Defensive players need a lot of concentration because they will be attacked twice.
Players pass the ball to setter and setter sets the ball to zones 4 and 2.
Players should aim the attack to zones 1 and 5 where defensive players are waiting to defend the field.
After the spike, defensive players have to pass the ball successfully to coach and he performs one more attack while defense has to do their job once more.
This drills requires good concentration, skill and movement. I suggest doing this drill with advanced team and not with beginners.
Coach throws the short ball and the player performs dig to stop ball touching the floor.
After the dig player stands up the fastest he can and moves back to position himself for good a defence.
At the same time, on the other side of net, player passes the ball to setter.
This drill perform players one by one.
Player in zone 5 runs to the net and performs block.
After that he runs back to play good defense.
Coach spikes from zone 2 and player has to defend and pass the ball into the basket.
After first player finishes the drill, next in line takes his place.
Coach throws a ball high.
Passer passes a ball to setter and attacks from zone 4 against one blocker.
Defensive players should cover the block, and save the ball touching the floor.
After finishing this drill couple of times, attackers should attack from zone 2, and later from zone 3.
Defensive players has the same job, as mentioned.
