ABSTRACT:
An exercise device conveniently measures, monitors, and reports electromyograph (EMG) information to the user, for use in effectively strengthening selected muscles. The exercise device includes a sensor circuit responsive to electrical activity in tensioning muscles, and a control circuit responsive to an output signal produced by the sensor circuit. In a preferred embodiment the control circuit regulates an audio device, by attenuating the audio device output signal when the sensor output signal declines to below a preset threshold. Alternatively, the control circuit selectively activates an indication device, such as a vibrator, when the sensor output signal falls too low. The exercise device provides information as to muscle activity to the user in an entertaining fashion, and in a way that the user is not required to pay constant attention and refer to an output meter or other conventional display.
