One player stands near to the net with another player next to them feeding balls in. A receiver stands in zone 5 and digs the balls that are spike to him quickly.
Receiver needs to stay focused to dig the ball towards where the feeder is located.
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.
