A defensive dig before a push into the air and then sets across the net to player 2.
For dig: Knees bent and legs just wider than shoulder width apart. Eyes on the ball to the point of contact with wrists, ensuring wrists are together. Head level with the ball at point of contact
For set: Eyes up looking at ball trajectory, with knees bent, and standing on the balls of your feet. Bending the elbows and pushing through the ball with fingers at point of contact.
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.
