Ski simulation device has at least two arching rails parallel each other on a sloped plane elevated at an angle of a variable degree, joined to frame structure which includes handgrip and cross rail, arching rails providing track; a carriage rides in side-to-side movement on track; whereas carriage on which platform is mounted around axis, whereas platform on which two cradles each is mounted around its axis, whereas cradles wherein two rocking footrests are nested; resistance members providing a constraint on carriage as it rides on track; dampening member extending from front section of frame structure joined to midpoint on transverse bar of which ends joined to cradles; an assembly of rollers mounted on frontal sides of both cradles, whereby rollers as guide roll on cross rail; and rod extending from front section of frame structure to a point where mounted ball can be reached by user's both knees.
