This apparatus comprises a bar 1 whose ends are connected to elastically extensible elements 6 themselves fastened on a stable fixed support, for example on a wall, in order to exert on the user's arms variable forces similar to those exerted by the wishbone of a sailboard, and a means for supporting the user's body in variable positions of balance comparable to that of a sailboard, comprising a support 42 fastened in a removable manner on a shaft 43 connecting two rings 44 sliding on bars 45 which are themselves symmetrically linked by supports 46 forming a base. The two bars 45 are equipped with a compressible spring 47 which enables the support 42 to move in both directions as a result of the thrusting action of the user's feet. <IMAGE>
