A 3 player drill which can be used for a variety of passing
Player 1 Overhead passes to player 2, who passes to player 3. Player 3 then defensive digs back to player 1.
Accuracy of passes are vital, and as players ability improves the distances between players can be increased.
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.
