Understanding Tennis

hit in front of your body

at a different height Draper still dips below the incoming shot 

angle out the tossing arm

get the back knee under the incoming ball

on the volley breakout  with the racquet head above the wrist

when you have added a one handed backhand early decide when to use it 

cover the short shot and angle off the hit 

compact high pull back on the serve 

square up the hit point

get under and behind the incoming ballon contact

if you can stop the lob going over your head you are better off court position wise to go for it 

on the serve get big

to get the racquet drop on your serve you must have a very loose wrist
