If the person under load is lifting too much weight the body will compensate. I don't need to go find an NIH study to convince you because I think you of all people understand this best. The core stabilizes the weight over the center of the feet. A weak core will cause the weight to walk over the toes in one direction or the other and the body compensates by diving back. "stay in your hips" in saying literally the same thing. Your core must remain tight. Many ego lifters crutch on a weight belt and a valsalva rather than possessing the core strength required for a lift. You cannot have one without the other. Stabilization originates in the core.
The "bow shape in the knee" exists and if you didn't see his knees nearly touching on rep 2-3 you're actually blind. This is yet another compensatory action that is a result of weak glutes and very typical of ego-lifting. There two ways to achieve maximal contraction of the quads and adductors. Your way, the correct way, with a wider stance and feet at 30 degrees. The other way is to stand too close, which causes the knees to buckle under the load. What physically happens during the knees buckling, rip? The quads and adductors have found the path of least resistance to achieve maximal contraction (at the cost of the lifters ACL). This isn't "bullshit". I don't need to draw a diagram for you. The application of force over a lever (the knee) can occur correctly or incorrectly. In the incorrect form the knees must buckle to provide the resistance. I'm not in the interest of drawing out the force diagrams especially because I'm positive at this point you're just going to troll me further.
In otherwords, as if by magic, my "bullshit" has reached the conclusion that OP is lifting too heavy and moved up too fast. It sounds like you're saying the same thing. Defaulting to bullying rather than correction isn't the most effective tactic. You deserve ample respect for the books you've written, but reverence in the face of being a dick is not deserved.
