I wish I could understand what he is saying

[@daigo5575]

- ball must be always in your body - keep moving and get into a good position ( ball in your body) - wrist must be stable, use your forearm. -action must be small, sudden and concentrated -hit the ball at the highest point -if it's a heavy downspin, you can brush the ball a little - after you hit the ball, your center of gravity must always lean forward
