well, I was 220 at the time, all i did was power movements. had knee wraps and belt on. And it was more of, exploding up, than proper squatting.
Now that I use proper form, I go lighter. In order for me to squat that much with horrible shaky form and execution I wasn't doing much for legs.
I don't know if it makes sense... but when you do squats, do you press up with your arms too? When I do them now, I let the weight sit on my upper back and let me legs do the work, slowly. Back then, to get the weight up, I'd push with my arms while lifting with my legs, violent and shaky. Not sure if it makes sense. in retrospect, squatting that much with that kinda form was stupid and I wouldn't recommend it.
