In a gymnastic apparatus, the actuator (22) is fitted in fixed angular position to a first shaft (16) to oscillate from initial to final position, normally maintained in initial position by a weight unit (8) and connected to the weight unit (8) by means of a driving device (33) provided with a cam (38) splined on a second shaft (34) transversal to the first shaft (16); two gears (37) are joined in angular position to the first and second shaft (16, 34), respectively. <IMAGE> |
