ABSTRACT:
A rowing machine comprising a base, a rowing arm pivotally mounted at one end to the base, a seat assembly pivotally mounted on the base rearwardly of the rowing arm, a foot pedal assembly pivotally mounted on the base forwardly of the rowing arm, a first connecting arm pivotally connected at one end to the foot pedal assembly at a point spaced above the base and at the other end to the rowing arm at a point spaced above the base, and a second connecting arm pivotally connected at one end to the rowing arm at a point spaced above the base and pivotally connected at the other end to the seat assembly at a point spaced above the base. In operation, as the operator pulls back on the rowing arm, the pedals move back and the seat moves back and up. The upward movement of the seat affords a certain amount of resistance to the operator as he lifts his own weight. Additionally, the operator may utilize his leg power to resist the arm movement of the rowing arm, thereby permitting him to control the amount of resistance to the rowing arm in proportion to the force exerted against the foot pedals.
