Fadi do you know, that is exactly how I squat, in all 3 cases, and each time i have, people have told me not to lean forward at all, and to keep my back completely straight up vertical throughout the whole movement, it is nearly impossible to do so! and as for the levels to squat to, i have been told to squat so that my ass nearly touches the ground, there is a guy at our gym who can squat with his bottom only centimetres off the ground so apparently everyone is expected to squat like that. Thanks for that diagram, now I know i was doing it right! As for stance, i used to do legs just over shoulder width apart with feet slightly (and I mean only slightly) face away from each other, and this apparently was wrong too and several people at the gym told me to stand with them facing wider out more or completely straight to the mirror, which i found only added pressure to my left knee. what is your take on foot positioning?
