ABSTRACT:
A device for exercising the abdominal muscles and method comprising an informing unit having a sensor, an announciator with a signal-controlling circuit board and a signal reproducer, and elements to enable positioning and retaining the informing unit on the user's belly. The abdominal muscles are exercised by flexing them using the information from the sensor. These attract the user's attention to the exercising of abdominal muscles, by reproducing an exercise command or musical note, serving to indicate to the user to contract muscles, and stop the command, therefore resulting in more efficient development of the abdominal muscles.
