Heart Rate Recovery Calculator
Heart Rate Recovery (HRR) is a simple yet powerful metric that measures how quickly your heart rate drops after strenuous exercise. A faster heart rate recovery is generally associated with better cardiovascular fitness and a stronger heart. To calculate HRR, you need to know your heart rate at the peak of your exercise and your heart rate one minute after you stop exercising.
Your Heart Rate Recovery:
Understanding Your Results
Your Heart Rate Recovery (HRR) is calculated by subtracting your heart rate one minute after exercise from your peak heart rate during exercise. A higher HRR value generally indicates better cardiovascular health.
- Excellent: 42 bpm or higher
- Good: 32 to 41 bpm
- Average: 22 to 31 bpm
- Poor: Less than 21 bpm
Example: If your peak heart rate during a tough workout was 170 bpm and one minute after stopping, your heart rate dropped to 110 bpm, your HRR would be 170 – 110 = 60 bpm. This would be considered excellent heart rate recovery.
