note:i tore my ACL over a year ago and got surgery in december of '09. i didn't start doing heavy squats until after my surgery so i'm not sure if the two are related but figured it was worth mentioning
i've made a good amount of progress squatting over the last year (went from 135 to my current 1RM of 315) but with heavy weights i feel like i'm "wobbling." it almost looks like i'm shaking my ass left to right or something as i go down. have any of you had this problem before? i'm worried that i'm really deficient in some area and i'm going to end up hurting myself down the line.
