This is the position a player needs to have when positing up to receive the basketball.
The player needs a wide stance, knees bent and hips low.
The hand they want to receive the basketball with should be extended out away from the defender.
The other arm, should act as a barrier between the post player and defender. This bar also helps with balance and movement.
