I've been doing full squats for some time now. First it was hard to go below parallel. I lost my form in the bottom. I trained squatting without weights for some time untill I got it right.
I used to have some lower back aches but squatting and deadlifting have strengthened my back, it was probaply just weak muscles. I have a thing about my knees though that concerns me. Although I never experience pain my knees make a *pop* sound often. What could this be? Jumpers knee?
I had the same popping knee issue a while back. I did not experience any pain or discomfort.
It was explained to me that it's just nitrogen balls popping and it's OK as long as there is no pain or discomfort. It was explained to me on this very forum by a very helpful contributor Scott Ismari. He seems to have disappeared :(
