Abstract
An exercise device for simulating walking and stairclimbing and providing low impact aerobics for exercising the lower body. The exercise device includes a frame mounted on a base. The frame includes an upright standard mounted on a front of the base and angled rearwardly. A handle bar with handle bar grips is attached to a top of the standard. An upper end of a pair of hydraulic cylinders is attached to the standard. A lower end of the hydraulic cylinders is attached to a first and second independent step. A front pivot portion of the steps is mounted on a pivot shaft which is mounted on the standard. A pair of torsion springs is disposed around opposite ends of the pivot shaft. The torsion springs bias the steps upwardly at an angle above the horizontal. When a user of the exercise device steps on a rear step portion of the steps and downward pressure is applied on the first step, the cylinder telescopes downwardly and the torsion spring is flexed around the pivot staff. When downward pressure is applied on the second step and the pressure relieved from the first step, the second step moves downwardly as the first step returns to its upward position. By first applying pressure on one foot and lifting the other foot, a natural floating type simulation of climbing steps occurs when using the subject exercise device.
