Technique. -Use a medium stroke, your racket arm should move forward and downwards in the direction that the ball is going to travel.. -Your free arm should point towards the ball to assist with your body turn and balance.. Ball feeder tosses 5 balls in a row to athlete’s forehand (no bounce in the ball). Ball feeder tosses 5 balls in a row to athlete’s backhand (no bounce in the ball). 10 pts each ball between the service line and the dash line. THE BACKHAND DRIVE The arms are tucked in close to the torso. The upper body twists opposite of the throw as the front foot moves forward to the plant position.
