When I start to go heavy on squats I start to list(lean) to the right side. I'm pretty square up to about
275lbs. but when I put 315lbs I lean about 2 or 3 inches to the right. Also, my training partner says that when I start to go heavier that my ass seems to be moving a little to the left. This break down in form hurts my lower back on the left side at the SI joint area and the next day I can feel some nerve impingement in my left leg. Additionally, I have to stretch extensively between each set or the left side of my lower back gets real tight. Any pointers or suggestions from any squat experts would be greatly appreciated. As far as my stance I take a pretty wide stance with my toes pointed slightly outward - I use a box for one of my two weekly squat workouts and I always sit way back with my ass. I'm wondering if I have weak abs or a spinal injury-maybe a slightly slipped disk?
