An exercise machine or device for progressively and increasingly strengthening the muscles of normal subjects associated with the limb extremity digits or phlanges, i.e., the fingers and toes. The basic component comprises a limb extremity platform and, coupled thereto by suitable pivot or hinge structure, a forward, movable digits' support member essentially disposed in the same plane as said platform, when disposed in a normal or medial-point operative position. Means for resisting digits' pressure upon the digit support member is connected thereto at an outer margin thereof, such structure generally comprising a flexible elongate connector such as a cable which is routed over a support pulley. The remaining extremity of the connector will generally be associated with weight means, generally permitting differential loading in small pound increments, e.g., one to five pounds. The machine or device is usable for strengthening the muscles of either the fingers or toes of the user. In one form of the invention, the juncture between the limb extremity platform and the foot digits' support member is arcuate and corresponds generally to a locus passing through the metataursal phalangeal joints, at least the central forward portion of the platform being convex and being received by a corresponding concave portion as to the digits' support member.
