A device for moving the back and core muscles while sitting includes a rocking assembly that sits atop a base assembly, and optionally a height adjustment mechanism between the rocking assembly and the base assembly. The rocking assembly includes a rocking mechanism that sits between a base plate or platform and a seat. The rocking mechanism can be, for example, a hollow or solid hemispheric- or dome-shaped rocking mechanism, an eccentric bicylinder rocking mechanism, and/or a rocking mechanism based on an arrangement of halfpipe members. The rocking mechanisms of the exercise chair allow to the seat to rock, wobble, and/or swivel with a side-to-side rocking motion, a front-to-back rocking motion, or both a side-to-side rocking motion and a front-to-back rocking motion, and are attached to base plate and seat via a fastener that includes a solid strut that passes through the rocking mechanism and includes a plurality of Belleville washers.

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 lower back exercise apparatus exercises or imparts laterally and upwardly directed movements into a user's lower back when seated thereupon. The lower back exercise apparatus includes a lower base assembly, an upper seat assembly, and a motor assembly. The lower base assembly includes an upper, laterally concave base surface. The upper seat assembly includes a lower, laterally convex seat surface and an upper seat surface. The upper seat assembly is laterally ridable upon and movable relative to the lower base assembly. The motor assembly is drives a laterally directed, cylindrical arc length trajectory of the upper seat assembly relative to the lower base assembly. The concave and convex surfacing have a common radius of curvature with a common fulcrum point spatially located adjacent an upper portion of a user's lumbar spinal region. Lateral flexion is thus imparted into a user's lower back when a user is seated thereupon.

A multifunctional exercise fitness assisting device includes a main structure placed on a supporting surface, the main structure having first and second end faces; at least one side of the main structure is formed with a receiving space for receiving various exercise fitness equipment, wherein at least one supporting frame is provided in one receiving space. The two inner edges are respectively disposed at the pad on the top surface of the main structure, and an included angle is respectively formed between the bottom surface of the two pads and the top surface of the main structure, the angle being adjustable so as to help the user to use different exercise fitness modes. At least one pad and the main structure are provided with a limiting device which can selectively limit one corresponding pad when the included angle is adjusted to a preset angle.

An exercise apparatus having a pulley, a pair of stabilizing assemblies each configured to couple a front portion of a respective pedal element to each side of the pulley, a looped belt configured to couple the pulley to a resistance assembly, a tension stabilizer configured to maintain a tension of the looped belt on the pulley, and the resistance assembly configured to assert an adjustable resistance to the pedal elements through the looped belt. The exercise apparatus also comprises a resistance band extension for performing additional exercise using resistance bands and a transport mechanism for transporting the exercise apparatus and securing the exercise apparatus to a chair wheel or other structure during exercise.

A spring ring retainer device is described for retaining a spring ring on a spring anchor in an exercise apparatus such as a Pilates chair. The retainer device eliminates metal to metal contact between the spring ring and the anchor to minimize wear and also provide tactile feedback to a user of proper spring position on the anchor. The device is preferably an elongated unitary body having a central semi-cylindrical portion having a first radius, a first curved end portion, and a semi-cylindrical connector portion joining the first curved end portion to one end of the central semi-cylindrical portion, a second curved end portion and a second semi-cylindrical connector portion joining the second curved end portion with the central semi-cylindrical portion.

A vehicle seat assembly includes a seat base, a seat back rotatably connected to the seat base, a seat bottom mounted on the seat base, and at least one of the following mounted to one of the seat base, seat back, and seat bottom: a resistance mechanism structured to exert a biasing force on at least one exercise arm operatively connected to the resistance mechanism; a bicycle seat receptacle structured for detachably mounting a bicycle seat to the seat base; and a docking mechanism structured for detachably mounting a pedal mechanism to the seat base.

A seating apparatus cushioned for providing comfortable seating of a body for living room, office and other seating environments. The seating apparatus includes a frame for a seat, a back component, arms and legs and includes one or more supports fixed with respect to the frame and extending from the seating apparatus to provide stationary anchors for use by the body in exercising and for ingress and egress from the seating apparatus.

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, and a method of using the resistance training system to perform strength training of the arms and upper body includes pulling or pushing on the running block with one hand while resisting motion of the free end with the other hand.

An exercise apparatus having a pulley, a pair of stabilizing assemblies each configured to couple a front portion of a respective pedal element to each side of the pulley, a looped belt configured to couple the pulley to a resistance assembly, a tension stabilizer configured to maintain a tension of the looped belt on the pulley, and the resistance assembly configured to assert an adjustable resistance to the pedal elements through the looped belt. The exercise apparatus also comprises a resistance band extension for performing additional exercise using resistance bands and a transport mechanism for transporting the exercise apparatus and securing the exercise apparatus to a chair wheel or other structure during exercise.
