A muscle tone up device consisting from a solid frame, weight and from movable actuator, which is connected to a weight with kinematics coupling transmitting through a pull rope the dynamic action of the exercising sportsperson to a changing of the weight stage. The kinematics system contains at least on one side, a two-armed lever (8) fixed during the exercise in a chosen inclination angle, where the main arm (84) is provided with movably set guiding element (87) with a guiding pulley (83) interconnected through a guiding chain (86) with an actuator (4). On the other side, a movable element (2) slidly fits in the guiding (12) on the frame (1) containing a couple of movable pulleys (21), between which the main loop (32) of the pull rope (31) is formed, which is driven through the guiding pulley (83) of the guiding element (87). |
