Rice University coach Genny Volpe demonstrates a coach-on-3 warmup drill here that emphasizes ball control and communication.
The players start close together, requiring them to keep a low base position and an extended platform. As the drill progresses, players move back to fill the court and must have continual movement and communication to keep the ball alive.
Volpe likes her team to warm up with this drill as a way to get both their voices and bodies moving.
