How do I get back a fast serve?
The best way to get a fast serve is to block the ball. You have to think of standing at the net and having to block or stick your racket out to just presented in the way of the ball. the method reduces backswing which allows you to get the racket face on the shot and the power the server will have it rebound back over the net. the power will do the work for you. The challenge is to read what side the serve is going too.
