Set up as shown with cones on the baseline and the attack line.
Players start on the baseline and they have to run to the attack line and then return to the baseline. Once here, they then run to the centre line and then back to the baseline.
On the next run, they run to the attack line again and back, then to the centre line and back, and repeat this.
This drill is a great warm up for players as it gets the blood pumping and also focusses on starting and stopping. Repeat the drill a number of times and increase the speed.
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.
