It comprises a box, two sets of support frames symmetrically mounted within the box, two sets of drive motors mounted on the two sets of support frames and installed facing each other, a pull rope reel connected to the two sets of drive motors, a fitness pull rope wound on the pull rope reel and extending outside the box, and a control system electrically controllably connected to the drive motors. The control system comprises a main controller, a power module, a communication module, a drive circuit, and a sampling module. The power module is electrically connected to the main controller and the communication module, the communication module is electrically connected to the main controller, the sampling module is electrically connected to the drive motors and the main controller, and the drive circuit is electrically connected to the power module, the main controller, and the drive motors. The present invention adopts two sets of symmetrical drive motors and, through their cooperation, drives the pull rope reel to transmit power to the fitness pull rope, thereby canceling out the shake and vibration during the pull rope fitness process while simultaneously reducing the load on a single motor and improving stability.
