Volleyball Drill Demonstration
Place a few balls on the baseline and spread them out. Players move in and out between the balls, moving as if they were in defence. Make sure players avoid contact with the balls.
This exercise masters footwork skills and the ability to change position quickly in defence.
If you want players to work harder, you can add more balls so that they are turning quicker, or alternatively, have less balls so that players take short steps and control balance.
