Warm up through a hands-only support game: throw, catch and move to create space, then time a run to head a throw into the goal.
Ball moved by hand only, thrown and caught, no more than a few seconds in the hands and no running with it. Score by heading a team-mate's throw into the goal. Play one team combining to a header, or add defenders for a game. Encourage constant movement to get free for the throw and clever runs to attack the cross. A superb opener that warms up movement and heading together.
Fork it into your private drills, then change the animation, adjust positions, swap equipment, or drop it into a session block.
