Squat:
Sicne Rip and I will never see eye to eye on the issue of hip drive and such (e.g. I think you're GM'ing, esp towards the end of teh sets), I'll make these comments:
1. I think you would benefit by bringing your stance a touch narrower. Your knees break in a bit in the hole and you'll find it easier to get depth by bringing the in a touch
2. Slow down your eccentric. This is especially noticeable on the side view but the momentum you're carrying into the hole is causing you to round your upper back and get tipped forwards/cratered at the bottom (and this is part of what's contributing to you GM'ing it up). Slow down, fast up.
DL:
1. YOu might want to drop your hips a bit more at the start. I think youll find taht you get better leg drive by doing so.
2. As the weight gets heavier, your timing gets FUBARED. Watch the last couple of reps at the heaviest weight. You start the bar off the floor, lock your knees out without hte bar really moving and then SLDL it up with your low back.
