A ball chair may comprise a chair frame, a ball body and an adjusting unit. The chair frame has a connecting base and a legs base, and a supporting column formed therebetween is configured to achieve a telescopic action thereby adjusting a height of the ball chair. The connecting base is formed in a concave shape to form a housing space therein, and an annular frame is formed at an upper end of the connecting base. The ball body is configured to be coupled on the connecting base of the chair frame, and the annular frame is configured to couple with an outer periphery of the ball body thereby limiting a position thereof. As a result, the ball chair is suitable for different statures of users and enables the users to sit thereon for training or rehabilitation.

An abdominal exercise device includes a frame comprising top, middle, and bottom frame sections. The middle frame section has a curved shape for creating a teeter-totter movement during exercise. The device includes a headrest connected to the bottom frame section, a plurality of connectors for connecting elastic bands to the frame, and an elastic band connected to at least two connectors. The two ends of the elastic band are connected to two straps. The device creates the teeter-totter movement to exercise the abdominal muscles in response to a person lying down in supine position with the back of the head on the headrest and the feet in the two straps, the person applying a downward pressure with the feet to the straps to move the headrest from a resting position, and the person removing the downward pressure to allow the headrest to go back to the resting position.

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.

Embodiments of the invention are directed to devices and methods for providing extension and flexion assistance. A device manipulates a foot of a user, thereby providing extension or flexion assistance to an ankle of the user, and includes a footplate positioned at a pre-determined distance from the user and adapted to pivot about an axis defined by the ankle as the foot extends or flexes about the ankle; and a force application system comprising a force applicator connected to the footplate, and a force application mechanism, wherein the force application mechanism is configured to apply a force to the force applicator, thereby providing the extension or flexion assistance to the foot about the ankle.

Improvements in an exercise cycle is disclosed. The cycle is adaptable to an office chair with a hook feature that allows for easy engaging and disengaging of an office chair floor leg, support or caster. The extending hook allows for users of different heights to make use of the chair hook without requiring a user to change hooks to accommodate different heights of a user and office chair casters. The pedals are connected through a common axis and connect to a loading mechanism. There can be a flywheel and a transmission that alters the turning rate of the flywheel and/or the loading mechanism. The size and shape of the resistance loading housing is configured to fit under a common office desk. The user's weight, is transferred to the plate through the office chair caster to improve the stability of the desk bike.

In one aspect, an active exercise chair comprising seat support, wherein the seat support is rigidly affixed to a top section of a shaft of the gas spring; a seat, wherein the seat is connected to the seat support; a seatback support, wherein the seatback support is pivotably connected to the seat support about a discrete pivot point; a seatback carriage, wherein the seatback carriage is slidably connected to the seatback support, wherein the seatback carriage is connected to a seatback, and wherein the seatback traverses a translational path defined by the geometry of the seatback carriage and the seatback support.

A workout system is provided that includes a piece of furniture having at least a backrest and a seat. A chair workout machine is provided coupled to the piece of furniture. The chair workout machine includes a support frame coupled to at least one structure of the piece of furniture. At least one rotatable arm is rotatably attached to the support frame. One or more resistance elements are coupled to the at least one rotatable arm, where the resistance elements arranged to provide resistance to movement by at least one body part of a user.

A chair arm exercise apparatus includes three distinct back positions with hand resistance members such as springs supported from a pair of supports spaced from the upper end of the back. The arm chair includes a base configured to rest on a horizontal floor surface, a seat, a pair of spaced apart trapezoidal shaped upright frame sides, a front upright end wall beneath and supporting a front end of the seat, a seat back pivotally supported from the frame sides behind the seat, and a seat cross member beneath the rear edge of the seat fastened to the frame sides. In a first position the back is at about 90 degrees to the seat. In a second position the back is about 80 degrees to the seat. In the third position the back is reclined.

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 for use. A cross-member is positioned at the end of each strut to form legs for supporting the pedal crank in an upright position. A tensioner is associated with the crank housing for selectively increasing and decreasing the force needed to turn the pedal crank. A telescoping arm may be used to interconnect the exercise device to a table or seat so that it can be folded and stored under the table or seat, and unstowed and unfolded for easy use.

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 pair of struts extends from the crank housing and one of the struts has a hinge that allows the leg to fold inward into a collapsed configuration or extend and lock 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.
