Legal Serves

I am an advanced table tennis player thanks to your videos. I have trouble trying to not do an illegal serve. The only illegal serves I do is the throw back serve which generates extra spin, and have trouble trying to stop doing it? Can you help play by the serving rules and resist this throw back illegal serve? :(

Hi Jason,

Practice just the throw up of the ball to start with.  See if you can land the ball on a sheet of paper placed near your feet.  Once you an do this you know you are throwing up up quite straight.  Then add in the swing of the serve and see how it feels.
