Stand below high pulley. Grasp cable rope attachment and place wrists against head. Squat down slightly with hips flexed, allowing resistance on cable pulley to lift torso upward so spine is hyperextended.
With knees and hips stationary, flex waist so elbows travel toward middle of thighs. Return and repeat.
Note movement occurs in waist, not hips. Hyperextension of spine at top of motion is achieved by anterior rotation of pelvis with flexed hips. See Spot Reduction Myth. Two soft stirrups or multi-exercise bar can be substituted for rope. If two soft stirrups are used, grasp stirrups at side of head. Also see similar exercises:
