ABSTRACT:
A portable exercise device for the full and efficient exercise of any group of muscles provides a predetermined and calibrated resistive force established by virtue of friction forces. The exercise device includes, a housing having an integrally formed handle or a receptacle for attaching an accessory connector at one end and an aperture at the end opposite therefrom, a sheave assembly rotatably mounted in the housing having an exercise cord windably retained therearound a moveable handle fixed to the end of the exercise cord which extends through the aperture in the housing, a braking assembly operatively associated with the sheave to frictionally and uni-directionally retard the rotation of the sheave assembly when the exercise cord is forceably unwound from about the sheave assembly, an adjustment dial for adjusting the friction forces acting against the rotation of the sheave assembly, and a spring operatively associated with the sheave assembly rotates the same during operation of the portable exercise device to normally rewind the exercise cord thereabout.
