ABSTRACT:
An exercise machine having one or more exercise members connected by a cable system to a weight, such as a variable weight stack, and each movable by a user along an exercise path to perform an exercise routine against the resisting force of the weight, and a pre-stretch adjustment feature, whereby the position of each exercise member along its exercise path at which the resisting force of the weight commences to act on the member, and hence also the portion of the exercise path over which the resisting force acts on the member, are adjustable in order to vary the exercise routine performed with each exercise member.
The pre-stretch adjustment may be implemented with a pulley which is selectably positioned so as to adjust the maximum amount of slack in the cable or by a free sliding pulley having a selectably positioned stop.
