Abstract
Abstract An abdominal muscle firmness alarm is characterized by a control unit containing a mechanism for producing a signal in the form of an electrical charge or a vibration impulse; a switch for controlling operation; a timer for selecting the interval between the transmitted signals; and, discs interconnecting the control unit and selectively affixed to the wearer's abdominal region over the Rectus muscles. When the wearer senses the signal through the aforesaid discs, the wearer is reminded to contract the muscles of the abdomen, increasing the muscle tone of the latter and serving restoring and abdomen flattening purposes.
