  • Patent number: 3948513
    Abstract: An element of exercising apparatus intended to support the body of a user and equipment being manipulated has upstanding, mutually parallel legs interconnected by a body supporting platform. Opposed ends of the platform are independently adjustably and disconnectably connected at selected locations along the length of the legs. Equipment supporting rails extend between opposed legs and are adjustably and disconnectably connected thereto. An element of exercising apparatus intended to be manipulated by a user is comprised of a central column from which a plurality of supportive members rigidly radiate. A weight retaining column extends from each supportive member in parallel relation to the central column. A lifting arrangement is adjustably connected to the central column to enable a user to lift the apparatus. A method of exercising can be engaged in using the exercising apparatus by initially resting on the body supporting platform and manipulating weighted equipment in an exercising routine.
