Inventor: CALVIN COFFEY Title: EXERCISE ROWING MACHINE Abstract of the Disclosure An exercise rowing machine uses a flywheel as a resistance member and has cam sector arms which are pivoted to rotate with the machine's oars. A bicycle-type chain is pulled to drive a sprocket drive on the flywheel when the oars are stroked. The arcuate shape of the cam sector arms provides a constant resistance force to the stroke of the oars over the oar sweep. The position of the foot stretcher plate is adjustable. A shroud for the flywheel has an adjustable throttle or shutter to control air flow and thus adjust the amount of resistance.
