Abstract: A lightweight exercise device offers variable resistance, including assisted resistance, for strengthening and conditioning various parts of the body. The device may be strapped to the user's back and is provided with rollers for contact with a wall, door, pad, or floor. The rollers, are mounted on rotatable axles on the rear face of the device and operate in conjunction with a tensioning system which uses durable elastic cords or bands. As the rollers are rotated in one direction, the cords or bands wind about the axles thereby progressively increasing the cord or band tension. This increased tension thereby increases the resistance to rotation of the axles and the rollers mounted thereon. As the rollers are rotated back, the cords or bands unwind and the roller resistance decreases. The cords or bands may be wound by rolling the rollers or, in one embodiment, by turning a tension preadjustment crank connected to an intermediate axle.
