Exercises with a throw-off or lead-off by the leader are suitable for technical aspects of training.
Teaching the forehand and backhand technique:
Exercise 1: the player drops balls and the leader holds the player's racket, so the player has to take a high loop, swing under the leader's racket and hit the ball to the other side.
Exercise 2: as above, but the leader leaves the racket as an aid and drops the balls again.
Exercise 3: the leader passes balls to the player, who must perform the same stroke sequence from the movement to the ball.
Exercise 4: the leader plays from the opposite side with the racket and the player performs the same stroke sequence (further distance).
