ABSTRACT:
The invention relates to an apparatus for physical training, particularly of pre-ski type characterized by a base which rests on the ground and engages with an upper platform in such manner as to enables the latter to move angularly about a vertical axis as the result of a rocking movement about a horizontal axis imposed by the sportsman's feet bearing on the upper platform. The apparatus is also characterized by a stout belt to be worn by the sportsman and used to anchor an elastic cable fixed to the upper platform, in order to compel the feet to undergo a reactive force.
