I have quite a few structural issues that affect how well I can squat (pronated feet, one leg slightly shorter than the other, and scoliosis). As a results, I have really struggled squatting at a decent depth. In the attached video, I believe my depth is ok (please correct if I am wrong), but I'd like your collective opinion as to whether or not there is anything unsafe about my form. I don't believe I see any buttwink, but I could be wrong. Do I lean forward too much - I am trying, as best as possible, to remain upright (olympic style). Any tips for improving form would be appreciated.
