I didn't have any problems with my back rounding, but it could have been because I wasn't using enough weight. When I got to the bottom I was able to explode up pretty hard...and I kept my posture good when I got there.

I'll try to get a video up soon. It looks like I'll be lifting in the basement at home for the next month. I have a squat rack, a bench, and a 300lb weight set. I can't bring myself to pay for a gym membership for a month because I'm so used to going to the gym for free at school.

I guess the one good thing you can say about the guys at the gym doing squats is that.......they're doing squats. I never have a problem finding an empty squat cage at my gym. Now if only people would stop doing bench press...
