What is the average resting heart rate (beats per minute)?

Explanation:
Resting heart rate is how many times the heart beats each minute when the body is at rest and not under stress. For healthy adults, the normal range is about 60 to 100 beats per minute, and the average value most sources cite is around 72 beats per minute. This makes 72 a good representative average for the general population. Some people, like well-trained athletes, may have resting rates closer to 60, while rates higher than 80 or 90 can occur due to factors like fitness level, illness, or stress. So 72 sits near the typical average.
