Welcome to the inform fitness podcast rewind, our listen back to classic interviews with high intensity gurus, scientists, and authors. This is part two of four with author and personal trainer, and biomechanics expert Bill De Simone. Bill is certainly known for a sensible biomechanics approach to exercise and training, and that it should always be joint friendly. Bill and I are going to be talking about the importance of always using a safe and limited range of motion. Bill and I both agree that everyday life tests us and can in some cases, certainly push and extend our safe limits of range of motion, especially in sports. So later in the episode, we will be talking about should you be working out to extreme ranges of motion if your life or your sport asked forBill DeSimone 1:43 it. I'm saying limit range of motion because that might be the verbiage that we understand and maybe listeners would understand, it's really a lot more complicated than just saying use this range of motion. So for instance, in a low back exercise, a stiff legged deadlift, when I used to misinterpret that by using a full range of motion, I'd be standing on a bench with a barbell, and the barbell would be at shoe level, my knees would be locked, my lower back would be rounded, my shoulders would be up by my ears as I'm trying to get the bar off the ground. And so yes, I was using a full range of motion.Adam 2:20 And I go to a chiropractor just listening to that. Exactly,Bill DeSimone 2:23 yeah, but you still see it all the time. You see it all the time when people are using kettlebells. You see that exact posture, right? The kettlebells between their legs and knees are locked, the low back is rounded. And then now they're doing a speed lead, at least I was doing I'm slow. They're doing speed deadlifts. So if I was going to use it, if I was going to do an exercise like that, it would be a extreme range of motion, I would be looking use a correct range of motion. So for instance, I wouldn't lock the knees. And I would only lower the person's torso so that they could keep the curve in the lower back, which might require a rep or two to see where that is. But once you see where that is, that's what I would limit them to. So for instance, the chest press machine I have in the studio, so nitro andAdam 3:05 Nautilus, nitroBill DeSimone 3:05 Nautilus Nitro, the seat doesn't adjust enough for my preference. So the bed hurt the person's elbows come too far back. So first is to get the first rep off the ground, the person's elbows have to come way by way behind the plane of their back. So what So what I'll do is like, you know, I'll help the person out of the first repetition help out of the bottom, and then I'll have you the my hand or the clipboard where I want their elbow to stop. So as soon as I touch my hand on my elbow, they begin the other way. So that's another thing we tend to do is we tend to think of ...
