Start: Position the ball under your hips with your feet on the wall, body lengthened into a straight line. Stretch both arms out over your head. Turn one foot outwards to create a fixed point on the wall.
Movement: Pulling from the outward turned foot, drive the opposite side of your pelvis into the ball and use it to roll the ball in the direction of the foot. Your body turns and your feet pivot to face the same direction.
