Abstract: An exercise device for strengthening the muscles of the pelvis, particularly the collective group of muscles involved in human sexual response, which are also important for controlling the evacuation of the intestines and the bladder. This exercise device focuses on increasing the strength, tone and endurance of these muscles. The device comprises a longitudinally extending member that includes a blunt head portion and a compressible shaft portion. The first end of the shaft portion is juxtaposed with the head portion. The first end of the shaft portion has an outwardly extending retaining slope formed thereon, particularly when the device is received within a pelvic body cavity and the muscles of the pelvic floor are at rest. The retaining slope is engageable with the retaining edge of the adjacent pelvic floor muscle platform of that pelvic body cavity to facilitate intracorporal retention within the pelvic body cavity.

Abstract: An exercise device for exercising of the abdominal muscles as well as in exercising the muscles of the upper torso, shoulders and arms while the back of the user is supported, elongated and stretched. The device includes a platform which is elevated at one end from a supporting surface for the device. A seat is located at the one end of the platform and a bowed back support member is disposed on the platform adjacent to the seat. The support member presents a convex curved surface of a longitudinal extent such that the back and head of the user can rest thereon with the user in a backwardly reclining posture. A belt fits around the waist of the user while a resilient or stretchable cord is adapted to engage the arms of the user during movement of the user from the backwardly reclining posture wherein the back of the user rests against the convex curved surface to a sitting position. The cord thus increases the force that must be exerted by the abdominal muscles of the user in carrying out this movement.
