It contains primarily of a vertical and rectangular frame, having a board pivotal on the top in a see-saw like fashion by the user. It further includes roller mounted footrests, and a connecting rod is secured to the board and is secured to a crank arm and sprocket, which by a chain, drives a second sprocket attached to a flywheel, which will cause the ski-motion to continue, after a few applied motions of the user to the board of the machine.
