3b One-Arm Cable Lateral Raise
Sets: 4 Reps: 10
Attach a D-handle to the low pulley of a cable station and grab it with one hand, your palm facing the machine. Take a few steps away from the machine and stand perpendicular to it, so that there is tension on the cable. Raise your arm up until it's parallel to the floor, and then lower it back to the starting position. Complete all your reps, and then repeat on the opposite arm.
