<p>Apparatus for improving the musculature of the thighs and pelvis by simultaneously divaticating the two legs of the previously stretched-out user lying on the floor, in opposition to a force constantly urging the legs towards each other, comprising, an elongated base member adapted to be laid directly upon the floor and to constitute the lower frame structure of the apparatus, a user being postionable on a floor at right angles to the elongated member with his legs passing over the elongated member, a pair of spaced apart members rigidly mounted and disposed above and extending substantially parallel to the elongated base member, each of the members having a pressure pad mounted thereon, and spring means mounted therein for biasing the pressure pads towards each other, stop means for limiting the movement of said pressure pads towards each other while under the biasing force of the spring means so that a user can fit his or her ankles therebetween in contact with the pressure pads. Abutment means are provided on the elongated base member for limiting the lateral sliding movement of each one of the pressure pads with respect to the elongated base member, and each the spring means has an adjustment means for varying the biasing force of the spring means.</p> |
