Patent ID: 7223216

Claim:
An exerciser comprising: a frame assembly including a lower frame portion constructed and arranged to be stably supported in an operative position on a horizontal surface and rigid upright frame structure defining laterally spaced left and right free end portions; a user support assembly operatively connected with said lower frame portion constructed and arranged to support a user thereon; and left and right moving assemblies disposed in normal inoperative positions with respect to said user support assembly constructed and arranged to be manually engaged and individually manually moved away from the normal inoperative position thereof into a desired extended position by a user supported on said user support assembly, said left and right moving assemblies comprising: left and right upper pulley members rotatably mounted on the left and right upper free end portions of said rigid upright frame structure respectively; left and right lower pulley members rotatably mounted on said frame assembly at fixed positions below said upper pulley members respectively; left and right flexible elongated structures trained around said left and right upper and lower pulley members respectively; left and right user hand grip units connected with left and right end portions of said left and right flexible elongated structures extending in positions to enable a user supported on said user support assembly to move said left and right user hand grip units away from inoperative positions thereof into desired extended positions; said left and right flexible elongated structures including left and right series of bungee cords having fixed ends and movable ends provided with (1) stop structure thereon for engaging cooperating stop structure associated with left and right pulley members respectively so as to determine inoperative positions thereof and enable resilient movements therefrom to desired extended positions and to resiliently return said left and right user hand grip units to the inoperative positions thereof when no longer moved by the user and (2) connector structure outwardly of said stop structure; left and right connecting structure on said frame assembly constructed and arranged to enable the fixed end of said left and right series of bungee cords to be fixed in selected fixed positions on said frame assembly so as to extend upwardly from the fixed positions and around the upper left and right pulley members, respectively; said left and right hand grip units having cooperating connector structure selectively connectable with the connector structure of said bungee cords so as to enable the user to connect the left and right hand grip units to any number of bungee cords in the left and right series of bungee cords and thereby select different resilient bias of said left and right series of bungee cords when in the inoperative and extended positions thereof.
