发明名称 Leg and hip exercising apparatus
摘要 A rotatable exercise mechanism for interacting with the body in order to perform exercises. The rotatable exercise mechanism includes a pulley mounted on the frame. A cable is secured to the pulley such that the cable can be wound in opposite directions about the pulley. As the pulley is rotated in either a clockwise or counter-clockwise direction, the cable is both paid out from and wound onto the pulley. An adjustable resistive force is supplied for interacting with the cable being wound onto or paid out from the pulley. A crank for applying a rotative force to the pulley is also supplied. The pulley is rotated by applying a rotative force to the pulley capable of overcoming the resistive force applied to the cable.
