Abstract: A free-standing multi-station progressive resistance exercise apparatus which is small, light weight, highly versatile and easy to use. The apparatus includes a main frame comprising a central guide column, a carriage movable upwardly and downwardly along the central guide column, a stack of weights disposed below the carriage, a selector bar extending between the weights and the carriage for interconnecting a selected number of weights with the carriage, a body engaging handlebar connected to the carriage for vertical movement of the carriage relative to the guide column; a second frame including back to back guide tracks for guiding the vertical travel of first and second sheaves and first and second cable systems operably connected to a plurality of remote body engaging members for use in performing a wide variety of arm and leg exercises, the cable systems interconnecting the body engaging members with the weights via the sheaves and the carriage.

Abstract: A bench type exercise device which can be readily adjusted into several different starting positions to permit the performance of a wide variety of body exercises in a sitting position, a prone position, and a reclined position. The device is provided at the outboard end with a body engaging subassembly which, in a lowered position, can be used for various leg exercises such as leg extensions and which, in a raised position can be used for the performance of various arm exercises such as arm curls. The device further embodies remotely located weight stack, or other resistance providing mechanism, which is uniquely interconnected with the body engaging subassembly by means of an adjustable linkage assembly to provide a constant, uniform and predeterminable resistance to pivotal movement of the body engaging elements whether the elements are disposed in a lowered or elevated position and whether the device is being used for the performance of leg exercises or arm exercises.

Abstract: A barbell-like exercise device having an elongated bar of the type adapted to carry interchangeable weights. The bar is provided with grooved end portions and spaced apart radially enlarged protuberances against which the weights are held by clamping collars. The clamping collars include threadably interconnected cylindrical members which carry radially movable locking members which are adapted to be brought into locking engagement with the grooves in the bar upon relative rotation of the cylindrical members.

Abstract: An exercise bench for use by a trainee in the performance of free weight exercises using a barbell type apparatus including an elongate bar with weights carried on either end thereof. The bench includes a first frame assemblage having a pair of spaced apart upstanding members, including cradle-like supports for supporting the elongate bar of the barbell apparatus and a second frame assemblage. The second frame assemblage includes a seat portion and back portion, a part of the seat portion being uniquely disposed forwardly of the plane of said upstanding members and a part being disposed rearwardly thereof. The back portion is also rearwardly spaced apart from the plane of the upstanding members so that, with the barbell apparatus being supported on said support cradles, the trainee can sit on said seat portion facing the elongate bar of the apparatus and lean against the back portion with his upper torso positioned between the elongate bar and the back portion.

Abstract: A resistance exercising machine having a similarly configured triangularly shaped main frame adapted to carry at least one stack of weights and a pivoted engagement mechanism which is operably coupled with the weights and is adapted to be engaged by the trainee to cause a controlled movement of the mechanism relative to the main frame against the urging of the weights.

Abstract: An exercise bench for use in performing free weight exercises which includes interconnected first and second tubular frame members which cooperate to provide a base frame for the planar benches which support the trainee. The first frame member is substantially "U" shaped having transversely spaced apart upstanding legs which are interconnected by a rigid cross-member. The second centrally disposed frame member having at least one ground engaging support leg and a longitudinally extending support element disposed in a crossing relationship with the rigid cross-member of the first frame. This longitudinally extending support element supports the fixed and an adjustable planar bench portions which portions are hingeably interconnected together.

Abstract: A progressive resistance exercising machine having a single, substantially vertical guide column adapted to guide a reciprocating member which is provided with a laterally outwardly extending lifting arm engageable by the trainee. Both the guide column and a weight selector bar to which the reciprocating member is connected extends through centrally disposed apertures formed in a plurality of weights positioned substantially directly below the selector bar. When the selector bar is selectively interconnected with one or more weights in the weight stack, a lifting force exerted on the lifting arm will cause the reciprocating member and the selector bar to move upwardly against the urging of the weights. As the reciprocating member is moved upwardly, the central guide column accomplishes the function of uniquely guiding the travel of both the reciprocating member and the selector bar as well as constraining the path of travel of the weights.

Abstract: A progressive resistance exercising machine having a single, substantially vertical guide column adapted to guide a vertically reciprocative carriage provided with a laterally outwardly extending lifting arm engageable by the trainee. The design of the highly compact machine is unique in that the guide column, as well as a weight selector bar which is connected to the carriage, extends through centrally disposed apertures formed in a plurality of weights positioned substantially directly below the carriage. When the selector bar is selectively interconnected with one or more weights in the weight stack, a lifting force exerted on the lifting arm will cause the carriage and the selector bar to move upwardly against the urging of the weights.

Abstract: An exercise device adapted to simulate the riding of a bicycle comprising a supporting frame, handlebars, a seat, a front wheel and pedal cranks engageable by the trainee to impart rotational movement to the front wheel. The degree of impedance to rotation of the front wheel can readily be adjusted by the trainee during performance of the exercise. The device also includes a unique impedance indicating feature which dynamically indicates to the trainee the degree of resistance against rotation of the front wheel which is being experienced at any given time.

Abstract: An improved exercising apparatus specifically designed to permit, in a single compact unit, barbell type, lifting exercises as well as pull type, muscle toning exercises. Incrementally selectable, vertically movable weights are raised and lowered either by the exertion of vertical straight line forces on a vertically adjustable body engaging means removably connected to a vertically movable carriage which is directly coupled with the weights, or alternatively by the exertion of pull type forces on a second body engaging means coupled with the weights through a system of pulleys which reduces the amount of force required to raise the weights by a predetermined amount.

Abstract: A portable back rest adapted to be detachably mounted onto stadium bleacher seats and the like. The back rest is formed of a single piece of flexible material and comprises a back panel, a pair of side panels hingeably connected thereto, and front and rear locking elements adapted to securely grip the bleacher seat. In its transport configuration, the side panels fold inwardly into close proximity with the back panel, thereby forming a compact readily portable unit.

Abstract: An exercising machine comprising an upright supporting structure having vertical tracks, a vertically reciprocative carriage mounted in and guided by the tracks, adjustable resistance supported in the upright structure between the tracks below the carriage and connected directly to the carriage, and body-engaging member which is adjustable to different starting positions.The novel exercising machine does not utilize ropes, cables, pulleys, etc., but rather, embodies a direct connection between the carriage and the resistance. With such an arrangement, the machine is simple to operate, occupies a minimum of floor space, and requires minimum maintenance.
