The optimal timing is very important for the forehand as well as for the other basic strokes in tennis. In this case, the best meeting point of the ball is in front of your body.
The distance to the ball must not be too big or too small. Tennis players often have the problem that they hit the ball too late, i.e. too close to their body. From there it is then difficult to hit a controlled forehand.
When contacting the ball, the racket head should be approximately parallel to the net. With the topspin forehand you hit the ball in a slight upward movement. You “wipe” the tennis ball to give it a forward rotation.
Also make sure that you hit the ball with the sweetspot of the tennis racket.
