ABSTRACT:
An exercise machine comprising a frame for supporting the vertical lifting of a stack of weights. The stack of weights are connected to a cable which passes through a pulley for multiplying the amount of force necessary to lift the stack of weights when a person using the exercise machine pulls on the end of a cable remote the stack of weights. The mass of the weights necessary for lifting in order to achieve the same force to be exerted by a person is thereby reduced.
