Andy,
If you are trying to throw a baseball as hard as you can, when you start to wind up is the ball farther from your target, or your elbow? This should be a clue.
And what about his right foot? Is that further away from the target - I think not.
- from Kevin, with the apparent agreement of many of you who are more “athletically” blessed than Andy - "Everybody who throws a ball steps on his rear foot to get the movement started."
No one steps backwards in order to make a throw - period. The action of drawing the throwing arm back promotes, like in a golf swing, a pivoting motion whereby the weight shifts onto the leg furthest away from the target. The leg, itself, does not shift.
The pivoting back towards the target whilst, at the same time, engaging the arm in the throwing motion, gets the job done.
Anyone see a baseball player step backwards prior to throwing the ball?
Does'nt happen does it. It is simply not necessary, unathletic, and wastes valuable time.
PS:
I played Cricket all my life, regularly throwing the ball flat and hard from 75 yards, or more, so I have a little experience of the subject.
