Loop the band around a sturdy post that will not move and grasp it in one hand.

Stand in a staggered stance with one foot forward and the other foot back while facing away from the anchor point while leaning the torso forward to the same angle as the band.

Hold the band with the palm facing away and the elbow tucked against the side of your ribs.

Begin with the arm at full extension, then simply by hinging at the elbow and focusing on the bicep do all of the work as you bring the hand up the the shoulder.
