Abstract: A pre-skiing exercise device which permits body and leg movements similar to those performed when turning (Christiania-like) to the right and to the left during a downhill run. The device comprises two support bars (2) in parallel, side-by-side relation and arranged for attachment of ski-boots, either directly or through the respective ski (4). The rear sections of the support bars (2) slidably bear on an inverted V-shaped supporting cross member (6), and at an intermediate position on an articulated bar-supporting device (7), in which each of the bars (2) can rock independently of the other about an associated horizontal axis of inclination (X) transversal thereto, and both bars (2) can simultaneously perform concordant equal angular movements around associated upstanding axes of rotation (Y), which are vertical or preferably inclined rearwardly toward the inverted V rear supporting cross member (6).
