STEP 1
Harness the racket’s power.
Use a “continental” grip: Hold the racket like an ax, with the face in line with your forearm. Move the heel of your hand to the base of the grip, with your pinkie on the bottom of the handle.

STEP 2
Align your body.
Stand with your feet shoulder-width apart, your dominant foot parallel to the baseline and your other foot angled 45 degrees toward the line. Place slightly more weight on your dominant foot.

STEP 3
Don’t overtoss.
To create forward momentum, toss the ball to an apex 6 to 8 inches in front of you, and 1 to 2 feet higher than where your racket would strike it. Don’t throw higher and try to hit it on the way down.

STEP 4
Smash it.
Bring the racket behind you in one big arc and strike the ball with the racket angled slightly downward, toward your opponent. Don’t bend your elbow or jump, and don’t take your eye off the ball. Follow through with your swing.
