Technique: Jam one end of a barbell into the angle between the wall and floor. Grip the other end with a hand above the weights. Start slightly squatting, with the barbell at shoulder height and your arm at a right angle. Explode up through the legs and shoulders, extending your arm, pushing the barbell away.
Set-up: Mark out a square using four cones. In one corner stands a defender, in the other stands an attacker. Starting without the football, the attacker tries to side-step the defender and reach the scoring zones. Try to suck the defender in and at the last possible moment, drop your shoulder and explode in the other direction. Progress drill by introducing a ball.
