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.

Abstract: A compact exercise apparatus for use in performing a plurality of exercises having a resistive load is disclosed. A frame structure is provided for supporting the load and a mechanism is employed for moving the load from a first to a second position. A linkage arrangement is disposed between the moving mechanism and the load and includes a plurality of interconnected pivotably operably lever arms. The linkage arrangement is in multiple mounting communication with the moving mechanism at one of the interconnected lever arms. This combination of structure enables the proper biomechanical and kinesiological movement of each of the exercises and permits moving the load from the first position to the second position. In a preferred embodiment, a frame structure supports a movable weight stack and an exercise bar is utilized to move the load from a first to a second position.

Abstract: This invention is directed to an exercising apparatus on which multiple exercising routines may be performed from a single station area operating in opposition to a single set of weights and wherein three cable systems are operable independent from each other with pulley systems being positioned at high level, low level and mid level of the frame of the apparatus.

Abstract: An automatic force generating and control system that automatically sets exercise forces in accordance with user programmed criteria and is capable of providing pressurized flow to both ends of the arm hydraulics and leg exerciser hydraulics. Anticavitation is provided during idling, pressurized flow and when the user is successfully overcoming the pressurized flow. In the preferred embodiment, pressure is regulated by two proportional pressure relief valves which set the pilot pressure of the control valves and switching elements which direct the pressurized flow to the hydraulics. In an alternate embodiment pressure and flow are regulated by a bi-directional pump through the current and voltage sent to the pump by the controls. In a third embodiment the pressure is regulated by a proportional pressure relief valve which is connected in parallel to the ends of either the arm cylinders and to a uni-directional pump.

Abstract: A multiple exercise unit capable of providing a user with a wide range of strength and conditioning exercises. The exercise unit provides resistance through an isokinetic device which utilizes a clutch mechanism. Lines extend out of the isokinetic device and attach to various exercise elements such that a variety of upper and lower body strength exercises may be performed.

Abstract: An exercise bar is rotatably mounted relative to a central support rod, the central rod including extension members extending coaxially and laterally of the bar for mounting within opposed vertical door frame portions. The bar includes an exterior shell rotatably mounted relative to an interior shell, wherein a modification of the invention includes a central rod portion of a first diameter less than that of spaced end portions to accommodate individuals of various sized hands for mounting onto the bar.

Abstract: An exercising apparatus is provided permitting the concurrent isometric stressing of the leg muscles while performing a plurality of arm stressing exercise, or alternatively, permitting an isometric stress to be maintained in the arm muscles in a selected direction while exercising the leg muscles. All of the exercising stresses are produced by compressing springs in tubular housings, some of which constitute the frame structure of the exercising apparatus and other tubular housings being positioned in a plurality of angular positions relative to the frame structure.

Abstract: A multifunctional gym exerciser with an adjustable table having a semicircular set plate on a front edge of the main body of the multifunctional exerciser and a plurality of set holes on the circumference of the set plate, so that, by utilizing a combination of a set bolt with the set plate, a user can optionally secure various exercise attachments, such as a pedal assembly, a leg lift assembly and a sit up support according to different exercise requirements. Furthermore, through the use of a movable supporting stand located at the bottom edge of the main body, the table position can be widely adjusted, and a seat and rest seat can also be adjusted to a desired slope in order to achieve the best exercise effect.

Abstract: A multi-functional exercising machine includes a main structure, a jogging device, a rowing device, a stationary bicycle, a pulling spring, a shelf, a stand, a chair, and a pull-up bar. The stand is attached to the main structure while standing on the jogging device. The chair or the pull-up bar is attachable to the stand.

Abstract: An adjustable weight lifting machine includes a bench board adjustably secured on a bench frame by adjustably engaging a locking bolt pivotally secured with the bench board with a corresponding pair of bolt holes formed in the bench frame adapted for a proper seating or sleeping by a trainee or user on the bench board, and a plurality of weights slidably held on two guiding rods having a pair of reinforcing ribs, each rib securing each rod to a supporting column of the machine having each weight formed with two side notches in two opposite side portions of the weight so as to be freely reciprocated on the guiding rods without being obstructed by the two reinforcing ribs secured on the rods.

Abstract: A convertible gymnastic apparatus for doing push-lift movement or chest building movement makes use of a short cross bar having thereon a protruded bar extending upwardly and a swing frame comprising a longitudinal bar, to which a movable body is attached, and two gyrating arms having a baffle disposed at inner side end thereof. As movable body is moved upwardly, the movement of the baffle of gyrating arm is obstructed by the bump of the movable body so that the gyrating arm can not be rotated. Therefore, the user can do the push-lift movement. As movable body is moved downwardly, the protruded bar of the short cross bar is locked securely into the hole of the movable body, thereby resulting in prevention of the swing frame from swinging forward and allowing the user to do the chest building movement.

Abstract: An exercising apparatus which is adapted for home use and is versatile to permit the performing of a large number of exercises with a single piece of equipment and which incorporates the exercise facilities offered by several conventional pieces of exercising equipment. The exercising apparatus comprises a seat section at one end with a back rest capable of being raised from a frame for supporting the lower back during various types of exercises including abdominal exercises. The seat back can be lowered in order to enable an individual to lay in a prone condition on the exercising apparatus in order to perform additional exercises such as abdominal exercises, arm exercises and the like. A method of exercising is also disclosed.

Abstract: A multipurpose exercise apparatus may be assembled into a plurality of configurations and positioned in a plurality of orientations to perform a variety of exercises, including cross-country-skiing-type exercises and rowing-type exercises.

Abstract: An aquatic exercising device/apparatus (10) comprising a bed (11) mounted on a frame (12) supported by hollowed columns (13), and lines (17) extending through such columns (13), their one ends attached to floats (16) and their other ends attached to members (30) for or applied to the hands (31) and feet (32) of its user (26). As the user (26) pushes members (30) away, the buoyancy for floats (16) resist their submergence into the water (60) in which apparatus (10) is disposed. Tension thereby is produced for the user's muscles thus exercising them or particular ones. Neck muscles likewise are exercised in another embodiment or assembly (65) which includes a line (67) to which a head harness (66) is fastened, the line extending back to a pulley (71) dependingly mounted on a cross-beam which in turn is mounted to a hollowed standard (68), such line extending through standard (68) to be fastened to a float (16).
