Abstract: A universal gym exhibits improved versatility employing a frame supporting a weight stack connected via cable to an exercise attachment point, which further engages a floating pulley with an extension cable. Accessory receiving ports throughout the frame allow placement of the floating pulley virtually anywhere the athlete desires, affording a vast array of exercises employing the weight stack. Free weights, elastic bands, and the weight stack, alone or in combination, can provide a diverse resistance. Decorative panels, optionally mounted with hollow-headed bolts each having an axial recess for receiving and retaining a panel-mounting rivet, can disguise the universal gym when not in use.

Abstract: An apparatus for exercising against a resistance comprises a frame comprising a plurality of vertical members mutually supporting a plurality of horizontal members, wherein the frame has at least a front face joining a side face at a corner; one or more doors comprising one or more door vertical members mutually supporting one or more door horizontal members, the door being pivotally and optionally slidably mounted to the frame in at least one point; wherein the frame and optionally the door provide at least one exercise attachment point. A hinge, useful for example in such an apparatus, comprises a frame brace rotatably joined to a door brace by a hinge axle, wherein the frame brace is adapted to slidably engage a track affixed to the frame of the apparatus.
