A server lofts or crosses balls into the box at varying heights; the striker finishes first time on the volley or half-volley. Start with half-volleys off the bounce, then progress to full volleys out of the air. Keep the strike down and on target. Serve from both sides and rotate.
Fork it into your private drills, then change the animation, adjust positions, swap equipment, or drop it into a session block.
