Running through the ladders sideways with two feet in each hole then step out of the ladders each time
Keep knees kept low. Arms are at a 90 degree angle and elbows are going backwards and forwards
Chest up, core is kept stable. Go through twice facing different direction each time.
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.
