 Question is from I hate Matt Vincent. Is it true that if you don't use it, you lose it? Yeah, I think he was trying to be funny here, but it's true. This is one of the oldest lines in the fitness industry, isn't it? Well, didn't I bring this up on one of the most recent episodes where I kind of freaked out when I jumped out of my truck? Did I bring up one on the show? Did I talk on the show or was I just talking to you guys, I can't remember. No, you brought it up. Yeah, because, and that's a perfect example of, you know, it had just been a while since I had done any jump boxes or anything like that. And just out of habit, being in the back of a lifted pickup truck and then jumping out, it seemed like no big deal to me. But when I landed, boy, it felt way different than it had felt the last time I had done that. And I know that's because I haven't done it. I haven't trained that. So my body didn't absorb the asphalt. When I dropped down, I was in a more stiff position and I, boy, let me know all the way up my knees in my back when I did it. And I went, oh, shit. And that was an awakening for me that, you know, if this happens at one point in our lives where we just stopped doing certain things and we lose the ability. Yeah, and that's just to make us more efficient and effective with our energy and what we're doing. Like our body just recognizes what our biggest, you know, patterns are every day and, you know, how to allocate those resources in that direction. So it's like, it's this pruning system it has already. Like, okay, so if we're not doing this, let's go ahead and shuttle that, you know, attention in this direction because you're doing this more frequently. Yeah, your body is always trying to get just as good as it needs to get. It's never going to try to aim to exceed what it believes to be the bare minimums. And how does it determine the bare minimums? Well, off your activity and the signals that you send your body. Now, why, right? Why won't your body get stronger than the bare minimum that it thinks it needs? Or why won't it get the more agility than the bare minimum that thinks it needs? Because all of those require energy, just like Justin said. And our bodies evolved for the most part during, you know, for most of human history, energy was hard to come by. It was scarce. It made no sense. If your body became inefficient, you starved. It made no sense whatsoever. So your body is not going to be good at jumping. If you don't jump, if you don't ever jump, you lose that ability. Your body's like, we don't need this. We don't need the skill. Let's get rid of this and become more efficient. If you don't run, you'll lose that skill. If you don't ride your bike, you'll lose that skill. If you don't lift weights, you start to lose strength. This is true for anything at all. And even your ability to handle stress, to deal, it's funny, I grew up in a loud house. It was relatively chaotic at times, big family, loud, stereotypical Italian people. And growing up, it was just the way I live. It's not a big deal. If I needed to do homework or do something or whatever, it didn't bother me. I didn't even notice it. Moved out. And then I lived in a quiet environment, lived by myself for a long time. Then I'd go home and I'd be like, I can't handle all this noise all the time. Too much stimulus. Yeah, it's just like anything out, your ability to handle temperature, absolutely. So if you wanna maintain abilities, you have to practice them. There's absolutely nothing. And this is a very important lesson for people. It's like oftentimes we do the stuff that's needed to get us better, but then we forget that whatever we did to get there is what we need to do to stay there. It doesn't stay. Your body never stays. It only adapts. And so when we first, this is one of the oldest fitness sayings. It's been around forever. It became a parody for a long time. You don't use it. You lose it. I think it's been around since maybe the 70s and 80s, but it's almost the most true famous fitness saying. I can't think of one. No pain, no gain is the other one. That one's a lot of that's false, but you don't use it. You lose it. Totally true. And you could take this to the extreme. You could literally put your leg in a cast. Don't use it and do that for a year and watch what your body does to your leg. It starts to get rid of it. It's crazy. So absolutely, if you want something, you gotta maintain it and you gotta maintain that practice. Otherwise your body will just get rid of it.
