How does Jan Ove Waldner serve

Hi, I just wanna ask about Jan Ove Waldner and his serving strategies, where he always changes his serves frequently with a lot of spin and speed. He makes the ball look like it has a heavy topspin but it came as a strong backspin. How does he really serve? Maxwell

Hi Maxwell,

Waldner has some special skills.  The one where he serves the Pendulum serve that looks like topspin but it is backspin, he moves his hand down while lifting his shoulder and arm.  So the bat is hitting the ball downwards while giving the impression of topspin.

I think a good way to improve these serves is to watch him serving many, many times.
