Abstract
Abstract An exercise device is composed of a base, two cranks, two handles, two connection rods, and two slide wheels. The cranks are fastened pivotally and coaxially with the base. Each of the two handles is composed of a first rod member and a second rod member capable of sliding along the direction of the longitudinal axis of the first rod member. The connection rods are fastened pivotally with the cranks and the second rod members. The slide wheels are mounted on the base such that the slide wheels are in contact with the undersides of the connection rods for increasing the contact areas of the slide wheels and the connection rods so as to minimize the wear of the slide wheels.
