What is heart rate?
Heart rate is often measured in Beats Per Min (BPM), refers to how many times our heart beat in one min (60s). Normal resting heart rate is about 60-80 bpm. Exercise heart rate is often higher than this range. We can measure HR by placing our index and middle fingers on our carotid pulse or radial pulse. Modern technology had allow us to measure it by Heart Rate Monitors (HRM), which comes in the form of watch and a chest strap. Popular brands for HRM are Polar, Timex, Sunnto, Garmin and New Balance.
