Abstract: A downhill skiing/snowboarding/water skiing simulator and exerciser is disclosed, having an adjustable declined platform on which two simulated skis move, supported on rear wheeled trucks, sideways against tension type resistance riding back and forth its curved back track. Simultaneously with the rear movement, the ski tips or simulated snowboard pivot around the reduced lateral travel of the stacked swiveling, lateral moving front ski tip assembly, while the skis move between wedge and parallel positions freely. Independent height adjustments on either side of the back track allow changes from traversing directional simulations prior to the start of an actual stop movement. Outward angled standing bars provide pulling forces for the feel of the centrifugal force of a snow ski turn or water ski/snowboard turn. The forward end of each ski is capable of lateral and longitudinal movement.
