Abstract
Abstract An improved exercising apparatus includes a supporting stand (10) that firmly stands on the floor. A pair of position-adjusting devices (30, 30') are disposed at the front end of the supporting stand (10). A roller (33) is rotationally disposed atop the position-adjusting devices (30, 30'). A pair of connecting members (50, 50') are connected to a crankshaft (41, 41') at one end. The crankshafts (41, 41') are pivotally connected to both ends of the shaft (42). The shaft (42) is connected to the supporting stand (10) by means of an extending section (421). The bottoms of the connecting members (50, 50') are moveably supported on the roller (33). The connecting members (50, 50') are provided with a pedal (51, 51') for supporting the user. By the provision of the exercising apparatus, the user may run thereon or conduct a movement which simulates mountain climbing.
