One player serves or throws the ball from the other half court.
The receiver must overhand pass the ball to Zone 2 where a player will set the ball up to Zone 3 or 4, for the original receiver to smash the ball.
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.
