Using a floor level pulley, take hold of a handle with one hand. If done standing use a balanced stance. The leg opposite the arm you will be using in the exercise forward, other leg back. Begin with your arm fully extended in front of you. You may even want to twist your hand inward so that the thumb is lower than the little finger to create the fullest possible stretch. Pull the handle back by your side as far as you can, twisting your hand outward so that the thumb ends up on the outside, feeling the back muscles contract. Release and extend your arm and twist your wrist back to the starting position.
