Throwing the ball up

Hi coach alois sir, i having a problem in the accuracy of droping ball. to improve the accuracy of dropping ball, what kind exercise that you suggest for me to do?

thx

Hi Rizky,

To improve your throw on the serve you can start by not using your racket but just throwing the ball up.  Put a piece of paper on the floor in front of you and then throw the ball up and see if you can land it on the piece of paper.  Once you can do this consistently then you can pick up your bat and try to serve.

If your throw becomes crooked again, go back to throwing it up without a bat.
