Instructions
Hold the racket with the handle pointing toward the hand you hold your racket with. Face the webbing perpendicular to the ground.
Spread your thumb and first finger to make a V. Place the racket handle in the space between the two. Wrap your remaining fingers around the grip of the racket handle, keeping the racket handle out of the palm of your hand.
Place your thumb straight down on the racket handle. Curve your first finger around the grip so your knuckle is against the grip.
Move your hand so the raised lip at the bottom of the handle sits right where your hand ends and your wrist begins. Rotate the racket toward your thumb about an eighth of a turn, just enough for increased power during a smash.
Hit a shuttlecock with the new smash grip to test it. Adjust the amount of rotation until you find the best location for your smash.
