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.

A chair facilitates both rocking and bouncing. The chair includes a base adapted to support a seating portion, the seating portion having a surface adapted to be sat on by a user. The seating portion has a bouncing mechanism, such as an exercise ball. A rocking mechanism is provided to cause the base to rock. The rocking mechanism facilitates the rocking back and forth of the user when the user is seated on the seating portion, and the bouncing mechanism facilitates the bouncing of the user when the user is seated on the seating portion. The bouncing is in a bouncing direction that is different than the direction of rocking. The chair is particularly useful for calming a baby and/or for facilitating stimming.

A method for operating a seat system, where the seat system includes a vehicle seat having a plurality of controllable moveable elements integrated into a seat cushion that forms a seat surface and/or into a seat back, includes prompting, during an activated muscle training program, a user on the vehicle seat to exert a pressure with a specific body region of the user on a predetermined region of the vehicle seat in which at least one of the plurality of controllable moveable element is arranged and determining a local and a temporal deviation between a pressure exerted by the user as an input signal and a specification as an output signal.

An exercise apparatus includes at least one resilient member; a first weight connected to a first end portion of the at least one resilient member; a second weight connected to a second end portion of the at least one resilient member, and a holding member connected to a center portion of the at least one resilient member, the center portion being between the first and second end portions. Another exercise apparatus includes a holding member; a first resilient member having first and second end portions, the first end portion being connected to the holding member; a first weight connected to the first resilient member; a second resilient member having first and second end portions, the first end portion being connected to the holding member opposite the first end portion of the first resilient member; a second weight connected to the second resilient member.

A multipurpose workout chair is an exercising equipment that not only can be used for workout training, but also can be used as a chair. The multipurpose workout chair includes adjustment devices and other components acting with each other which allows the multipurpose purpose chair to be changed into various configurations according to different training methods and each of the training methods may be executed by one or more different muscles.

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.
