i knew this guy who couldnt squat for shit, he would forever lose his balance and he could barely get down to parallel. but one day i had him do front squats and all of a sudden became the king of squats....i guess he just wasnt use to the weight on his shoulders, so i pushed him forward and threw him off balance....with the front squats it makes you keep your back straighter, and you kinda have to or else the bar will roll of your arms...anyways try front squats, with just the bar and slowly add weight with time...
