Players stand on opposite sides of the net at the attack line. They shuffle across the court and set the ball over the net to each other.
This drill helps players adapt their body position to the ball trajectory, and this also improves footwork.
One player may set just over the net while the other can set high over the net.
New hitters rarely miss because of their arm. They miss because of their feet. Build a reliable approach, then time it with your setter.
When your hitter gets stuffed, five teammates standing and watching is how you lose the point. Good attack coverage turns a blocked ball into a second swing.
Coaches spend hours correcting arms in serve receive when the real fault is almost always the feet. Fix the movement and the platform fixes itself.
