US Patent 9028374 Rowing exercise device

A rowing exercise device simulates rowing including lateral pivoting movement to require control of core muscles, thus providing a more complete exercise experience. The device includes a frame having a pair of spaced supports and an elongated track coupled to and extending between the supports. A handle is coupled to the frame proximate a first end of the track. A seat is slidably coupled to the track wherein the seat is movable along the track to simulate a rowing motion. The seat is laterally pivotable relative to the track to require a user positioned on the seat to utilize core muscles to maintain balance on the seat as the seat moves along the track.
