Position back against back pad with knees slightly bent, shoulders back, and chest high. Position both cable ropes over shoulders, one in each hand. Place hands with cable ropes in front of each shoulder so that cable is taut. If available, place hand in rope slot that allows cable to be taut when hands are in position.
Flex waist so torso pulls ropes forward and downward. Return until back of shoulders return to surface. Repeat alternating twists with opposite sides.
