Purpose of Exercise: To develop the rear deltoids by isolating and flexing the rear deltoid when reaching the top position of the Cable Lateral movement.
Sitting on a stool or a low bench, take hold of a handle attached to a floor level pulley in such a way that your arm is fully extended across the front of your body. Keeping your body as still as possible, pull the handle across and up until your arm is fully extended to the side at about shoulder height. At the top of the movement flex your rear deltoid to get a really full contraction. Lower the weight back to the starting position. Finish your repetitions, and then repeat with the other arm.
