A wafer-like alert unit is disclosed which is affixed to a body surface in a private and discrete manner and provides a private or silent stimulus such as a vibrational signal to the user at selected time intervals to remind the user to flex adjacent muscle groups or to perform isometric exercise. The alert unit is designed to be worn imperceptibly to the public and provide a private and discrete way to maintain an exercise regimen without any wires or bulky control boxes. The alert unit is mounted directly to the body using adhesive or alternatively fitted in a self-adhesive pouch or pocket which is then secured to the body. The alert unit may also be inserted into a fabric pouch that is sewn into an undergarment which is then worn in the normal manner. The alert unit includes a power source such as a battery, a motor which creates a vibrational signal, a power switch, a timer, and means for inputting variable interval settings to allow the user to tailor his or her exercise regimen as needed. At selected time intervals the alert unit sends a vibrational signal to the adjacent body surface, which reminds the user to flex the muscles for a given number of repetitions. Several alert units can be combined into a system in which different body surface are exercised at different intervals or different times.
