I was playing pool today I decided to notice how people crouch down (to get the balls). Well, without fail every single person keeps a perfectly straight back and sits back on their calves...and raises the heels.
Is raising the heels a bad thing since it seems to come so naturally to everyone (especially when performing a manipulation in front of the body)? It definitely feels a lot stronger and more comfortable than staying on the heels.
Just curious what the thoughts are on this. Maybe each has its merits.
