Abstract
A user-manipulated modular exercise machine has individually operable and simultaneously adjustable right and left-hand reel assemblies. Each reel assembly includes a reel, a pull-cord wound on the reel, and a spirally wound spring which applies to the reel a reactive torque of changing magnitude as the reel rotates in response to pulling input force applied to the pull-cord. Each reel assembly has a compensating mechanism for nullifying changes in the magnitude of the reactive torque as the reel rotates and which includes a prewound spiral spring and a belt and cam mechanism for connecting the prewound spring to the reel.
