Select a bar attachment that will allow a neutral grip (palms facing each other). Place feet out in front on the foot pads, grasp the bar, and sit back into an upright posture. Knees should be slightly bent and feet hip width apart. Your arms should be extended straight out in front of the body. Engage abdominals, and pull navel in to stabilize your core. Maintain a neutral (flat to normal) spine. Exhale and pull your hands back to the sides of your ribcage. Pause then slowly extend arms back out straight. Repeat.
