A multiple rigid bar mechanism serving as an exercise machine which may be characterized as providing a motion path along a closed curve. In the simplest embodiment, the mechanism comprises a motion bar rotatably connected to a flywheel and a trunnion element. The flywheel is rotatably secured to the machine frame about a flywheel base joint, and is eccentrically connected to the motion bar at a flywheel motion bar first joint. Upon input force from the machine operator at a motion bar force input region, the motion bar will be caused to pivot about a motion bar trunnion region thus effecting the motion bar first joint to translate at an eccentric radius about the flywheel or crank rotational axis. The mechanism may be used to exercise the operators upper and/or lower body, and may be described as having a reciprocating type of resistive motion with inertial characteristics of a flywheel.
