Abstract
A stair type exercise apparatus is disclosed in which two pedal members reciprocate. The pedal members can either be directly connected together by a cog drive belt which in turn operates through a transmission providing a resistive force to the pedals or the pedals can be individually connected to the transmission by a drive belt. The resistive force is supplied by an alternator which is controlled by a computer.
