Players are given a free ball. They must back off the net, and give a good pass to the setter. Whoever passes the ball up to the setter will then get set up. They must work on their transition to hit, and make sure that they have a good pass so that they can hit.
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.
