  • Publication number: 20070160803
    Abstract: An exercise machine comprising a unique cam coupled to a unique, multi-faceted hinge construction located between the distal portions of a yoke and the extension arms of the exercise machine. The cam functions to prevent loss of resistance through the range of motion of the exercises permitted by the exercise machine. The multi-faceted hinge comprises a swivel portion that allows the extension arms of said exercise machine to pivot on a horizontal plane such that the user may perform a pectoral fly exercise or a lateral raise exercise. The multi-faceted hinge further comprises a hinge bracket that allows the extension arms of said exercise machine to pivot in a vertical plane such that the user may perform an overhead shoulder press exercise. The multi-faceted hinge further comprises one or more fastening members that allow the extension arms to rotate along their long axis such that the user can adopt differing hand grips for variation in the exercises mentioned herein.
