ABSTRACT:
A resistance assembly useful to provide resistance to exercise movements performed by a user on an exercise machine includes a pair of spool-like ends disposed within a resilient loop which passes around a portion of each spool end. Each spool end is configured as a hollow open-ended cylinder with planar, annular flanges extending from both ends of the cylinder. A shield extends from a segment of one of the annular flanges of each spool end. Each spool end is composed of first and second interfitting spool parts, each comprising a hollow open-ended cylinder with one of two flanges extending therefrom. The resistance of the assembly can be varied by exchanging the resilient loop for any of a plurality of loops having different resistive properties.
