Ok first off let me start this post by saying... I have not been able to do squats in 5 years. My senior year of high school, I stretched the front 2 ligaments in my shoulder to double their size, causing my shoulder to come out when I do anything behind my head. i.e. Squats, Behind Head shoulder Presses/Behind the Head Lat Pulldowns(I don't do these anyway cuz I know how bad they are to go in the back, but these are just an example). Anyway I recently realized that since I had put on 40 pounds of muscle, I had gotten slow. I was the same percentage of body fat as I was in high school - 7-10%, but I had gone from running a 4.3 40 yard dash, to barely pushing a 4.5. So I decided to try and do squats. Anyway I get down in the squat rack just waiting for my shoulder to slide out once I mount the weights, and after the first set of 10@95lbs (just a test weight to see how the shoulder was) it didnt slide out, or even get hung like it was about to come out. I upped the weight, went to 225 still nothing. Upped it again went to 315 still nothing. Upped it one last time and finished the exercise at 365 and my shoulder was sitll wroking properly.
Now my theory is this... My traps had gotten big enough to where the bar didn't sit so far back on my shoulders causing the bad shoulder to be able to support it. Is this a valid theory? Or did my shoulder get strong enough to keep the joint inplace? Although my many anatomy classes seem to displace this theory. If anyone could think of a reason it stays in now when I do this exercise I would love to be informed of it.
ALSO - I KNOW EVERYONE HATES SQUATS, BUT YOU SHOULD CHERISH THEM AS YOU WOULD PROTIEN... I FORGOT HOW GOOD IT FEELS TO HAVE THAT WEAK LEG FEELING THAT YOU CAN'T GET FROM LEG PRESSES.
