 Next question is from Grant Satterstwaite. If isometrics don't build muscle, what is their utility in training? Who said they don't build muscle? I know, who said that? Let's fix that first. Isometrics build muscle. All forms of muscle contraction contribute to muscle growth. Now some more than others, but that doesn't mean you only should focus on one because the others have no value. They all have value, but here's the value of isometrics. First of all, they do build muscle. There's many studies that prove that. You will build muscle with isometrics. Not to the extent you will with full range of motion training, but one of the benefits of isometrics is I can focus on a specific range of motion. If I'm weak at the bottom of a squat, I can really focus on that bottom position of the squat. If I really wanna connect to a muscle, isometrics really are effective at allowing me to connect to specific muscles. It's also not as damaging. I can go high intensity isometrics and it's not gonna require the same recovery that traditional kind of resistance training is gonna do. So isometric, here's the deal. Everybody's always asking what can I add to my routine to make it more effective? Now, so long as you don't over train, isometrics is usually one of the best answers. You can add isometrics to almost any routine. You'll take this much more recovery, but you'll get this much more in return. So yeah, in the irony, it's like it spans all the way from the very, very beginner to the advanced. There's benefits all the way across the board and it's kind of funny that they said that you don't build any muscle when, in fact, any muscle contraction, whether it's like eccentric, concentric or isometric, either one of those is gonna actively stimulate the muscle in order to produce some kind of an output. So it's gonna stimulate the muscle, it's gonna affect the muscle, which in fact, if you do them enough times, it's gonna help them grow and develop as well. But yeah, isometrics, I mean, I think it's just because it's just not as popular, not as familiar, it's not as sexy. People don't like to focus on that portion of contraction very often, but there's so many other benefits to it that gets you really connected to the central nervous system. It actually acts as a way to alleviate pain almost instantaneously, which is a very amazing feature of it. And then building muscle, of course, is another huge part of that process. Well, I think it's because in the moment, or initially, if you compare it directly to the eccentric or concentric portion of the exercise, it doesn't build as much. So I think, and I say that in the moment, meaning like, you know what's that thing that you and Jessica always say, Sal, you're type one fun and you're type two fun, you have fun that is fun while you're in the moment, like think of that like- It feels like more work. Yeah, and then you have like type two where it's like you get added benefits later on. Like that's how I think of like the isometrics. The isometrics may not feel like or does not seem like you are building as much muscle as full range of motion exercises in the moment, but it has this great carryover later on to the points that you're making Justin right now with like CNS. Like your ability to contract like that, get a stronger, better contraction, recruit more muscle, will only in turn make you better at your full range of motion exercises later on, which will only make you build more muscle later on. So not training it because you think it doesn't add as much muscle or build as much muscle as a full range of motion exercise, doesn't mean that it doesn't have tremendous benefit. This is another example too of how studies can suck sometimes. If you took a study that showed these people only did isometric contractions for six weeks, these people only did concentric, these people only did a centric, which one built the most muscle over the course of 16 weeks? And you're just looking at size or something. Yeah, you're gonna look at your, by itself in a study for six to eight weeks, you're right. E-centric and concentric full range of motion is going to probably beat out for total muscle gain than the isometric. Yeah, but the isometric still built muscle. You know, when you have all three contractions, concentric, which is the lifting, right? E-centric, which is the lowering and then isometric, which is this, it's not moving, but you're contracting hard, either pushing against an immovable object or just doing it intrinsically. If you compare all three, eccentric builds the most muscle. Second place would be concentric, third place would be isometric. But what we don't, what people forget is they all built muscle. That means if you add them to each other, you get this cumulative effect. It's a compounding. That's what I'm saying by that, right? So it's like, even though in a study like that, if we're comparing, you go, oh, well, I'm not gonna waste my time with that one because it's the third most beneficial when it comes to building muscle, but that doesn't tell the whole story of what the carryover you're getting from training. By the way, bodybuilders have a long history of isometric training. In the 70s, Arnold used to talk about doing it to sharpen and harden his muscles. Bodybuilders today still do a lot of isometric training. Now they don't talk about it in their workouts because they don't consider posing as a part of the workout. But bodybuilders are posing constantly, especially before competition. What is posing? It's all isometrics. And by the way, for people who are like, oh, posing is easy. No, it's not. When you're on stage and you're doing a front double bicep, you don't just flex your arms. You are contracting and controlling everything. Strongman's a better example. Even better. Right? I mean, they gotta carry objects in an isometric position. I mean, they're moving with weight a lot of times. But also, too, they have events where they're actually just holding on to really heavy objects that are pulling them apart and they have to squeeze as hard as possible. There's lots of events centered around just if they can keep their position intact and strong in that position. So isometrics play a huge role.
