What is the normal resting adult heart rate range in beats per minute?

• A. 40–60 bpm
• B. 60–100 bpm
• C. 100–140 bpm
• D. 50–70 bpm

Answer: (B)

Resting heart rate is the number of times the heart beats in a minute when you’re calm and not active. For most healthy adults, this rate typically ranges from 60 to 100 beats per minute. That range is used as the standard reference because it covers the normal variation seen in everyday life.

Some people, especially well-trained athletes, may have resting rates below 60 and still be healthy, but rates outside 60–100 are generally considered bradycardia or tachycardia in a resting state. The other options either fall below the typical lower limit, exceed the typical upper limit, or are too narrow to account for normal variation among adults.
