ABSTRACT:
A dual operational exercise resistance device that is usable in the home or fitness center by attachment to a supporting structure. The supporting structure can be a freestanding platform base, a wall, or a door. The device can be utilized to replace the weight stack in a universal gym or any exercise machine. The device can be utilized to provide resistance from more than one point of attachment for standard exercise grips. In addition the resistance provided by the device is easily adjustable, providing the appropriate resistance for the particular muscle group being exercised. The device comprises a base that is configured for attachment to a support or exercise machine, a lever arm member having a peripheral edge being pivotally attached to the base having a pulley on end, two pulleys on opposite ends of the base being pivotally mounted on a horizontal axis within vertically orientated mounted brackets and a pulley being pivotally attached to an intermediate point on the base. One end of the lever arm member is attached to a pivotally mounted pulley to which a portion is engaged by a cable and extends therefrom in two directions for attachment to a grip at two alternate locations. To the other end of the bar attached a resistance mechanism that attaches pivotally to an intermediate point on the base. This structure reduces the resistance force produced by the resistance mechanism as the exerciser approaches full contraction of the muscle group being exercised to insure a completely full contraction is made. The device also compensates for the use of a non-linear resistance mechanism.
