Abstract: The objective of this invention is to provide an exercise aid device which can be used for various kinds of exercise and which enables the user to perform aerobic exercise safely and comfortably at the level best suited to that person, and a method which employs this device. In order to achieve this object, the level of intensity of aerobic exercise which is most suitable for the person is considered to be 80% of the AT (Anaerobic Threshold) value as determined by analyzing the pulse rate while that person is exercising. The pulse wave is detected by this headphone-type exercise aid device. The pulse rate is measured at the superficial temporal artery, which is near the right ear. The pulse wave is detected by a sensor of either an optical sensor or an ultrasonic blood velocity meter. Once the optimal exercise is calculated, it is transmitted to the exerciser as the corresponding rhythm through the fitness headphone for maintaining the optimal exercise.
