Tennis Drill Demonstration
Coach stands in front of the player and throws the ball. The player moves left and right and catches the ball.
However, when the coach throws the ball, they shout "right" or left", and the player must catch the ball with this hand, regardless of what side of the body the ball comes to.
This is a great drill to work on reaction time and also to get a player to focus at the beginning of a session.
Coach should vary the throws to make the drills more difficult. Don't simply go "left, right, left right" etc. Should mix things up.
