 First question is from Cole Rowe. Does flexing in the mirror have any significant carryover for mind-to-muscle connection? It sure does. Of course it does, right? No, you know it's fun. It must. If you look up the studies on isometrics, right, and the value of isometrics and how it helps you connect to muscle so you can fire it better, and oftentimes isometrics are done in these studies without any outside forces. So you're just flexing essentially, like what a bodybuilder would do on stage. And if you look at the old-school bodybuilders, this was actually a part of the routine. I know Arnold would talk about posing for an hour a day, something like that, pre-contest before the show, and he said it would bring out definition and quality, he said, to his muscles. This 100% has value. So yes, there's definitely an ego portion, where you're flexing in front of the mirror. But I tell you what, if you know how to hit, here's a good example, if you know how to hit a good back pose where you can activate your lats and flare them and flex them, it's going to be much easier to feel your lats when you do an exercise like a row. Well, this is how I teach if there's not any good solid connection, my muscle connection there in the chest even, like I'll slow it down and just pause in that position to squeeze and gain that neuromuscular connection, because it's so valuable that way, because when you slow down and you're able to kind of feel your way to activation of the muscle, that isometrics are beautiful for that. I always wonder when I was competing, if that was like the origin of it, right? Like if somebody actually really had the smarts to know that what he was doing or she, if it was a girl that was starting to do this first, right? Like if it was, my intention was to fire the CNS, get better connected. That's why I'm flexing in the gym all day long. Or if it was really something that was more self-absorbed, I like the way it looks. I mean, I always wondered that. Now I know that- Chicken or the egg, huh? We talk about this a lot. We talk about the importance of the central nervous system. We talk about being able to be connected to a muscle. If you can with no resistance flex every muscle in your body, I guarantee that you can train it better than someone that's control. Yeah. So that is a fact. So there is extreme value there. If you can on command, if I can look at you say, Sal, flex your right pec or squeeze your left flat, if you have the ability to just like that, flex or activate that, I guarantee that you have a much easier time building that muscle inside the gym. Totally. Now to answer your question, it was the isometrics that came first. So tension-based exercises have been around as long as we've known about resistance training. It's been practiced for a very, very long time as a way to improve strength and performance. Later on, bodybuilding included a posing round. So what they actually used to do in these shows is you would come out and do some kind of a feat of strength, usually involving gymnastics or some kind of a strongman event. Then there was a second round where you came out- They should bring that back, by the way. Yeah, right. Do you imagine these 300-pound bodybuilders doing some kind of like- Yeah, do something cool. Some of them can though. Some of them can though. You're right. Most of those are like, that's genetics though. Some of them just are flexible in others. Well, Flex Wheeler, man. He would do like he got my splits on stage. Tom Plats was known for his incredible flexibility. Yeah, but anyway, there's definitely value to it. And what's funny is the bodybuilding poses, the compulsory bodybuilding poses, actually, if you do them right, are excellent at activating pretty much every single muscle. Every single muscle, you have the front double bicep, the back double bicep, the front lat spread, the back lat spread, you have the hands around the neck ab pose, which is actually more of a quad pose, most muscular. All of the poses that you find in bodybuilding, even the rotating ones, which are compulsory, they're excellent for connecting muscle. Well, even before bodybuilding, you had Charles Atlas, and you had his whole program that was bodyweight based, but it was all just isometric flexing, I mean, for the most part. This skill also gives you the ability to change exercises. So you can do an exercise to one person may look at and go like, oh, that's for your traps, or oh, that's for your rear delts, and you can actually change what you're trying to focus on because you have that ability. Totally. Like when I go into an exercise, I can take the same exercise, and it could be something that was designed for my rhomboids, but I could be using it for my rear delts, or you know, you could be doing something that's like a major back exercise, but you're really trying to isolate and focus on the lat. So you can do movements that are traditionally for something else, but then work. I mean, just like a close grip bench press, right? When you are trying to work the triceps, you can really make that be more tricep than chest and shoulders. But if you don't know how to think about that while you do the movement, it becomes a lot of chest and shoulder still, it's still a chest and shoulder movement because of what you're doing. But if you have that ability to contract and flex the tricep on command like that, because you've practiced that, then you can go into a movement that, yeah, it has chest, shoulder and triceps, and you can make it more triceps like you're trying to do. Yeah, like how about a supinated grip chin up? I can make that a back or a bicep exercise. Like big time bicep exercise. Yeah, I'll tell you what, when you look at priming, like we talk about priming all the time, priming really is a much more individualized, advanced, and effective way of just connecting to muscle. Flexing, essentially, is what priming is if we were to make it really, really general. So definitely there's a value to flexing. In fact, especially if you have a weak body part, flexing it in between sets and at the end of your workout should make a difference. Well, that's all resistance training, is flexion of the muscles with some sort of resistance. That's all it is. You are flexing a muscle and that resistance can be weights like barbell stuff, it could be cables, it could be bands. I mean, that's all resistance training really is, is flexion of the muscle with some sort of resistance.
