Abstract: An exercise method having one or more exercise members connected by a cable system to a weight, such as a variable weight stack, and each movable by a user along an exercise path to perform an exercise routine against the resisting force of the weight, and a pre-stretch adjustment feature, whereby the position of each exercise member along its exercise path at which the resisting force of the weight commences to act on the member, and hence also the portion of the exercise path over which the resisting force acts on the member, are adustable in order to vary the exercise routine performed with each exercise member.

Abstract: This disclosure is directed to an easily disassembled sit down exercise device to enable the user to concentrate on exercising primarily the muscles of the face and neck particularly enabling the selective use of low weight poundage thus permitting physically able persons to improve their facial and neck muscle tone. This sit down device has a front bench having hand grips and rear legs having foot plates on each side; front adjustable supports housing a single front pulley; an intermediate support and guide member containing a carriage, multiroller assembly and a lower intermediate pulley to which a desired selected poundage of weights can be attached; a common base for the bench rear legs, front and intermediate supports; a cable permitting movement of the selected weight(s) during exercise, passing over the upper intermediate pulley and under the front pulley and connected at one end to a harness which is connected to a headband worn by the exerciser.

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: 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 exerciser for exercising arms includes a frame assembly and an input mechanism which has a pull rope. The pull rope has a fixed end and a movable end connected to an arm exercising mechanism. A suspended pulley set includes a pulley seat on which an upper pulley and a lower pulley are mounted. The pull rope extends around the upper portion of the lower pulley, while a guide rope extends around the lower portion of the upper pulley. The guide rope is fixed on the frame assemby at an end thereof. When the pull rope is pulled, the suspended pulley set moves downward so as to rotate an intermediate drive wheel. An endless flexible driving element is trained between the intermediate drive wheel and a driven wheel so as to rotate the driven wheel. A resistance setting unit is disposed on the frame assembly and can be adjusted so that a generator unit creates a predetermined amount of electric current, thereby activating a magnetic controller to change magnetic resistance to the rotation of the driven wheel.

Abstract: The invention herein is a machine for exercising the legs and lower extremities of the body by placing most of the forces of exertion below the hips. A two sided frame, which is L-shaped, has a chain-sprocket transmission system connected to weights. The chain is mounted on a sprocket directly above the weights and pulls them up vertically. The chain extends down to the bottom of the frame and meshes with a lower sprocket almost at floor level. The chain then extends to the front of the frame above the floor level to a location contiguous to the area where the exerciser stands and meshes with another sprocket. The chain is connected to a coupler to which a belt is connected. The exerciser places the belt over his/her hips and pulls up on the chain by extending his/her arms onto an arm rest which has grips. The exerciser stands on a platform.

Abstract: An isoinertial lift machine is described which can be used to evaluate and train patients in the static and dynamic lift modes. The machine consists of an arm which can be positioned on a vertical column. At the end of the arm, various size attachments and handles can be attached. The arm also carries a force sensor that measures the forces applied to the handles. In the static mode, the arm is positioned at a desired height and locked in place. The patient lifts on the handle, and the force sensor registers the lifting force. Since the handle does not move during the lift, the mode is called static. In the dynamic mode, the arm/handle moves in the vertical direction during the lift. A resistance mechanism is used to resist the lifting force applied by the user at the handle. The resisting force is always pulling the arm down, both in the lifting and the lowering motion. The resisting force remains constant throughout the range of motion during lifting.
