I've been given two conflicting pieces of advice and I was hoping someone could sort it out for me. After breaking parallel on a squat I sometimes have a tendency to "bounce" back up to start my ascent. I was (unsolicted) advised that bouncing like that is "cheating" and I will tear up my knees doing it. Well, I got worried about it and focused on coming up slower which is MUCH harder. I find myself getting stuck at the bottom and really having to push to get up. So I asked a friend about the bounce and he says It's not that bad for me after all and it's part of the technique of squatting. So who is right? I don't think the bounce is going to hurt my knees, if anything I feel it more on my hips, but I don't want to "cheat" at squats.
