A device for an exercise apparatus includes a linear adjustment system and a sensor coupled to the linear adjustment system. The exercise apparatus includes a loading interface and a frame coupled to the loading interface for performing an exercise. The linear adjustment system fixes the loading interface of the exercise apparatus at any one of a plurality of functional positions in a functional range of the loading interface. The sensor measures the force exerted on the linear adjustment system. A correlating mechanism is used to correlate the force exerted on the linear adjustment system with the force exerted on the loading interface. The device allows exercisers to exert high or maximum loads in any one of a plurality of positions throughout their entire range of motion without first passing through a weak range of motion.

An exercise machine is disclosed. The exercise machine comprises a tension generating device. The exercise machine comprises a translatable arm mount coupled to the tension generating device. The exercise machine comprises an arm coupled to the translatable arm mount. The exercise machine comprises a cable coupled to the tension generating device via the arm.

An exercise machine comprises an arm support, including: a carriage configured to slide within a track attached to the exercise machine; and a support assembly that floats the carriage relative to the track, wherein the support assembly is disengaged by the application of force via the arm. An exercise machine comprises a rotatable column, wherein the column supports an arm, and a gear detent mechanism to support a discrete number of positions for the rotatable column. An exercise machine comprises a tiltable arm, and a mechanism to support a discrete number of positions for the tiltable arm.

Systems and methods for fitness tracking are provided. A fitness tracking computing system conveys information over a network to a visual display of a device viewable by a user. The device can be a smart phone, tablet computer, or a laptop. Instructions are conveyed to the visual display that identify an exercise to be performed by the user. during performance of the exercise by the user, an exercise status summary is provided to the visual display. Based on the user's movements during performance of the exercise, as tracked by a camera, feedback is provided to the visual display.

An exercise machine reversible resistance system for reversing the directional force of resistance against an exercise implement before, during, or after the performance of a routine of one or more exercises. The exercise machine reversible resistance system generally includes a frame, an elongated member movably positioned upon the frame, wherein the elongated member has a first run and a second run, a resistance device that applies a resistance force to the elongated member in a single direction, an exercise implement movably connected to the frame and a clutch connected to the exercise implement. The clutch is adapted to selectively engage the first run or the second run of the elongated member for selective control of the resistance direction of the exercise implement.

A device for producing assisted motion, active motion, and resisted motion of the lower extremity. The device includes an upper leg support with two pull handles and a transverse axis of rotation for elevating and lowering the user's upper leg and a foot plate with a transverse axis of rotation and rollers on linear motion track(s) allowing the lower extremity to be secured into the device while maximizing range of motion of the knee joint. The upper leg support and the foot plate are both attached to the baseboard, but are not connected to each other and can move independently of each other, allowing the device to be used in multiple positions and to fit a wide range of lower extremity sizes without the need for the device to be adjusted or custom fit to the user's lower extremity.

A fitness machine enabling several lunge and squat-style exercises comprises a frame that provides the basic structure of the machine. The frame includes a set of horizontal beams and a set of vertical beams creating a rectangular interior exercise space for a user to stand. A handle is included with each horizontal guide rail that slides forward and backward along the horizontal guide rail. The horizontal guide rail is movably connected between two of the vertical guide rails such that the horizontal guide rail freely slides up and down the vertical guide rails, ensuring that the horizontal guide rail maintains a parallel relationship with the floor throughout the entire range of motion during use. The handles and the horizontal guide rails significantly improve the user's balance during the exercise, eliminating unnecessary stress on the knees, hips, and lower back.

An exercise apparatus with an adjustable rotating element around which a force transferring material wraps either clockwise or counterclockwise to provide bidirectional rotational resistance for exercising. The force transferring material is preferably guided to remain in close proximity to the rotating element while wrapping around the rotating element. Multiple attachments provide great flexibility in performing exercise or physical therapy.

A method for treating pronator syndrome involves selecting an arm and positioning it with the forearm perpendicular to the upper arm. The hand of the arm is engaged with a grip located inside a bisected working circle, which has an outer perimeter consisting of four quadrants. The fourth quadrant is elliptical and asymmetrical to the others. The grip is designed for hand engagement and includes two d-shaped slots. A resistance band is attached to the body, with one end in the groove, creating tension when used. To exercise the arm, the body is rotated in one direction to increase tension on the band. Releasing tension is achieved by rotating the body in the opposite direction.
