ABSTRACT:
An exerciser including a base having an extension portion upward extending from a top side of the base. A handle portion is disposed at top end of the extension portion. Two pedals are side by side disposed on rear side of the base and spaced by a predetermined distance. Each pedal is connected to the extension portion via a hydraulic cylinder. Each pedal is disposed with a first rotary shaft and a second rotary shaft. A rolling belt is drivingly wound around the first and second rollers. The first rotary shaft is disposed with a sprocket and a fly wheel. A chain is wound around the sprocket. Two ends of the chain are respectively secured to the base and the extension portion. When a user steps down the pedal, the sprocket is moved along the chain and the first and second rotary shafts as well as the rolling belt are driven to move toward the rear side of the user's foot, whereby the user is subject to a forward rushing force which makes the user have a feeling like running mountaineering or stairs climbing.
