A folding exercise rowing or sculling machine has left and right fold-down oar assemblies, each formed of an arm hinged to the side of the frame, and a pivot at the end of the arm on which the oar and oarlock are mounted. A cam plate at a lower end of the pivot pulls a cable that drives the sprocket wheel of a flywheel mounted to the rear or proximal of the frame. The oar assemblies fold to rearward, with the cam wheels fitting in a space between the flywheel and the frame. Multiplier pulley assemblies couple the power cable and elastic cords to a drive chain that is wound around the sprocket.
