Head a high ball under control to a teammate. Meet it with a relaxed forehead, take the pace off, and direct a soft header down into your partner's feet.
A server lofts a ball to the header, who cushions it softly down into a teammate's feet with a controlled header. Emphasise a relaxed forehead and neck to take the pace off, and directing the ball down and accurately. Rotate the roles and vary the service.
Fork it into your private drills, then change the animation, adjust positions, swap equipment, or drop it into a session block.
