A portable exercise device is provided which is inexpensive and easy to maintain while being capable of providing exercise to a wide variety of human muscles. The device has three padded parallel bars disposed in fixed relationship by a pair of arms. Although the two arms can be disposed in a single line, generally they are disposed to form a V-shape. A torsion device is provided to resist the swiveling of one arm with respect to the other.
