Hey, this is Philip. I have a quick bonus episode for you today on a Saturday, and it's short because the subject of the episode is saving you time. So I want to keep this short. Now, on the last episode 500, I gave you five things that I got wrong. And the pattern that was consistent across those was that I was overvaluing overvaluing a small variable and undervaluing a big one. So here's a real life version of that. And it's really good this time of year because we're in September, past Labor Day or Labor Day weekend when everybody's back into school. So a lot of us are parents, a lot of us are over 40, and your schedule got a little bit tighter, and maybe you're trying to switch up your routine, or maybe you're you don't have as much time in the gym or whatever. And I wanted to talk about rest periods between sets. This could be a game changer for you. Now, you hear a lot of advice or a lot of rules, I'll say, like, hey, you need this many minutes of rest for this type of exercise, or maybe you're wasting time if you rest too long and you'll get a better workout and you can shorten your workouts with less time. But in reality, we've got to balance a bunch of things. We've got to balance our life when we train, how much time we have in the gym, what types of lifts we are doing, our work capacity, you know, all of these things, whether we're in a fat loss phase or not, of how fast we can go through the workout and how long those rest periods can be. And that's why there's so confusion, so much confusion about it. So today I want to just quickly tell you why that number isn't necessarily what you think it is and how to how to approach this instead, depending on how much time you have to work out. So let's start with rest and muscle growth. There was a study of Bayesian meta-analysis in 2024 at a Brad Schoenfeld's group at Lehman, and these guys put out most of the good work related to this, these types of questions. So I read a lot of what they published. They actually pulled nine studies and they compared short rest, intermediate rest, long rest, and very long rest. And the effect sizes across the four buckets, there was a lot of overlap, a lot of overlap. So for muscle growth specifically, it turns out that the duration of your rest period is really not the big lever. And I've talked in the past, like it is. Many people do, like, oh, if you, you know, starting strength does that a lot. They're like, you have to rest at least three to five minutes or more for your compound lifts. Now, that's not the same as saying that rest doesn't matter. So I want to explain the difference because today's Saturday, if you're gonna go into training Monday, this could help you out. What rest is most beneficial for is to help you with your next set. If you come back too soon, if you're not recovered from a either fatigue perspective, but even from a work capacity perspective as well, then you'll end up doing fewer reps at the same load, or you might even have to drop the load to get the reps when you didn't program it that way or wouldn't have done that. And you end up getting either less volume or less intensity than you planned. Now, on the last episode 500, I talked about proximity to failure or effort being the thing that makes your volume actually count. Okay. Well, you can't get close to failure with a meaningful load on, say, your third set if you are still completely gassed from your second set, or if you have some built-up fatigue that hasn't dissipated, even though it can't all dissipate, you know, you have to get some level of recovery. So it's not that rest periods are doing something magic to your muscles, it's just that it's buying you the recoverability and the ability to do the work for the next set. And this tends to matter more for strength than it does for hypertrophy. The time efficiency review that I mentioned earlier puts it at around one to two minutes for beginners and at least two minutes for train lifters, especially on compounds. So that sounds like not very much time, right? And I think the mistake isn't that you're resting too long. There's nothing wrong with resting longer, right? It's just going to take more time. I mean, that is the big the best thing. The first thing everybody reaches for when they're trying to save time is often shortening their rest periods. I get this all the time: like, hey, is it okay if I just rest for shorter amounts of time to shorten my set? And I don't think that is the best lever to pull. I'm gonna give you the best one in a second. Before I do, I have to tell you about my app, Fitness Lab, because it is tied to this subject very relevantly right now. We just released a huge update with a new and improved workout logger. And the way that we designed rest periods into the app is actually pretty cool. It's very adaptive. I don't, I haven't seen any other app on the market that does this. In Fitness Lab, when you fat Fitness Lab, when you finish a set and you log it, a rest timer starts, shows you the time before your next set. Okay, great. A million apps have that. You know, there's not a timer during the set itself. We're not a guided workout in that sense. We're not going to time you before you start. None of that stuff matters, right? You might be waiting for the rack, you might be talking to somebody. We don't care about that. We want you to have some good work in your training session. But for the rest period, there's often confusion about how long I do that. So the way we design this is compound lifts get the longest rests and isolation lifts get fewer. So the smaller the lift, the shorter the rest period. But cooler than that is if your session is shorter, like if you say, hey, I only have 30 minutes to train instead of 60 or 90 minutes, we actually scale those a little bit. We actually scale them down a little bit. Now, the app is smart enough to know that if you're only doing, say, three lifts and you've got a full hour, there's no need to scale it down. But if you're trying to fit in a bunch of lifts and you only have a certain amount of time, the app is going to scale the rest periods down, but within reason, within still the window that it needs to give you adequate rest, if that makes sense. Right. So that is pretty cool. Now, the app will also simply remove movements or working sets to help meet the time. It'll do a bunch of smart ways to give you the right program. It doesn't squeeze the rest periods to be shorter than necessary just to make the math work, just like the research says, you know, we don't want to do that. And that is what the app does.

