 Question is from Dressfit. What do you guys think about daily undulation? They're referring to probably what, nutrition? No, no, no, no, they're talking about exercise programming. Oh, so changing, so undulation essentially is changing your exercise programming, but on a daily basis in terms of the fundamental aspects of your workout. And because when you see studies, the studies will show that this, so they did a really good study where they did this, whether you did it daily or you did it in phases or periodized it, periodized it, did I say that right? No, I can't say it. Periodized, periodized it. No, pure, fuck, now I can't say it. Periodized, periodized. There we go. Doug, are we saying it wrong? I don't even know now. Periodization, periodized, yes. Right, that would be the short? Yeah. Okay, so you got me all over from that intro, I'm all over the map right now. So they did that and then they did some, on a group that didn't change at all. And they found that daily and then like every three weeks was almost the same and a little bit better in daily. Now this was a shorter study that was only, I think a few months long, but at the end of the day, we know that it's important that you change your exercise up. Now, I used to do it every single day for a long time. Now why I like the way we do it now, how most all the maps programs are, where we phase it in blocks. Yeah, in blocks of two to four weeks. What I think is better about that, and even though the studies have shown that they're pretty much equal, what I think is better about that, it's easier for me to gauge and see things and see progress. So if I'm constantly changing exercises and changing rep ranges and changing all those things up on like a daily basis, it's really hard to see like if I'm doing something and I'm consistently doing it, if it's making progress or I'm getting better at it or which movement or exercise, I'm getting the biggest bang for my buck because there's an individual variance in all that with each of us. So maybe a movement for Sal is just okay, but for me like, wow, I've noticed huge strength gains when I did that or it feels great when I do it or whatever. And when you are constantly changing it every day, it's kind of hard to measure those types of things versus following a program or sticking to something for a good solid three to four weeks and then starting to change everything up. I found that was something later on that when we, and this is something that we did together. I know Sal, the first maps in a bulk was created this way, but all of the maps programs are based off of this foundation and to me, I think that's superior. Yeah, so it's really a difference between doing, training in the let's say four to six rep range for three weeks versus training four to six reps on Monday and then Tuesday is 12 to 18 and then Friday is 15 to 15 reps and then it's one to three reps. So daily and daily we're just changing it all the time versus staying within a particular rep range or a particular style for a week or two or three or even four. Now here's the thing, our opinion is based off of our experience training a lot of people. And I would surmise that if you took a large enough sample size, if you did enough of these studies and took a large enough sample size, you would find that the blocking or phasing of people's workouts rather than daily undulation will be more successful because for one of the reasons, which is what Adam said, people can learn about their bodies more. They learn what it feels like and how their body responds when they train just in low reps for a little while or just in moderate or high reps or when they train in a particular style for a little while. And that is priceless by the way. Here's the thing, if you want consistent long-term success, the most important factor is knowing your body. Learning your body is what's gonna contribute to long-term success more than anything else. And for general population, learning your body means you should stick in something for long enough to learn it, understand how it feels and how you respond to it. The other thing is this, and this again, you're not gonna find this in a couple small sample studies. You'll find this in large sample studies or lots of them, is that when you're training in a particular phase for three weeks, there's a mindset that accompanies it. So what I mean by that is when I go to the gym and I approach a workout where I'm training in the four rep range and doing longer rest periods, it's a very different mindset than going to the gym and training with supersets for 12 reps. And that mindset actually develops and solidifies over the course of one, two, or three weeks versus flipping all the time back and forth. Well, it's like sharpening up on your skills versus just reacting to the day. So I don't know, I look at it differently in terms of I wanna get better and I wanna be able to see progress. So I have to have benchmarks to sort of guide the way. And there's certain exercises that are gonna be higher in the priority list and a rep range that I wanna see how my body can improve upon. And the only way to do that is to repeat it enough times to really have a proper assessment of that. So I mean, in the argument of just changing it up all the time, maybe you could make that for just, if I'm constantly, I'm in an environment where I have to react to things constantly. And I have the ability where now I'm creating this new skill of being hyper responsive towards all these different forces at once. But in terms of me being able to really assess that I'm getting strong in this direction because of this, I have to extract that out. I mean, I see value in it if you're somebody that has been training for a really long time and you've already gotten good at all the skills. You know your body. Yeah, you know your body really, really well. This isn't the learning process. This isn't your first five years of training. You've been training for decades and you know, and so you like to switch these things up on a very regular basis. I don't see any problem with that. I just to Sal's point that our advice comes from training the general population. And when I think of that, I think I've spent most of my career trying to teach the skill of lifting weights to my clients for a long time. And if you were, if we looked at this like a skill just like an athlete is learning their sport, whether it be basketball or soccer or baseball, you, what you wouldn't do is constantly be throwing different skills at them every single day or multiple things in a day. You would, you would focus on one thing and you would stick to that until they got really, really good at that. And then you would move on to the next thing and stick to that until they got really, really good at it because there is the learning curve of the skill of the movement, which I think later on plays a, that's why those studies I think are a bit flawed because if you take, you know, if you take the three of us who've been lifting for a really long time and we do something that's daily, you do something that's every three to four weeks and then you don't change it at all, I think it would confirm what those studies showed. But if you took somebody who, you took thousands of people to your point, Sal, that have, that are really still learning how to squat properly into deadlift and do some of these movements and would it be better for them to stick to that squad or stick to that deadlift for four weeks consistently versus squatting one day, then doing Bulgarian squats another day, then doing lunges another day. Oh, that for sure, yeah. Right. They're barely figuring, each one of those movements are extremely difficult in themselves and to be flipping them all the time, I don't think you're giving yourself the opportunity to get really good at the skill of it.
