3 player triangular passing drill. Player 1 and Player 2 use defensive dig passes, whilst Player 3 uses the overhead pass. This can simulate player 3 setting up a teammate for a smash
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.
