 All right, remember what I said about not being excised police? Now, don't do this exercise. I forget that. This, the example I mentioned, college football player doing barbell step ups. And he either stepped off at the end of the set, twisted his ankle, dropped the bar damages fine, or he had the bar here, he turned around to bring it back to the rack and the thing. He lost control of it and then injured his spine. One of those is what happened. He injured his spine, came back to play and walked again. OK, but since I wrote congruent excise, another college football player stepped off backwards, injured his spine, and is paralyzed. I don't know what benefit this exercise has compared to other leg exercises. And it looks like a pretty simple picture. But other than getting off and starting excise, other than ending and starting excise, it's fine. So here's the problem with this. This implies that he steps up on the bench and stands up perfectly erecting on top of the bench. But if you try to stand up a bench that high, and I'm perfectly standing up here and I get my foot up here, I can't stay vertical and get on the platform. I and everybody else has to bend over to do it. Only now, like when you bend over in a squat, you have two feet as a base. Only now you have one foot as a base. So unless you're using a step, like a regular conventional architectural step, you can't get on top of the bench without bending over with the barbell on your back on one foot. So you have this load that's extraordinarily wide, and now you're bent over on one foot. It's amazing more people don't get hurt doing this. And now, so now, OK, so you do that, you live. And now you're on top of the bench with the bar here. And you're locked out because your thighs are gassed, your breathing heavy, your back is tired. Now what do you do? There's no rack over here. The rack is back there. The rack's not in front of you either. So what do you do now? Well, ditch. But what do you have to do? You're gassed, you're gassed, your quads are burning because you just did 20 reps or whatever. And now somehow you have to balance on one foot, reach back behind you for the floor. Again, the fact that more people don't get crippled on this is what's freakish, not the fact that some guys do get hurt. So if for some reason you think stepping up has some value beyond the work for the glutes and quads and et cetera, that's why running stadium steps was a classic exercise, right? They weren't too steep. That's why steps in a house or in an office are a certain height. You can pretty much do it with all hip and quad action and not make it more complicated. The best manuals and exercises are written. So please let me welcome to the stage Bill de Simone. So you'd be a champion, but it would kill you. Would you take it? And methodology aside and whatever the quibbles people had aside, a lot of people said yes. So that type of thinking, it's not just CrossFit. It's been around for a while, a boxer, a tennis player. The reason why you don't twist is the disc is between the vertebrae. If you twist the vertebrae, it's like bringing out a dish towel. And again, it allows it, but it's not the best thing for it over time. Your office are a certain height. You can pretty much do it with all hip and quad action and not make it more complicated. Also from the 2000 NSCA textbook. Same exercise, different parts of the book. OK? And neither part of the book identified one of these as the wrong way to do it or a risky way to do it. Perfect, but if you aim for perfect, then the natural, if you fall short, you still have a lot of margin of error.
