What if I can't properly squat? How can I overcome this? I've tried doing different squat stretch's but I just can't seem to squat..I'm always on my tippy toes.
I just submitted an article that deals with the matter (http://news.ycombinator.com/item?id=1652595). The short version: Practice. Hold onto something at first, if you can't keep your balance.
Take a look at your shins. Mine have a significant negative camber, curving out to about 10-15 degrees. Because this puts my feet a few inches forward of a normal person's, I can't rest in a squat; I have to actively lean way forward.
If your shins are normal, though, just work on the leg strength to control your descent, and the ankle forward flexibility required to shift your center of gravity the inch or so foward to compensate for going from the balls of your feet to the whole foot.
(I do recommend dry practice.)
