I'm in my 8th week of StrongLifts 5x5. I started light with my squats to work on form (never really ever committed to squatting in the gym before) and now that the weights are starting to get heavy for me I was hoping someone could critique my squat form and offer up any tips/advice. I have a few videos below; the first two are from a few weeks ago (squatting 170 lbs).
The last video is from last week with a heavy weight for me (215 lbs). My concern in the last video is that my butt is starting to shoot up too early out of the hole and my squat is becoming a good morning. Any thoughts?
