First, awesome work with your commitment to strength training and sticking with it and asking for feedback. Second, I am pretty sure your squats are substantially high but it is very difficult to give a proper form check with the current camera angle and movement. Could you film another set from a stationary view, from the rear at hip height and at and angle of about a 45 degrees?
Did the bar appear to be in the proper position on my back?
If you find flexibility an issue, give this a try:
I haven't seen such poor cinematography since the the Kim Kardashian sex tape, but you are on the right track.
Ideally, but these are really high, and you've spoken elsewhere about how heavy they feel. Don't wanna step on any coach toes, but I'd guess you're looking at a deload here.
I've checked out all your videos, and without getting into specifics (seeing as how you've had an army of coaches swoop to your aid, you lucky guy) it looks like you just need to get used to proper form being more difficult. I don't mean moving the weight, but getting into position. Getting the bar in the proper position is challenging and uncomfortable. Squeezing your chest up enough to set your back is as well. It's difficult before the weight ever moves. Sounds fun, eh? You'll get it!
