You touch the ball with your fingers instead of your palms. "Beating" dribbling means that the palm of your hand is empty and your fingers bend downward according to the height of the ball. It depends on the joints of your palm, so you must bend hard. The other two joints of your fingers must not bend, and all your fingers should work hard together. Racqueting is very popular with children.
The basic essentials of children's racket movements are that the muscles of forearm, wrist and back of hand will lift the racket in coordination with each other. When the ball bounces off the ground, the hand should naturally lift the ball buffer and then take the racket down.
