Heart Rate (HR) is the BEST measure of exercise intensity in a newly tested and exercising individual.
<h3>How is HR measured in exercise?</h3>
Steps to check your heart rate during exercise:
- 15 seconds are needed to take your pulse. Put index and third fingers on y neck, to the side of the windpipe, to check the pulse over the carotid artery.
- For a beats per minute calculation, multiply this number by 4.
Monitoring your heart rate while exercising can help you shed pounds or become more effective. This is due to the fact that heart rate is a reliable gauge of exercise intensity: Your heart rate increases as the intensity increases.
