Abstract: A skier's exercise device includes an inclined platform supporting a baseplate having four retaining walls within which a turntable is rotatably mounted. The turntable is formed with a pair of parallel spaced troughs adapted to rotatably receive a pair of support members. Each support member slidably receives a foot plate equipped with foot straps releasably securing the user's feet to the plates. Each of four retaining walls is formed with a slot adapted to receive the friction pad to engage the edge of the turntable to impede the rotation thereof.
