you come back around to that too. So typically, if you have a three-day-a-week routine, it's like a Monday, Wednesday, Friday. So every other day, you're coming back.
15:26Adam Schafer:Oh, this will be Monday, Thursday, or Tuesday and Friday. Right.
15:28Sal Di Stefano:And so you've got a nice two days in between before you come back around to those muscle groups. And so with the volume naturally going up, needing a little bit more rest and recovery, this is personally one of my favorite splits.
15:40Adam Schafer:Yeah, especially when you were getting the volume up a little higher.
15:43Sal Di Stefano:Yeah, and it's not too much, though, either. And even though we're talking about it being laid out, in a perfect scenario, it's laid out, like you said. It's the upper, lower, day off, upper, lower. But again, I always like looking at things real world, like bad week, I only get one in. Sometimes it'll look like, so for me, lower body is always the main focus. That's my weaker part. And so if I have a rough week, I'm going to make sure I at least get my lower body in. And then I'm going to pick up right where I left off the very next week.
16:14Adam Schafer:Yeah, so it could be like upper, lower. Oops, I missed a bunch, but I'll jump back in. That's right.
16:18Sal Di Stefano:That's right. And so it's like, and it's still, it's the way I like training if I'm not doing a full body routine. And I like that I still get to get that little bit of a pump. Because as the guy who likes to do bodybuilding type stuff, the one thing I don't like about full body is I miss that.
16:35Adam Schafer:I feel like this kind of a split is a nice bodybuilding slash strength building split because the skill acquisition aspect that we like so much from practicing lifts frequently is a little bit here, right? Yeah. I'm working my legs out twice a week. I get to practice squats twice a week, or I get to practice rows twice a week, or bench press, or overhead press twice a week. and there is value in practicing exercises more frequently, all other things being equal because lifts are skills.
17:09Justin Andrews:Well, I would say that's probably the difference, major difference between our version is the emphasis on those specific type of barbell lifts because you don't see that in every split program, especially upper or lower. It typically leans a lot on machines. Yes, yes.
17:25Sal Di Stefano:Now, if you were advising somebody, because I know we talk about this a lot on the podcast, but yeah, I feel like we still get this question of like, you know, is this for bulking or is this for cutting? It's like every program could be either way. But do you think because certain, like for example, this one has naturally volumes going to go up, naturally it's leaning towards kind of strength and bodybuilding. Do you think it bodes well or better for somebody who's trying to build?
17:51Adam Schafer:I think, I would say if we were speaking specifically to the kind of split that we're talking about, which would be like our MAPS upper-lower program. This is a moderate volume, bodybuilding, muscle building routine. You could do an upper-lower split and make it really crazy where it goes upper-lower, upper-lower, upper-lower. And that would be a super high volume style of training, which most people wouldn't do well on at all. 99 % of people.
18:21Justin Andrews:Six days a week, yeah.
18:21Adam Schafer:Yeah, that's like our MAPS split program. Yeah, that's getting way too high of volume.
18:25Justin Andrews:Yeah.
18:26Adam Schafer:This is a really good moderate, like this is going to build, this is a great muscle building program. Now to your question, Adam, I tell you what, like anytime you do strength training, your goal is to build muscle, whether you're trying to cut or build. Sure. Because if you're trying to cut, you want to keep the muscle. You're trying to build, you're trying to build. Yeah. And so, yeah, no, this is an excellent program.
18:43Sal Di Stefano:I think it follows MAPS Anabolic really well too. Totally. Yeah.
18:47Adam Schafer:It's a great followup to that. It's a great followup to PPL.
18:51Justin Andrews:Yeah.
18:52Adam Schafer:It's like. It's a progression from that. It's the perfect kind of moderate volume. Like I'm consistent. I train. I'm a normal person though. I'm not some like crazy genetic anomaly. Yeah. I'm natural. I have a regular life too, but I also like going to the gym. So you got your four days a week in the gym and the volume is split up very nicely. Yeah. And you get phenomenal results from it.
19:14Sal Di Stefano:And I, you know, I should know this. Justin will probably know better than me, but this is the first time we ever created a program that is specific to four days, right?
19:21Justin Andrews:This is, this is a, yep. The only one I know of. Yeah. That's actually a four-day routine.
