Understanding Tennis

one way to preset the wrist action on the serve is to put the racquets face to the sky on your start

run around the forehand– play big

on the serve the hit is up and out 

thumb up rest of fingers make a 4 on the tossing hand

know where the ball is an  your partner

on the serve you could have a feet apart stance

on the two handed backhand get both elbows up on the follow through

many different starts– here is a full drop

attack the second serve

to get the big drop down on the serve motion your wrist must be loose 

on the two handed backhand get both elbows up on the follow through

get under and hit up

after the serve try and hit a run around forehand

hold the eyes and the head slot a beat past the hit

 to facilitate the kick serve have a big arch and toss more to the left–to help the hitting up
