Place 1 player at foul line, one player approximately in the center of the paint and two players at low post. Player at foul line passes the ball to one of the low post players. The player in the center of the paint first defends the ball until shot goes up, he then gets back to box out the other player at the low post and make the rebound. If he does not get the rebound he defends the ball until the shot goes up again. He again boxes out and goes for the rebound.
Keep the defender moving his feet
