Abstract
A step type exercise apparatus is disclosed in which two pedal members are connected for reciprocating movement by a chain which, in turn, operates through a transmission providing a resistive force to the pedals. The resistive force is supplied by an alternator which is controlled by a computer. Means are provided to lubricate the chain thereby prolonging the life of the chain.
