Various improvements are provided to breathing training, monitoring and/or assistance devices. A portable device is provided which optionally includes a gas canister, a feedback system for implementing pressure control, and a visual output for indicating adherence to a breathing exercise to the user. The pressure control may provide regulation of different pressures for inhalation and exhalation.

The present invention discloses a power adjustment device. The power adjustment device includes a steel cylinder and a piston arranged inside the steel cylinder in a sliding mode, wherein the piston is fixedly provided with a guide rod, the guide rod being connected to a dustproof cover in a sliding mode, and a steel cable being fixed to an upper end of the guide rod; the piston is provided with a one-way air guide structure, the one-way air guide structure including an air guiding channel, the air guiding channel including a circular upper channel and a circular lower channel, and an adjustment ball being arranged inside the upper channel; and purposes of eliminating vibration, lowering noise, eliminating potential safety hazards, being more convenient in assembly and lowering cost are achieved.

An exercise machine support system for providing increased versatility including inclination or declination of an exercise surface, a reduction in the overall length and width of the exercise machine, and an enhanced user interface which reduces the risk of injury. The exercise machine support system generally includes a cantilevered exercise machine which is adapted to have a variable angle of incline or decline with respect to a horizontal ground surface. The exercise machine will generally include a base and a support which extends between the base and the exercise machine. The upper end of the support is connected to the exercise machine by a first pivot such that the exercise machine pivots about the support. An adjustment device may be utilized to pivot the exercise machine and thus adjust its angle of incline. Various types of adjustment devices are disclosed, including an actuator, ratchet-and-pawl, gears, and cam.

A treadmill contains a body, a support assembly, a resistance unit, and a stop strap. The body includes a holder and a circular running belt. The support assembly includes multiple posts and two columns, wherein each column having a slidable space, and the slidable space having two first chutes. A resistance unit includes two sliding devices, two limitation structures, and a force exerting element. The respective sliding device has a slider and multiple first rollers. The respective limitation structure includes two cylinder units, a resilient unit, a first fixing unit, and a second fixing unit. The force exerting element has two connection rods connected on two ends thereof, and the respective connection rod of the force exerting element is coupled with the coupling portion of the slider of the respective sliding device.

An exercise machine inclination device for providing variable exercise intensity on an exercise machine by inclining the exercise machine. The exercise machine inclination device generally includes a base adapted for being positioned upon a floor, a support structure adapted for supporting the exercise machine, a hinge pivotally connecting the base and the support structure and an actuator connected between the base and the support structure, wherein the actuator adjusts an angle of the support structure.

An exercise device for deep squat and body stretch has a device body, a damping assembly, and a pedal set. The device body has a base. The damping assembly is disposed on the base, and has a tube, a pneumatic cylinder which has multiple positioning through holes, and a seat. The pneumatic cylinder is mounted in the tube. An adjusting component is able to extend through the tube and is mounted with one of the positioning through holes. The seat is connected to the pneumatic cylinder for height adjustment. The pedal set is assembled on the device body, and has two pedals rotatably mounted on the device body.

Provided are apparatuses for augmenting human speed, human-driven compliant mechanisms, artificial limbs to augment human movement, and the like. The apparatuses can include variable stiffness mechanisms including springs that can be configured to selectively store and subsequently release energy generated by human movement. The apparatuses can selectively release the captured energy supplied by the human to provide force and power output beyond the physical capability of the human.

An exercise machine includes a cyclical actuator and a mechanical energy storage device. Connective structure operatively connects the cyclical actuator to the mechanical energy storage device. Motion of the cyclical actuator urges physical motion of and energy storage in the mechanical energy storage device. The exercise machine further includes an electric machine. A communication pathway enables exchange of data between multiple associated exercise machines such that multiple associated operators on multiple associated exercise machines have a common experience.
