Abstract
A rocking chair provides abdominal exercise by user actuation of pivotal armrest handles that are configured to provide a crunch type exercise motion. The arrangement of internal pivot frames is such that armrest handle actuation shifts the user's center of mass both vertically and longitudinally, which in turn initiates a natural rocking motion by gravity. The inertial dynamics of the resulting motion are inherently kinesthetically pleasurable. The resistance is provided by the user's own body weight with variation through differential leverage. Alternatively, the configuration of the armrest handles is such that a user may benefit from an isometric exercise by simply holding them stationary in a conventional armrest position.
