How to make a powerful and reliable serve?
- lift up ball (not throw!!!): the ball location determines flat/topspin/sidespin
- V shape preparation (Stay at this position for a moment to reserve energy!!!)
- drop racket head by twist arm quickly (actually lightening fast)
- cut to the sky
- hit the ball
- pronation
- land in balance for following strokes
There are three key positions pros use:
(a) trophy position: body is in arc, hitting arm is relaxed
(b) arm twist position: racket head is downward, and keep in right side
(c) pronation position: palm facing out with high elbow
Here is the video to show "pronation":
