Start with players spread out and facing the coach in two or three lines. Have them begin in ready position dribbling in place with their dominant (Strong) hand while protecting the ball with their non-dominant (weak) hand. Move among the lines and check their balance, make sure their butts are down, backs straight and heads up (not watching the ball). When you shout "change" have them cross the ball quickly over to their other hand. Check their balance, stance, and head again.
