A ball is placed 8-10 m in front of the player, or the player rolls a ball forward on the court.
Now the player runs forward and without stopping bends down and picks up the ball with one hand.
The arm is brought backward and the ball is flicked over the head and forward.
The run continues and the ball is caught up and is dribbled forward until the shot.

The exercise demands that the player at least is able to hold a ball downward with one hand.
