The spiker begins by setting the ball to the setter, who spikes the ball in return. The spiker now digs the ball in the air to the setter, who this time does set the ball up for the spiker to attack and hit over the net.
In this drill, both the attacker and setter train ball control whilst spiking.
Ask players to spike over the net hitting targets (e.g. sideline, baseline, attack line).
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.
