Backhand topspin

Hello I practice the backhand topspin movement and when the game start the movement i have practicing i can't make it but i do a movement different and the ball don't hit the table.

What can i do?

Hi David,

This is one of the progressions of learning a stroke.  You are on the right track.  Now you just need to keep practicing it more so that it becomes even more natural and you will be able to use it in a match.  Start by getting yourself to play the stroke in a match where you know the result, so against a weaker or much better player.  Then you can start to use it against closer opponents.

This is the way that we progress our skills.
