Resting heart rate: what’s normal and what moves it
The American Heart Association calls 60–100 bpm a normal adult resting heart rate. How to measure yours, what moves it, and when to see a doctor.
What is a good resting heart rate?
For adults, the American Heart Association describes a normal resting heart rate as 60 to 100 beats per minute. Fit people, especially endurance athletes, often sit lower, sometimes in the 40s. Resting heart rate is best measured in the morning before you get out of bed, and a trend over several days says more than any single reading.
How to measure your resting heart rate
- Measure before you get upTake the reading in the morning, before coffee and before getting out of bed.
- Find your pulsePlace two fingers on the inside of your wrist below the thumb, or at the side of your neck.
- Count for a minuteCount the beats for 60 seconds, or for 30 seconds and double it.
- Repeat for several morningsTake readings on three to five mornings and average them for a number you can trust.
Resting heart rate is how many times your heart beats per minute when you’re awake, still and relaxed. It’s one of the simplest measures you can take, with nothing but a clock. Most watches and rings now estimate it for you every day.
What counts as normal
The American Heart Association calls 60 to 100 beats per minute (bpm) normal for adults. That’s a wide band, because many things set your number: genetics, fitness, body size, medications, temperature and hydration. People who do a lot of aerobic training often sit below 60. Some well-trained endurance athletes rest in the 40s. In a fit person, a lower number usually reflects a heart that moves more blood with each beat, so it needs fewer beats.
Ways to measure it
| Method | How it works | What to expect |
|---|---|---|
| Manual pulse check | You count beats at the wrist or neck for a minute, ideally before getting up. | The classic definition. Takes a minute and needs no device. |
| Watch estimate from still periods | The watch picks out times when you’ve been still for several minutes and estimates your rate from them. | Apple Watch works roughly this way. It can differ from an overnight number. |
| Overnight average or low | A ring or band measures through the night and reports an average or the lowest stretch. | Often lower than a seated daytime reading. |
Every wearable number is an estimate. Optical sensors read blood flow through the skin, and accuracy drops with movement, a loose strap, tattoos or cold hands. Different methods give different numbers, so compare a device only with itself.
A worked example
Say your watch reports these resting rates over a week: 54, 55, 53, 61, 55, 54 and 56 bpm. The 61 came the morning after a late dinner and two drinks. Your weekly average is about 55 bpm, and the 61 is a one-off with an obvious cause. Now picture a different week where every reading sits between 60 and 63 for five days, with nothing in your routine to explain it. That sustained shift is the kind of trend worth noticing. It often lines up with short sleep, a hard block of training, heat, stress or a cold.
What moves it
- Fitness: Regular aerobic training tends to lower it over weeks and months.
- Sleep: Short or poor sleep tends to push it up the next day.
- Alcohol and late meals: Both commonly raise overnight heart rate.
- Caffeine and nicotine: Both can raise heart rate for hours.
- Heat and dehydration: Both make the heart work harder at rest.
- Stress and illness: Both tend to raise it while they last.
- Medications: Some lower heart rate and some raise it. Ask your doctor or pharmacist if a change worries you.
Trends, not single readings
One reading tells you little. A week or a month of readings tells you much more. Look at your average, and at how far today sits from it. Over months of consistent aerobic training, many people see their average drift down a few beats. A rise of a few beats for a few days is common and usually explained by sleep, alcohol, heat or hard training. Your HRV often moves the opposite way on the same days, which is why the two are read together.
When to see a doctor
A wearable is not a medical device. See a doctor if you have chest pain, fainting, shortness of breath or a heartbeat that feels irregular. See one too if your resting heart rate stays above 100 bpm, or if a low heart rate comes with dizziness, unusual tiredness or fainting. A low number on its own, in someone who trains and feels well, is common.
How FORM uses it
FORM reads resting heart rate from Apple Health or Health Connect, so any watch or ring that syncs there feeds it. It sits alongside HRV and sleep, and FORM’s recovery score is measured against your own 14-day baseline rather than a population chart. For a broader fitness marker from the same watch, see VO2 max.
FAQ
Is a resting heart rate of 50 normal?
The American Heart Association’s normal range starts at 60, but fit adults often rest around 50 or lower. If a low rate comes with dizziness, fainting or unusual tiredness, see a doctor.
Why is my resting heart rate higher than usual?
Short sleep, alcohol, late meals, heat, stress, caffeine and hard training are common reasons. If it stays above 100 bpm, or comes with symptoms, see a doctor.
Does a lower resting heart rate mean I’m fitter?
Often, but not always. Aerobic training tends to lower it, but genetics and medications play a large part too, so compare yourself with your own past readings.
Why does my watch show a different resting heart rate than my ring?
They measure at different times and in different ways, such as still periods during the day versus overnight. Compare each device only with itself.
