What you need: nothing β just your heart rate at peak effort and again exactly 1 minute into rest (a watch/phone timer and a wearable or manual pulse check).
Heart Rate Recovery (HRR) Calculator
How to use this calculator
After a bout of intense exertion (e.g. running, cycling, or 1 minute of hard bodyweight exercise), note your heart rate at the peak, then stop and stay still β note your heart rate again at exactly 1 minute of passive rest.
What your result means
Heart Rate Recovery reflects how quickly your parasympathetic ("rest and recover") nervous system reactivates after exertion. A drop of less than 12 bpm in the first minute is an established, independent predictor of higher mortality risk in the foundational Cleveland Clinic research (Cole et al., 1999), even after adjusting for other risk factors β a bigger drop generally reflects better cardiovascular fitness.
"Ran this after my usual cardio session β nice to attach a number to how fit my recovery actually is."

"The 1999 study citation made me trust this more than a random fitness-app metric."

Questions and answers
What is heart rate recovery?
Heart rate recovery is how much your heart rate falls after you stop exercising, often measured after one minute. In research, a slower drop is associated with higher cardiovascular risk.
How do I measure it?
Use a heart-rate monitor at the end of exercise and again one minute later, then enter both values.
