I'm on my second week of 5/3/1. This video is of my final 3+ set @ 290. The last two reps my knees begin to cave slightly. I actively work on pushing them out.
Its not a super low bar squat, but certainly not high bar either. I've noticed that I sometimes slightly rock forward out of the hole. To remedy I try and focus on rising up with the hips and not my chest/back.
Constructive criticism is much appreciated.
Thanks for your time,
