been awhile since I've posted here, so here goes..I just want to know, how long should it take for a person to learn how squat 100% correctly?? since I started lifting roughly a 1 year and a half ago my squats been totally messed up. I've had to constantly go back to light weights to learn how to squat properly, because every time I start getting to heavier weights (between 80-90% my 1RM) my form begins to mess up and I
lean forward on my toes as I come up. I think the reason could be that I feel like I'm losing balance on the way down, so my weight shifts forward, rather then on the heels. Any way to improve??
