I have worked with a lot of people recently who are having trouble with their serves. This shot can be as complicated as you want it to be, but here are the Four golden rules that I used to build my service motion.
- Make sure you practice an accurate toss and leave your tossing arm up as long as you can.
- Make sure the racket never stops moving.
- Make sure you reach up to your highest contact point.
- Make sure your wrist comes over the ball.
