## Abstract

An exerciser includes a right pedal and a left pedal, both of which are alternatively operated by the user to drive the right and left links so as to move the right and left swinging arms respectively, such that the hands and feet of the user are exercised. The exerciser includes a resistance mechanism which is located at the front end of the base together with the pedals and the swinging arms, and an adjustable seat is located at the rear end of the base. Therefore, when in maintenance to the resistance mechanism, the maintainers can directly access the resistance mechanism without removing the adjustable seat.
