All formats of volleyball (2v2, 3v3, 4v4 and 6v6) can be played with similar rules while sitting on the floor and by playing sitting volleyball.
Further information on sitting volleyball can be found in the sitting volleyball section or by visiting the sitting volleyball England page.
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.
