ABSTRACT:
A stepping exerciser includes a pair of bars pivotally secured to a front portion of a base and each having an upper portion for being grasped by hands of users. A wheel and two cranks are rotatably supported on the base, two links coupled between the cranks and the bars, two beams pivotally secured to the bars and each having a front rod, two levers attached to the cranks, and two poles coupled between the beams and the levers to support foot supports. Two arms are coupled between the bars and the beams. An adjusting device may adjust the lower portions of the arms relative to the beams, to adjust a coupling relation between the beams and the bars and the arms, and between the poles and the levers, in order to adjust a moving stroke of the foot supports.
