I am retraining my body to descend hips first rather than knees first thanks to the helpful insight you all gave me about a week ago. As for the variants, what is proper technique? I was doing Zerchers yesterday and I was breaking at the hips first, is this correct? I did overhead squats a couple of days ago and I had to break at the knees because the load has to be almost overhead. How about bodyweight/prison squats, do I break at the knees or hips when there is no load? All of this being said I have always broke into the descent at the knees and I go ass to grass. I have never had knee problems, nor do I want any. Any advice will be helpful.
