Abstract: There is provided a muscular training apparatus that can be utilized without any limitation of a place, in which wires accumulating an elastic energy are repeatedly withdrawn and released, in order to train muscles of the human body. The muscular training apparatus includes a lengthy base (100), a fixed frame (300) fixed on the central portion of the base (100), a pair of wire reels (110, 210) rotatively coupled to one side of the fixed frame (300), wires (150, 250) each one end of which is fixed to each wire reel (110, 210) and each other end of which is wound around each wire reel (110, 210), spiral springs (120, 220) were as each one of which is fixed to each wire reel (110, 210) and were as the other end of which is fixed to the fixed frame (300), and grips (160, 260) connected to the other end of each wire (150, 250).
