ABSTRACT:
A ski exercising apparatus has a carriage restrained by resilient elements to restore the carriage toward a middle position when displaced by a user simulating parallel skiing, and a single foot platform arranged on the carriage as a swing, so the force applied by a user causes the foot surface of the platform to swing to a position with the surface at substantially a right angle with the direction of the force.
