An exercise apparatus comprises a frame with a chamber having a piston slidable between first and second cavity ends of the chamber, and a cable assembly for pulling the piston by an applied force towards the second cavity end to cause a vacuum in the chamber to exert a resistance force on the cable assembly. A cable subassembly extends between first and second parts of the cable assembly, comprising a pulley wheel attached to the first part and a cable extending around the pulley wheel having first and second cable ends. Stoppers on the cable ends engage a bearing member to restrain movement of at least the first cable end when the second cable end is pulled relative to the pulley wheel. Releasable connector means connect the cable ends to the second part to allow a user to choose a magnitude of the resistance force opposing the applied force.

A foot support assembly for an exercise machine may be configured for sing-hand operation (e.g., cinching or releasing of the foot strap). The foot support assembly may include a footplate coupled to the frame of the exercise machine and configured to support the user's foot during exercise and a strap coupled to the footplate and configured to resist separation of the user's foot from the footplate. The strap is operatively associated with a quick release ratchet mechanism, which is configured to be unlocked simply by pressing a lever of the ratchet to allow the ratchet strip to reverse, releasing the user's foot from the strap. The foot support assembly may be provided on each side of the seat rail of a rowing machine, which may alternatively or additionally include a multi-grip handle including a plurality of grip portions configured to position the user's hand at different orientations to one another.

A parallel resistance rowing machine is an apparatus that provides adjustable, independent resistance to a user to perform rowing exercises that isolate and emphasize various laterally opposed muscle groups. The parallel resistance rowing machine uses a first resistance assembly and a second resistance assembly mounted to an axle within a chassis. The first resistance assembly and the second resistance assembly are selectably interconnected by a clutch mechanism, enabling a first handle and a second handle to be moved independently or in concert under resistance from the first resistance assembly and the second resistance assembly, respectively. An elongate frame supports a slidable seat assembly, further supporting a full-body rowing action as the user exerts themselves against the first resistance assembly and the second resistance assembly.

An aqua-resistance exercise device includes an elongate member, a strap, fasteners, and one or more fins. The elongate member includes an engagement portion, a shaft extending from the engagement portion, and a handle to be gripped by a user. The fasteners are provided to the engagement portion of the elongate member and an inner side of the strap to releasably attach the strap to the engagement portion of the elongate member. The one or more fins are adapted to be received on the strap, and the fasteners releasably secure the strap to the engagement portion of the elongate member to thereby releasably secure the fins to the elongate member.

A computing system for determining osteogenic loading from an exercise apparatus for performing an exercise is provided. The exercise apparatus includes a loading interface, a frame, a linear adjustment system interposing between and fixedly coupled to the loading interface and the frame, and a sensor coupled to the linear adjustment system. A position of the loading interface of the exercise apparatus is adjusted through a movement of the linear adjustment system at one or more intermediate positions of a plurality of functional positions of the loading interface. A force exerted by a subject on the loading interface at the position in the one or more intermediate positions is received. A measurement of the force exerted by the subject on the loading interface at the position in the one or more intermediate positions from the sensor is obtained. A corresponding osteogenic loading for the force exerted by the subject is determined.

The present invention relates to a chest expander including a head, two operating arms of which upper end portions are coupled to the head using rotating shafts, and at least one gas spring disposed between and coupled to the two operating arms by a lower end of the gas spring being rotatably coupled to one operating arm and an upper end of the gas spring being coupled to an upper portion of the other operating arm, wherein a moving hole extending in an arc shape about the lower end of the gas spring is formed in the upper portion of the operating arm, a slider is provided to movably support the upper end of the gas spring along the moving hole, and the slider includes a stopper which fixes the slider.

Embodiments herein are directed to an aquatic exercising assembly. The aquatic exercising assembly includes a container having a liquid retention portion. The liquid retention portion includes a bottom wall, a pair of opposing sidewalls, and a pair of opposing end walls, a pedal assembly and a paddle assembly. The pedal assembly is rotatably coupled to the one of the pair of opposing end walls. The paddle assembly is coupled to each one of the pair of opposing sidewalls. The paddle assembly is movable between a rearward position and a forward position in a longitudinal direction. The pedal assembly is rotatably moved by a lower body movement of a user and the paddle assembly is moved by an upper body movement of the user.

An exercise machine which is capable of having its lift, roll, or pitch adjusted with respect to a base so as to provide a plurality of positions of the exercise machine with respect to the base. The exercise machine generally includes a base and an exercise machine movably connected to the base. The exercise machine may include a track, a carriage slidably connected to the track, and a biasing member attached to the carriage to apply a resistive force to the carriage. A plurality of actuators may be connected between the base and the exercise machine. The plurality of actuators may be utilized to adjust a pitch angle or a roll angle of the exercise machine with respect to the base. The plurality of actuators may also be utilized to lift or lower the exercise machine at a constant angle of pitch and/or roll inclination.

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.
