Abstract

Abstract An isometric vaginal exercise device includes a rounded shaft having a flange attached to one end thereof. The shaft has a concave portion adjacent the flange, wherein the diameter of the concave portion decreases to a minimum value and then increases to a maximum value with increasing distance from the flange along the shaft, whereby the concave portion allows more effective gripping of the isometric vaginal exercise device by perivaginal muscles of the user. The flange is substantially oval to permit convenient accommodation between the legs of the user. A handle is attached to the flange end of the isometric vaginal exercise device. A method of using the isometric device to improve muscle tone of the muscles of the pelvic diaphragm is disclosed.
