use the non hitting hand to guide the shot in– and prevent opening up too soon
place the racquet face to the ground–as you come out of it you will get more racquet head speed
on the serve get big
at times you have to hit it–no time to run around
to get the toss in front lean in
attack the serve by getting inside the court
breathe in and exhale by puffing your cheeks out
slight lead with the the bottom edge of the racquet
racquet dipped almost to the ground
keep the tossing arm up a beat and sight the toss through that hand
expand the court with a short angle
on the knee bend you should have a straight line of arc
on the serve have a preparation ritual–some like a across over dribble
try to save a shot over your head
