This exercise is the second progression in learning the X3 smash technique. After isolating the wrist movement without a racket, the player now reproduces the same action using their racket.
The objective is to transfer the movement of the hand to the racket, incorporating racket preparation behind the head, full arm extension and a follow-through with the wrist flexed.
This progression also helps reinforce the slightly closed racket grip and the contact point on the upper-left area of the racket face, encouraging the generation of topspin.
