Attach a rope to the high pulley of a cable station and grab each end so your palms face each other. Step away until your arms are straight out in front of you and you feel tension in the cable. Now pull the middle of the rope toward your eyes by bending your elbows, squeezing your shoulder blades together and flaring your upper arms out to your sides. To go back to the starting position, slowly straighten your arms in front of you.
