Players 1 and 2 serve 5 balls each. Players 3 and 4 pass the ball to player 5 who catches the ball and rolls it back under the net to the servers. Servers should try and serve into the open court to make it difficult for the receivers
First look at the target before serving.
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.
