Attach a rope to a high pulley of a cable station.
Keeping your elbows at your side, bend your arms and grab an end of the rope with each hand, palms facing each other.
Draw your shoulders down and back, keeping them in that position throughout the entire movement.
Press the rope down toward the floor while spreading your hands apart. Continue to press the weight until your arms are fully extended. Make sure your elbows stay at your sides the entire time.
Slowly return the rope to the starting position, pause, and repeat.
