ABSTRACT:
An exercise machine which entails simultaneous peddling and rowing actions to afford a total body workout. The machine includes a stationary bicycle frame having front and rear sections and a beam bridging these sections. A bicycle saddle is supported on an upright post anchored at an intermediate position on the beam, at which position a sprocket wheel is mounted whose axle is coupled to foot pedals engageable by the feet of the seated individual. A front wheel is supported for rotation above ground on the front section, this wheel being linked by an endless chain to the sprocket wheel. The front wheel is engaged by a spring-biased pressure roller imposing an adjustable load thereon to resist the peddling action. Pivotally supported on the front section on either side of the front wheel is a pair of poles terminating in handle bars to be grasped by the seated individual, the poles being joined by a connector so that they swing together. Extending between the post and the pole connector is a hydraulic bar composed of telescoping inner and outer tubes, the bar offering uniform resistance in both directions as the individual rows the joined poles back and forth while concurrently peddling.
