John Dunning shares a 4 vs 4 cooperative drill with three players in the back row and a setter in the front row. The objective is to get a rally where the ball crosses the net 10 times. You can adjust that number to fit the level of your team.

In this drill, players rotate every time the ball crosses the net from their side, so everybody gets a chance to set. To emphasize high quality sets, Dunning adds a rule that if the set isn't good, the score goes back to zero.

"Setting goals where if you make a mistake, you start over makes you a better player," Dunning says. "There are no throwaway touches."
