How to perform it

Feet hip-width apart, ball held at chest height.
Reach the ball overhead and rise onto the balls of the feet — full extension.
Slam the ball straight down in front of you, folding at the hips and driving through the lats.
Pick it up and reset; a slam ball that does not bounce is the right tool here.
