This task will get your players used to receiving a serve and preparing in second fraction to dig up a spike from Zone 4 and Zone 2.
Player 1 serves from the opposite side of the court into zone 5. Player 2 (acting as a back row player) then digs up the ball.
Player 3 (standing close to the net in zone 4) then spikes the ball to player 1, who has to dig up the ball.
Player 4 (standing close to the net in zone 2) then spikes the ball to player 1, who again has to dig up the ball.
Be sure that the player in backcourt maintains a low position with relevantly bent legs.
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.
