Resting Heart Rate (RHR) Calculator

Check your cardiovascular fitness by calculating your Resting Heart Rate (RHR) and see how you rank based on American Heart Association guidelines.

What is Resting Heart Rate?

[cite_start]

Resting Heart Rate (RHR) is the number of times your heart beats per minute (bpm) while you are at complete rest[cite: 9]. [cite_start]It's a key indicator of your overall cardiovascular fitness and heart health[cite: 10]. Measuring it regularly can provide valuable insights into how your body is functioning.

Understanding Your RHR

Category Heart Rate (bpm)
Normal Range (Adults)60–100 bpm
Conditioned Athletes40–60 bpm

An athlete's heart muscle is stronger and more efficient, so it needs to beat fewer times to pump the same amount of blood.

Why It Matters

  • A lower RHR generally indicates better cardiovascular fitness and a more efficient heart.
  • An elevated RHR can be a temporary sign of stress, dehydration, or illness. [cite_start]Persistently high RHR may indicate underlying heart issues[cite: 17].

Disclaimer: For the most accurate reading, measure your RHR in the morning after a good night's sleep and before getting out of bed. [cite_start]Always consult a doctor for medical advice[cite: 18].
