An exerciser includes a pair of foot support movably supported on a base, a pair of bars pivotally secured to the base and each having an upper handle, and a pair of links and tracks movably coupled between the base and the bars. The bars each includes a slidable slide coupled to the foot supports. A motor is coupled to the slides for moving the slides along the bars to adjust the foot supports relative to the bars and to adjust the moving stride of the exerciser. A switch is coupled to the motor for actuating the motor while the bars are swung by the users.
