Assume ready position, as you would at the net. The hands are up and extended rather than down, as they are at the baseline.
Step2
Extend the arms out in front of you, keeping the racquethead below eye level (at chin height).
Step3
Be on your toes, and ready to split step.
Step4
Take your split step as your opponent makes contact with the ball.
Step5
Lay your wrist back so that the palm is facing toward your target area (your palm dictates the racquetface direction).
Step6
Step in with your left foot (for right handers) as you make contact with the ball.
Step7
Keep your hand, wrist and arm firm during contact.
Step8
Block or punch the shot, using very little racquet motion. Since the ball is coming much quicker, a swinging or waving motion is rarely needed.
Tips & Warnings
Practice either close to the net with your partner by keeping the ball up in the air. This will quicken your reflexes and develop good volley technique.
Practice off the wall, approximately eight feet. Keep the ball up on the wall (i.e. don't let it bounce).
