Everyone says that keeping you knees in line with your toes keeps you knees healthy and works in favor of the bodies structures.
So my question is
How do the positions of the elbow and wrist/hand affect each other and what is position that hands down works in favor of the bodies structures?
I always thought that the healthiest position for the hand to be in relation to the elbow was to have your thumb be opposite of the direction your elbow is pointing in. Example. hammer curls, rope extensions, Neutral grip pullups and hammer grip db bench. And the worst being fully pronated due to the nature of the bones of the forearm.
