Cover the court alone and win the rally: read the flight, move early, take a clean first touch and return it with control or pace.
A small court with a central line, 1v1. One bounce allowed, two or three touches to return it over the line, score like tennis. With no partner the player must cover the court, so keep it small to start. Feet, thighs and chest only. A superb individual technical challenge and a competitive way to finish a session.
Fork it into your private drills, then change the animation, adjust positions, swap equipment, or drop it into a session block.
