Points to look for:
- The shoulders have continued to turn back towards their original position.
- The bat has continued moving upwards.
- The player is watching the progress of the ball closely.
- The free arm is still stationary.
- The ball is bouncing over a foot inside the endline, since the player wants to the ball to bounce twice on the opponent's side of the table. It can be difficult to double bounce the serve if a lot of topspin is put on the ball.