And that is for the latest and greatest release of Fitness Lab with the all new workout logger. All right. So the better lever, I think, instead of just shortening rest periods, is to change what you do during the rest periods. What do I mean by that? Well, let's talk about supersets. There was a meta-analysis last year of 19 studies with 313 people on supersets. And what I mean by that is you pair up two exercises back to back and then take your rest after the pair. Now, you could superset a warm-up for a lift while you're working in between the sets of your previous lift. That's another way to superset where you're not really supersetting the working sets, but you're supersetting the warm-up of the next set. And I love to do this for smaller movements like biceps and triceps, for example, or leg extensions and hamstring curls. And what they found in the research is that supersets, of course, they cut your duration of your session. They save you a bunch of time. In some cases, close to half, which makes sense. You're doing two instead of one at the same time, but without compromising your training volume, your muscle activation, perceived recovery, long-term strength, hypertrophy outcomes. And we've seen this in a lot of recent research. That is very, very powerful and could have a huge effect on your actual life if you're trying to save time. Now, the P the thing where people screw it up is they pair the wrong exercises. You've got to pair exercises that don't really compete with each other if you want to get the most out of this and the minimum fatigue. Now, you might pair exercises that are similar on purpose. That's a different thing, but just in the interest of saving time without compromising anything, you might pair a push with a pull, a row with a press, upper with lower, you know, a biceps or triceps, right? Agonist or antagonist muscles, they call them, because that way you're not hitting a tired muscle already. It's fresh for both. All right. So supersets are a great way to do that. Now, there are some, I'll say, trade-offs with supersets. One is that they do feel harder because you've got this higher perceived exertion, potentially a little more muscle damage, but that's that's kind of a side thing that I'm not as worried about. Possibly more recovery needed before the next session, but I really minimize most of those things because I've seen for most people it's just a practical savings in time. You might need a little more work capacity, you might be a little bit more out of breath. You can still take a little bit of rest period. You don't have to just go bam, bam, bam, bam. You could still take 30 seconds, but you're you're saving, you know, one, two, three minutes each set and it really adds up. So I wouldn't superset like major movements, like a squat with something. Again, unless you're just supersetting the warm-up of the next period. So if you want to get a good amount of quality work into like, you know, 30 minutes, but really get a lot of intensity in there, this is a great tool for that. And I wouldn't do with everything, I would do it with a couple pairs of exercises. So again, if you're looking at rest periods, I would still keep them long enough to recover to be able to go hard on your next set. And the only time I would shorten them is for special cases, like if you are deliberately trying to work on your work capacity or speed work, or in the case I just said here to save time but without really compromising anything because you're overlapping exercises. So you're essentially getting the rest period built in when you're working on the other exercise. All right, before you go, the Labor Day deal and Fitness Lab closes September 13th.
