With the device belted around the waist and the user in either a standing or lying down position, the device is ready to be used. The leg restrainer #25 is, depending on the height of the individual, just above the knees. The stomach pad #3 is just below the waist and the chest pad #2 extends from the solar plexus up. The handles are a little below shoulder height and about shoulder width. When the device is being used resistence comes from the pressure between moving the leg restrainer and the chest pad and handles #6 and #7. When the opposite ends of the device are moved a large force is pushed inward at the joint wherein the stomach pad was placed. To keep the device locked so that it will not extend backwards past the vertical, the ends of tubes A and B meet in front of stomach pad #3 and behind the joint.
