To play a pure backspin ball is very difficult. The following exercise improves the feeling for this kind of rotation. It’s about playing a service, which bounces on your own half of the table, then on the opposite one and then again on the own one. This seems impossible at the beginning, yet is easy if you follow some tips: First you have to play the ball in a high curve and let it bounce on your own side very close to the net. The actual stroke has to be upwards and the ball has to be hit „on the back“. It’s totally normal that one simply does not hit the ball at the beginning. Sometimes the exercise can be accomplished with sidespin. At this point the coach is asked for, to remind the player, that the ball has to come back to him and not leave the table sideways. This exercise is perfect for a bet: After a while of practising the player has six tries, of which one has to be a „returner“. Though this kind of service is not suitable for competition – the opponent would run to the side of the table and smash the high ball – it is very good to get a feeling for much backspin.
