ABSTRACT:
The present invention describes a specialized exercise apparatus and method for use that targets the muscles in and around the abdominal, oblique muscles and mid section of the body. The machine is comprised of a flat platform upon which an individual stands while grasping a pair of handlebars that are positioned at waist height. The handle bars are attached to the top of a vertical riser that extends downwardly and is attached to a pair of horizontal rotating pivot arms. The pivot arms are attached to the center of a rotating power pulley horizontally suspended by bearings below the forward area of said platform. The power pulley is connected by a belt to a resistance mechanism, such as a flywheel or turbine fan, again suspended by bearings, below the rear portion of said platform. In the flywheel adaptation of this invention, additional resistance is provided by an adjustable magnet that is controlled by a lever mounted to the side of the vertical riser. An individual stands upon the apparatus, and while keeping the lower body relatively stationary, rotates the handle bars, and thus the pivot arms, from side to side up to 220 degrees of rotation and provides an adjustable measure of resistance which produces an increased use of the muscles in and around an individual's torso and midsection area.
