<p>The invention relates to an exercise device capable of entirely supporting a person's head, back and buttocks (seat) through the use of a carriage (located and moving on the inclined semi-circular tracks) and the feet through the use of the foot rest. The semi-circular tracks and the foot rest are mounted on vertical posts which are connected to a solid rectangular frame. The movement of the carriage is made possible by four small wheels fastened at the bottom of the carriage, which roll in corresponding partially covered grooves of the semi-circular tracks. The body weight of a person is used as a resistance for the exercises which can be varied by changing the inclination of the tracks. When a person is properly positioned in the device, the person's body moves the carriage up the tracks by the interaction between the torso and the legs. The flexed legs extend and the head and back resist the leg action by pressing against the carriage. On the way down, the legs (by flexing) control and stop the movement of the body and carriage. Thus a beneficial exercise for the legs, buttocks, pelvis, lower back, upper back and neck is generated. This exercise may improve the person's body posture. The device is further equipped with two pairs of firm handles on both front and rear posts, with another set of handles, cables and pulleys on the back end of the tracks and with similar pair of handles on the sides of the carriage. All these handles serve for the various arm exercises executed with or without the assistance of the rest of the body.</p> |
