i started snapping the wrist on my serve tonight after i was getting whooped, and my serves were not going in, and well the speed and placement where ten times better,,,, i watch this instructional video with the bryan brothers and brad gilbert and they did this drill where you really snap your wrist when you serve and serve it into the ground on your side of the court and see how far the ball bounces onto the other side of the court,,, now i heard if you hit up into the ball you automatically snap your wrist,, so am i doing it right or wronge?
