The first step of the topspin tennis forehand progressions is to play from contact. The racket starts at your contact point and your body is facing the net. From this position, hit the fed tennis ball over the net and follow through. Make sure to catch the tennis racket with your other, non-hitting arm. This will help you follow through correctly. Because you are brushing up on the back of the ball, you should be hitting with a little bit of topspin.
