Abstract
Multifunction exercise apparatus which uses only a single weight. A frame supports various exercising stations which exercise different muscle groups. A resistance-adjusting assembly adjusts a level of resistance in conjunction with the weight needed to be overcome in manipulation of the exercising station. The resistance-adjusting assembly defines a moment arm and an axis of rotation and then varies the moment arm to vary a level of resistance. The assembly includes an elongated body portion with a plurality of moment arms defined thereon and a pair of pulleys attached thereto, a cable attached to the exercising stations, and apparatus to connect the body portion to the weight.
