Volleyball Drill Demonstration
Players stand opposite each other with a ball between them. One player throws the ball up, and the other tries to "nail" the ball to the ground with the top part of their hands.
You will fail to do this exercise successfully if you do not bend knees sufficiently. Doing so enables great footwork.
The higher ball is thrown the more difficult drill becomes. Doing it for the first time, ask players to throw just over the floor, then elevate trajectory.
