PLayers start at '10 ft line' and serve 3 successful serves to partner.After 3 serves, each player steps back. This is continued in each spot until all players reach behind the service line and complete 3 serves from there.
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.
