Smash power: technique and kinetic chain

What this lesson covers

Increasing smash power relies on a relaxed arm and a proper kinetic chain rather than brute strength. A continental grip is essential, with the trigger finger loose to prevent excessive tension. The body should be in a closed stance with the back toward the fence, ensuring the left shoulder and left foot point toward the target to allow for full hip rotation. The 90-90 rule dictates the starting position, where both the elbow and the racket form 90-degree angles before the racket drops into the swing.

Power generation begins with the hips, which must initiate the movement before the arms take over. The cartwheel effect, involving a vertical motion with the non-dominant hand, helps create a downward trajectory and adds pressure on the chest for greater acceleration. Jumping into the ball can further enhance power through ground reaction force, provided the timing is consistent. A horse kick motion with the back leg helps maintain hip rotation during the jump. Hitting the ball high and slightly in front of the body ensures a cleaner strike, while a harder racket surface like 3K carbon and a teardrop or diamond shape can assist in generating more speed.
