An exercise device with a crank housing supporting a pedal crank having a pair of opposing pedals that are pivotally mounted to the pedal crank. A first strut extends from the crank housing and is jointed to a second strut by a coupling that selectively allows the struts to rotate relative to each other so that the device may be folded into a planar configuration or extended and locked into place for use of the pedal crank. A cross-member is positioned at the end of each strut to form legs for supporting the pedal crank in an upright position. A strap may be coupled to one of the pair of legs for additionally securing the exercise device to an airline seat. A tensioner is associated with the crank housing for selectively increasing and decreasing the force needed to turn the pedal crank.

A folding exercise chair for resistance training has a collapsible chair frame, a pair of resistance mechanisms, and a padded cross-brace. The collapsible chair frame has a seat and a height-adjustable backing. The height adjustable backing is an assembly that enables a user to modify the height of the collapsible chair frame's backrest. The padded cross-brace is connected offset from the seat and across the collapsible chair frame to support the user's back and add comfort while the user is exercising. Each of the pair of resistance mechanisms is a device used to facilitate resistance training exercises. To that end, each of the pair of resistance mechanisms is positioned on either side of the collapsible chair frame.

A resistance band system including a frame-assembly, a plurality of linear-straps, and a plurality of removable-D-rings. The frame-assembly, the plurality of linear-straps and plurality of removable-D-rings of the resistance band system are structured and arranged in combination to allow a user to affix a linear-resistance-band to the resistance band system to provide an overall exercise system which provides the user with a plurality of locations to affix the linear-resistance-band to the resistance band system to allow a highly flexible and diverse exercise system to the user. The frame-assembly includes an upper-frame, a lower-frame, and a u-member. The upper-frame includes two primary-members, two inbars, two forward-bars, and a crown-bar. The lower-frame includes two first-members, two downbars, and down-cross-member. The u-member comp includes rises a body, two legs, and two t-couplers, with u-member rotatably coupled to the lower-frame via the two t-couplers.

A muscle toning device, attached to a chair, underneath the sitting surface of the chair, comprising: an exercise resistance device storing an elastically extendable, elongate resistance element; a user handgrip means, the elongate resistance element being attached at its second distal end to the user handgrip means; at least one guide comprising a first bearing and guidance channel, for locating and guiding the elongate resistance element; characterised in that the muscle toning device further comprises at least one second bearing, about which the elongate resistance element turns, wherein the second bearing is laterally translatable, the laterally translatable bearing being anchored to the exercise resistance device by an elastically expandable attachment means, such that when a pulling force is applied to the elongate resistance element, the laterally translatable bearing is caused to move in the direction of said pulling force.

An exercise system includes a base module having a seat with a seat depth, and a vertically adjustable back configured to fixedly engage with the base module at a first seat depth and a second seat depth different from the first seat depth.

A resistance training system includes a tackle providing mechanical advantage, and a user performs strength training exercises by pulling or pushing on the running block while resisting motion of the running block by pulling or pushing on the free end of the runner. The running block, fixed block and free end of the system may be secured at various locations of the body.

A treadmill arrangement, having a treadmill stand and an endless belt which runs over rollers mounted in the treadmill stand and is driven by a drive, with one surface of the endless belt serving as a walking or running surface. A motion state detection device is allocated to the treadmill to detect a motion state or a positional change of the legs and/or feet of the user relative to the treadmill stand and to obtain a control signal for the drive.

An office chair that is ergonomically configured to allow for the coordination of stretches to the pectoralis minor muscle, trapezius muscle, and scalene muscles to open up the thoracic outlet, release muscle tension, and reinforce proper structure is provided. The stretches may be performed by an average human user while sitting in the office chair throughout the workday. The ergonomically configured chair assembly may have a brace supported by the seatback and extending downwardly therefrom over a left and right shoulder of the seated average human in a cantilevered fashion and an arm restraining device positioned rearward with respect to the rear face of the upstanding seat back.

A compact high resistance fitness device for superior independent exercising or individual rehabilitation is disclosed including a platform base plate having at least one pivotally mounted resistance module attached to the platform base plate, where the at least one resistance module has an independent user-selectable resistance setting with incremental resistance force ranges of from about 5 pounds up to 500 pounds. The resistance module includes a pull cord coil storage spool configured to wrap and unwrap a pull cord of a small diameter, high-strength pull cord emanating from the resistance module. The high strength pull cord terminates at its outer end by a handle, such as a hand/foot receptacle, with a length sufficient to allow pull strokes of up to fifty feet or more, with as much weight resistance as a user could want in a compact and portable unit, capable of being taken anywhere for use. Of special interest is that the fitness device may include sensors and other means for collecting data and relaying that data to a smartphone, a computer, the cloud or any other device for display and processing.

A multifunctional chair includes a support body, a telescopic structure, a seat body and a pedal assembly. The pedal assembly includes a fixing rod, a movable rod, an operating element and an elastic resistance element. The telescopic structure is connected with the support body, and the telescopic structure can be operated to move telescopically relative to the support body. One end of the fixing rod is fixed to the support body. The movable rod is movably connected with the fixing rod. The operating element is located at the end of the movable rod. Two ends of the elastic resistance element are respectively connected to the support body and the fixing rod. When the movable rod and the fixing rod are rotated toward the ground by pressing the operating element, the elastic resistance element can provide elastic resistance accordingly, so that the user can perform related muscle training exercises.
