An exercise for the attacker. The attacker has to be available for a second attack after a block.
First the middle attackers. At the net stand the playmaker (S) and a head blocker (1) ready to start blocking. Next to them stands the trainer (T) with a ball. Three defenders (4, 5 and 6) are standing at the back of the court.
Swap with the outside attackers on the outside position.
