2A Cable Pull Through
Sets: 3 Reps: 12-15, 8-12, 6
Attach a rope handle to the low pulley of a cable station and straddle it, facing away from the station. Take a few steps forward to put tension on the cable. With your lower back in its natural arch, bend your hips backward, allowing the cable to pull your hands through your legs. Stop when you feel your lower back is about to round.
