Explanation:
Detailed explanation-1: -Your heart rate will increase in proportion to the intensity of your exercise. You can track and guide your exercise intensity by calculating your Target Heart Rate (THR) range. For moderate-intensity physical activity, a person’s THR should be 50 to 70 per cent of their maximum heart rate.
