Can anyone teach me how to whip in handball

Whip
A way of hitting the ball so that it is not simply slapped back to the wall. Instead, the player will put his hand in a cup shape so that the ball just glides off of his hand. An integral part of the hook serve. It can also relieve some of the pain that one would feel if simply slapping the ball. It is suggested you whip the ace ball in order for it to hurt less when you hit the ace ball.

do not just hit the ball back to the next person in line. Use angles, different speeds of hitting the ball, and anticipate where the ball is going to go.

when the balls rolls out of your hand it has a sideways spin and will come off the wall straight but then after the bounce it will go sideways. It takes practice but is very effective up front

Smack, and while doing that, try to pull the ball.
