A usual heart rate in case of adults varies from 60 to 100 beats per minute. Usually, a lower heart rate at rest signifies more effective functioning of heart and better cardiovascular fitness. For example, a well-trained athlete may possess a usual resting heart rate closer to 40 beats in a minute.

3. Feel a pulse.
4. Count for 10 seconds.
5. Multiply by 6.
