Players stand in pairs with a ball between them. The player starting with the ball spikes it to their teammate, who digs it back.
The receiver then spikes the ball again but this time, the digger must dive to dig the ball back, regardless of their distance to the ball.
Players should count every successful dig they do and compare with others. This improves communication and adds a competition element to the drill.
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.
