ABSTRACT OF THE DISCLOSURE A frame member has a seat mounted thereon, the seat being movable therealong. The frame member also carries feet rests. A shaft is mounted across the frame member at one end thereof, and a flywheel is mounted on the shaft. Means for rotatably driving the flywheel are also mounted on the shaft, the means for rotatably driving com- prising a planetary gear system having a rotatable carrier, pinion gears mounted in the carrier, a stationary ring gear and a central gear. The central gear is mounted on the shaft for rotation therewith. A spool is mounted on the carrier for rotation therewith. A cable is wound around the spool for providing rotary motion to the spool when the cable is pulled by an exerciser during the rowing stroke. Thus, the rotary motion of the spool is transferred to the flywheel through the planetary gear system and the shaft in a speed increasing mode.
