This drill can be used as a base for a variety of attacks
Player 1 (acting as an opposition player) serves to player 3 who defensive digs to player 4. Player 4 sets the ball to player 2, who will have made an attacking run to meet the ball and smashes 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.
