Here are 3 Simple Progressions with the TopspinPro for Children & Beginner tennis players. Progression 1: use flat hand and feel the ball against the palm of the hand. start to brush the ball to get it rolling over Progression 2: use a choked up grip (hand in the middle of the racket) putting a finger through the V helps correct the grip and repeat the motion Progression 3: hold the racket at the end of the grip as normal. repeat the motion just feeling the ball with the strings.
