A good resting heart rate for adults falls between 60 and 100 beats per minute (bpm). Within that range, lower tends to be better. A resting rate in the 60s or 70s generally signals that your heart is pumping efficiently and doesn’t need to work as hard to circulate blood. Here’s what those numbers mean in practice and how age, fitness, and activity level shift what’s “good” for you.
Normal Resting Heart Rate by Age
The 60 to 100 bpm range applies to adults and adolescents, but children and infants have naturally faster heart rates because their hearts are smaller and need to beat more often to meet the body’s demands. These are typical resting ranges by age group:
- Newborns (birth to 4 weeks): 100 to 205 bpm
- Infants (4 weeks to 1 year): 100 to 180 bpm
- Toddlers (1 to 3 years): 98 to 140 bpm
- Preschool age (3 to 5 years): 80 to 120 bpm
- School age (5 to 12 years): 75 to 118 bpm
- Adolescents and adults (13+): 60 to 100 bpm
These numbers apply when someone is awake, calm, and sitting still. Heart rate drops during sleep and rises during any kind of physical activity, even walking around the house.
Why Lower Resting Rates Are Usually Better
A heart that beats 65 times per minute at rest is moving the same volume of blood as one beating 85 times per minute, just more efficiently per beat. That’s why aerobic fitness tends to push resting heart rate down over time. Well-trained endurance athletes often have resting rates in the 40s or 50s, and for them, that’s perfectly healthy. Their heart muscle is strong enough to pump a large volume of blood with each contraction, so it simply doesn’t need to beat as often.
For the average adult who isn’t a competitive athlete, a resting rate consistently in the 60s or low 70s is a solid sign of cardiovascular fitness. If your resting rate sits in the upper 80s or 90s, it’s still within the normal range, but it may be worth paying attention to. Consistently elevated resting heart rates have been linked to higher cardiovascular strain over time, and regular aerobic exercise is one of the most reliable ways to bring that number down.
When Heart Rate Is Too Fast or Too Slow
A resting heart rate above 100 bpm in an adult is called tachycardia. It doesn’t always mean something is wrong. Anxiety, caffeine, dehydration, fever, or simply standing up quickly can push your rate past 100 temporarily. But if your resting rate stays above 100 without an obvious cause, it’s worth investigating, because it can sometimes reflect an underlying heart rhythm issue or thyroid problem.
On the other end, a resting rate below 60 bpm is called bradycardia. In fit individuals, this is normal and expected. In someone who isn’t physically active, though, a rate consistently below 60 can sometimes cause dizziness, fatigue, or shortness of breath if the heart isn’t pumping enough blood to meet the body’s needs. The number alone doesn’t tell the full story. What matters is whether symptoms accompany it.
What Affects Your Resting Heart Rate
Your resting bpm isn’t a fixed number. It shifts throughout the day and across weeks depending on several factors. Stress and anxiety activate your body’s fight-or-flight response, which speeds the heart up. Caffeine does the same by stimulating your nervous system. Dehydration reduces blood volume, forcing the heart to beat faster to compensate. Hot environments raise heart rate because your body works harder to cool itself.
Medications play a role too. Some cold medicines and asthma inhalers can raise heart rate, while blood pressure medications often lower it. Hormonal changes, illness, and poor sleep also cause fluctuations. For the most accurate reading, check your pulse first thing in the morning before getting out of bed, after a calm night of sleep, and before any caffeine.
Heart Rate During Exercise
A “good” bpm during a workout is different from a good resting rate. The goal during exercise is to push your heart rate into a target zone based on your estimated maximum heart rate. The simplest formula for maximum heart rate is 220 minus your age. A more accurate version, sometimes called the Tanaka formula, is 208 minus (0.7 times your age). For a 40-year-old, that gives an estimated max of about 180 bpm.
From there, exercise intensity zones are calculated as percentages of that maximum. Moderate-intensity exercise, like brisk walking or easy cycling, typically falls between about 50% and 70% of your max. For that same 40-year-old, moderate intensity means keeping the heart rate roughly between 90 and 126 bpm. Vigorous exercise, like running or high-intensity interval training, pushes you into the 70% to 85% range, or about 126 to 153 bpm in this example.
These zones matter because staying in the moderate range builds aerobic endurance and burns fat efficiently, while vigorous zones improve cardiovascular capacity and performance. You don’t need to hit your maximum heart rate during a workout, and doing so regularly can be counterproductive. Most fitness benefits come from sustained effort in the moderate to vigorous zones.
How to Check Your Heart Rate
The easiest method is placing two fingers (index and middle) on the inside of your wrist, just below the base of your thumb. Count the beats for 15 seconds and multiply by four. That gives your bpm. You can also feel for your pulse on the side of your neck, just below the jawline.
Fitness trackers and smartwatches use optical sensors to estimate heart rate continuously. They’re reasonably accurate for resting measurements and general trends, though they can be less precise during intense exercise or if the watch fits loosely. For a reliable baseline, take your resting heart rate manually a few mornings in a row and average the results. Tracking that number over weeks or months gives you a useful picture of your cardiovascular fitness and whether it’s improving.
