Initial serving strategy could include the following objectives: serving to the weakest receiver in the opponent’s team; serve between two players; serving short; serving to the deep third of the opponent’s court; serve to the front-row attackers in the opponent’s team; challenge the strongest attacker to pass the ball, then attack.
Highly skilled players can control the ball on offense and attack at a high rate of efficiency. Strong, effective serves are needed to force an opponent to unpleasant situation, leading to a less successful attack from the opponent. At a lower or intermediate level, effective serving may require a high percentage of serves simply to be in play, since the opponent’s offense may not be powerfull.
For successful, consistent serves, practice serving for control and accuracy. Servers take the ball and serve to hit a target. For target you cauld use mattress or you can position some players, so the servers have to hit them.
Once you’ve mastered the basic service, it’s time to practice serving for power by accelerating the hand to the ball. Position the mattress near the endline. These mattresses provide a deep-court target zone for the servers. So, tell your servers to hit them with their serve.