19:27Sal Di Stefano:Almost everything's either been three, six. Some five, yeah. Do we have a five? We do have a five, I believe. Yeah. So I don't think we have a four.
19:36Adam Schafer:And we also made a men and women's version in here, just the programming's a little different. Emphasis, yeah. Women tend to want to build more glutes, more delts, guys a little more chest, quads type of deal. So the programming's a little bit different. But what you'll find, because I remember years ago, So the first time I switched to hitting each body part twice a week, one of the mistakes I made was I just duplicated my workout. So I just doubled the volume and hammered out the intensity and over-trained like crazy. And then when I realized, oh, wait a minute, I should cut the volume in half, try it twice.
20:11Adam Schafer:And I thought, what's the difference? I'm doing all the same amount. Is it going to be the same thing? No. I got way better results from training this way. Because you'll be stronger, like you said. I was stronger. I felt better. I built more muscle. yeah um and it just recover well at those days that's right now here's the thing training like this i think this is important to know and again the data supports us for pretty much any program but especially if you're hitting a body part more than once a week is you train with intensity but you don't train to failure so that's a big mistake someone may make when hitting a body part more than once a week as they train to failure all the time that'll fry you and will actually cause things to go backwards uh and again the data supports us pretty much for any kind of programming but you're stopping about one or two reps short of failure now do you do you have a like when you're when
20:54Sal Di Stefano:you're splitting this like this do you tend to one day of the week you know you're bringing a little bit more intensity versus the other day yep yeah so that's how like the typically what i what it looks like for me is back again back to that point i'm making about my legs like the day there's there's always at least a day in the week where i'm well rested i'm well fed and it's like and i go and i feel good it's like okay i'm getting after legs this day and then my next like day we'll be more kind of going through it more of the practice bringing the intensity down
21:21Adam Schafer:a little bit it's typically the first two workouts of that week or the heart that's the idea monday tuesday heavier that's thursday friday that's how it is weekend that's right yeah that's how it is
21:30Sal Di Stefano:ideally for me the only thing that would make that pivot and change is if i'm going into it and i don't feel good then i'm like okay the next one i'll get after today i was going to go through
21:37Adam Schafer:the and then just just to add a little extra i mean we're going to go a little into the weeds here but to what you were saying adam if you're more upper body focused or more lower body focused I like to eat in a much higher surplus the day before. So if I know tomorrow's upper body, then I eat more, right? If it's legs for me, well, then I'm going to eat more the day before to fuel that one workout that I'm looking for. And what's cool about this is, and a lot of people are trying to train a very balanced physique, but a lot of people are like, look, I work out the whole body, but I want to focus on my legs.
22:10Adam Schafer:Or, hey, I train my whole body, but I want to focus on my upper body. And you can kind of do that with a program like this where you place more emphasis on - That's why I like that.
22:16Sal Di Stefano:That's where I am. I mean, I spent a lot of my early teens or even early 20s of being very upper body focused. And so most of my 30s and 40s has been more balancing out lower body. So if I miss anything, I'm going to skip arms. I'm going to skip an upper body type of workout, but I'm not missing legs. Legs are going to get hit every single week. And then I want to put more of this. This type of routine lends itself well to that, where it's just like that's what you're going to get after. Yeah.
22:44Adam Schafer:So we have a program that follows this split. It's a four day a week routine. It's maps upper lower. You can go to maps upper lower.com now, because it's a new program, it's 40 % off. So we do this anytime we launch a brand new program.

Short answer: yes. Training each muscle group twice a week builds more muscle than once a week — the data is clear on this, and Sal, Adam, and Justin break down every reason why in this episode. From how fatigue silently kills your volume to why junk sets pile up when you try to cram everything into one workout, they pull back the curtain on what's actually happening inside your body when you split things up.
You'll also learn why total training volume — not just sets, but reps AND weight — goes up automatically when you split your body across two sessions, and why that matters more than almost anything else for building muscle long term. The guys connect the science to real-world scenarios: bad weeks, missed workouts, leg day mental prep, and how to fuel the sessions you want to crush.
They also walk you through the brand new MAPS Upper Lower program, a four-day-a-week upper/lower split built around exactly this training philosophy. It's the first four-day-specific program they've ever built, it comes in both male and female versions, and it's 40% off right now during the launch window.
