Claim:
An exercise device comprising: a stretchable cord having opposing first and second ends, said cord having an internal cavity and an external surface; a flexible tether adjacent each of said first and second ends, each of said tethers including a compartment in which said first and second ends, respectively, of said cord are retained; a retaining member within said internal cavity adjacent each of said first and second ends and being located within the compartment of an adjacent tether; a sleeve attached to said cord adjacent each of said first and second ends, at least a portion of said sleeve being within the compartment of an adjacent tether, each of said retaining members being in the compartment of an adjacent tether and being located within a length of said sleeve located within said compartment of said adjacent tether; a governor including a limit band situated within the internal cavity of said stretchable cord and including opposed, first and second end segments; said retaining members aiding in retaining the cord within the tethers and in retaining the opposed first and second end segments of the limit band in a position within the cord to stretch or move with the cord as said cord is being stretched during exercising, said limit band limiting the distance that the cord can be stretched; said retaining members each including a cup-shaped outer member and an inner member having an outer peripheral surface, each of said cup-shaped members having a peripheral wall having an inner surface and a passage through which a respective end segment of the limit band extends; each of said end segments of the limit band being secured against movement to the inner member of a respective retaining member, said inner member of each of said retaining members being retained completely within an inner compartment of a respective cup-shaped member for maintaining said inner member in proper position to move with said cord, said cup-shaped member engaging said cord to expand the cord outwardly and thereby aid in retaining the limit band secured for movement with the cord.
