A very strong squat no doubt! 505 on linear is pretty f'ing amazing dude.
First two things I notice is that you start your squat with a knee wiggle, forward, back, forward. I don't know that i think it's a big deal, just an observation. Something you have no doubt been doing for years and do when getting set.
Your head is down between reps, and then pops up and stays there throughout the squat. I personally would like to see a little more hip drive, and I think that will come with getting your head in position.
I swear I watched the video 10+ times, sometimes I think a few of them are a little shallow, sometimes I think they are borderline, sometimes I think they are marginal. Tough to tell from video. They would pass an SPF meet, but you'd get 3 reds in the USAPL I think, at least from what I see in the video.
In the end, get your head in position and maintain that position throughout the rep, DRIVE your hips out of the hole and keep driving them.
I'm interested to hear what the other coaches say.
