The present invention relates to an exercising device (1) comprising a lever or power arm (10) which is able to be arranged by a first end (12) on a retaining element (16) at a first articulated joint (13) in a way pivotable about a pivot axis or pin (14), whereby a resistance element (18) is able to be coupled by a first end region (20) at a first coupling point (22) on the power arm (10), and by a second end region (24) at a second coupling point (26) at a second articulated joint (25) on the retaining element (16). The exercising device (1) is able to be detachably arranged on a structure (40) by means of an engaging connection, which is formed by a hook-shaped recess (50) and a rod-shaped element (46) and whereby the exercising device (1) is lockable in an engaged position by means of a fixation.

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. The respective column has a slidable space, and the slidable space has 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.

Disclosed herein are methods of exercising human arms, including a method of exercising human arms that may include: 1) providing an arm exercise assembly, comprising: a) a frame; b) a wheel coupled to the frame; c) two locks disposed on the wheel; and d) a handle coupled to the wheel; 2) coupling the two locks to the wheel; and 3) abutting the handle against one or both of the two locks.

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 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.

A multi-axis adjustable exercise machine which is pivotable about both a pitch axis and a roll axis with respect to a base for allowing an exerciser to perform a wide range of exercises on a pitched or rolled exercise machine. The multi-axis adjustable exercise machine generally includes an exercise machine which is adjustable with respect to a base. The exercise machine may be pivoted about a roll axis to adjust the roll angle of the exercise machine or may be pivoted about a pitch axis to adjust the pitch angle of the exercise machine. One or more actuators may be connected between the base and the exercise machine to effectuate the pivoting of the exercise machine about either or both axes with respect to the base.

A direct-drive bicycle training system and methods of using the same are provided. The system includes a bicycle trainer that rests on a support surface and supports a bicycle frame in an upright manner with respect to the support surface. The bicycle trainer includes a stator, a rotor that rotates with respect to the stator, a cassette affixed to the rotor, a support frame supporting the stator, rotor, and cassette, and a resistance applying mechanism that operatively couples to a portion of a drivetrain of the bicycle frame and applies varying levels of resistance to the portion of the drivetrain. The support frame moves with respect to the support surface in response to a force applied to the drivetrain of the bicycle frame during use of the bicycle training system, generating a more natural movement of the bicycle and simulating on-road use.

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.

The present invention relates to fitness equipment. The fitness equipment includes a support; and an extendable member for extending from the support. A lock is provided for locking the extendable member at non-discrete positions. Advantageously, the lock can lock the extendable member at any one of the non-discrete positions that best suits a particular exerciser.
