1) This drill involves a number (a minimum of three) of players standing on the baseline as if ready to serve, with a player standing close to the centre of the net of the receivers side (acting as the setter).
2) Players take turns to serve to the player opposite them on the other side of the net.
3) The player receiving the ball then digs the ball to the player by the net (the setter). That player then catches the ball and rolls it back to the server.
In this exercise part of a team works on accuracy of serve while the other improves receiving skills.
It is easier to place the ball crosscourt as its way is longer than down-the-line (this is in case the player hits the ball too powerfully).
Receiving players also have more time to react to the ball when awaiting a crosscourt serve than facing him/her down the line.
Ask the player to take more powerful serves and to change direction of the ball.
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.
