Heart rate recovery is the fall in heart rate over a specified period after exercise. To calculate it, subtract the later reading from the starting reading used by your measurement protocol. A starting value of 160 beats per minute and a one-minute value of 132 gives a one-minute recovery of 28 bpm.
The calculation is simple. Getting comparable readings takes more care. Timing, the starting point, your cooldown and the device all matter. Use the feature as a way to understand consistently recorded workouts, not as a home diagnosis or a reason to perform an unsupervised maximal exercise test.
This article explains a measurement, not a cardiac screening test. Follow your normal exercise and cooldown advice. New concerning symptoms need clinical assessment, not another workout to test your recovery score.
What does heart rate recovery measure?
It describes how far heart rate falls after exercise over a stated interval. Research links the early recovery pattern with autonomic regulation, including vagal reactivation, but an app number does not identify a person’s medical condition (Imai et al., 1994).
It is also different from a training zone. Our heart-rate zones guide covers how heart rate is used during exercise. Recovery is about what happens afterwards under a specified recording method.
Be precise with the abbreviation. Here, HRR means heart rate recovery. In other fitness material, the same letters may refer to heart rate reserve, a different calculation. Check the definition rather than assuming two numbers labelled HRR describe the same thing.
What is the calculation?
Recovery at a stated interval = protocol starting heart rate − heart rate at that interval.
Clinical papers often use peak exercise heart rate as the starting value. An everyday device feature may define its measurement window differently. Read its instructions and record what it actually uses. Do not substitute the highest value from much earlier in a workout without checking the method.
| Time point | Example reading | Recovery from the stated start |
|---|---|---|
| Protocol starting point | 160 bpm | Starting reference |
| 60 seconds later | 132 bpm | 160 − 132 = 28 bpm |
| 120 seconds later | 120 bpm | 160 − 120 = 40 bpm |
The fall from the first-minute reading to the second-minute reading is 12 bpm in this example. That is not the same as the total two-minute recovery of 40 bpm. State which quantity you are reporting.
How can you record it during an ordinary training routine?
Use your device’s recovery function if available, following its current instructions and your usual safe cooldown. Do not abruptly stop or change a prescribed cooldown simply to improve the number.
- Choose an ordinary workout you can compare with similar sessions.
- Check how the device defines the start and interval.
- Keep the exercise finish and cooldown method consistent.
- Record the stated starting value and the later readings.
- Subtract, label the interval and note any unusual conditions.
Our Garmin fitness-tracker comparison can help with device choices. Features and menus vary across models, so use the instructions for the watch you actually own rather than assuming every Garmin records recovery identically.
Why can two readings disagree?
First check whether the comparison is fair. One device might start its timer at a different moment, or one recording might include a walking cooldown while another uses a different recovery posture. A delayed manual reading also changes the interval being measured.
Sensor quality is another consideration. Wrist-optical measurements can be affected by device and measurement conditions; evidence from older devices is not a guarantee about a current model (Bent et al., 2020).
A useful log includes workout type, duration, starting value, recovery interval, cooldown method, device and unusual conditions. Keep the entries descriptive rather than turning each session into a pass or fail.
What is a good heart rate recovery?
There is no single number that should be applied to every home workout. Published thresholds belong to their particular test protocols and populations. Cole and colleagues studied adults referred for clinical exercise testing; their findings were not a universal grading system for recreational runners using different apps (Cole et al., 1999).
Shetler and colleagues also examined methodological issues and different recovery intervals in a clinical population. Their work supports recording the method, not treating one-minute and two-minute values as interchangeable (Shetler et al., 2001).
If you are following a clinical rehabilitation or exercise-testing plan, use the interpretation provided by that team. If you are tracking ordinary workouts, discuss a persistent concerning change with a clinician rather than diagnosing it from an internet chart.
How should you use the trend?
Compare like with like. A hot hilly race and a short easy indoor session are poor candidates for a direct comparison. Our Zone 2 training guide helps explain why exercise intensity is useful context when looking back over a training week.
A trend is only as useful as its recording consistency. Note illness, an unusual session or a changed device instead of quietly combining those entries into one average. Medication and health questions belong with your clinician; do not alter treatment to change a wearable reading.
Different wearables may serve different purposes. Our smart-ring guide covers options for a broader monitoring routine. Do not assume a ring provides the same live recovery measurement or exercise feedback as a particular watch.
Frequently asked questions
Is heart rate recovery the same as HRV?
No. Heart rate recovery describes the fall in heart rate after exercise over an interval. Heart rate variability describes variation between individual heartbeats. Check which metric an app is displaying.
Do I subtract the second minute from the first minute?
Not when calculating total two-minute recovery from the stated starting value. Use the same start for both intervals, unless your protocol explicitly defines another calculation.
Should I stop completely to get a better result?
Do not change your normal safe cooldown just to alter the number. Follow the measurement instructions and any exercise advice, and compare sessions with the same method.
Does a low result prove poor heart health?
No. A home reading is not a diagnosis. Interpretation depends on the protocol, population and clinical context. Discuss persistent concerns or symptoms with a clinician.
Why did my score change after switching watches?
The timing, sensor, processing or definition may differ. Check both devices' instructions before combining old and new readings into one trend.
