Heart rate recovery (HRR) measures how quickly your heart rate drops in the first minute after you stop exercising. A faster drop generally reflects better cardiovascular fitness and autonomic nervous system function — it's a genuinely useful, well-studied fitness marker, distinct from your target training zones.
Your measurements
Check your pulse (or use a heart rate monitor) immediately after stopping vigorous exercise, then again exactly one minute later during a light rest or gentle cool-down.
This is a simplified, informal measurement, not a supervised clinical stress test. Treat a low number as a general fitness signal, not a diagnosis, and talk to a doctor about any concerns.
How it works
Exercise vigorously for several minutes to raise your heart rate.
Check your heart rate immediately when you stop (your peak).
Rest for exactly one minute, then check it again.
We calculate the difference — the bigger the drop, the more efficiently your cardiovascular system recovers.
Consistency matters more than any single reading. Track this over weeks as your fitness changes, using the same general exercise intensity each time.
Frequently asked questions
How much your heart rate drops in the minute after you stop exercising. A faster drop generally indicates better cardiovascular fitness and more efficient autonomic nervous system function.
Right after finishing vigorous exercise, check your heart rate (peak HR). Rest for exactly one minute (a light cool-down is fine) and check it again. The difference is your 1-minute heart rate recovery.
General fitness references often use: below 12 bpm is below average, 12-20 bpm is average, 21-30 bpm is good, and above 30 bpm is excellent.
Research has linked slow recovery (using clinical exercise-test protocols) to increased cardiovascular risk. This calculator uses a simplified, informal measurement, not a clinical stress test — treat a low number as a general fitness signal, not a diagnosis.
