Purpose: Make hitters vary their attacks and play to increase their arsenal of shots.
How it Works: 6 players set up on each side of the net. Create parameters for what the attackers and setters have to execute: For example, the hitter cannot play along the same "route" (or hit the same set) two times in a row. Have them run standard sets, quick plays, and faster sets. The receiving side gets both a service ball and a free ball to play out. After every point, switch the hitter who must hit the different "routes."
Requirements: At least 12 players, a full court, balls, and a coach.
