A good resting heart rate for adults falls between 60 and 100 beats per minute (bpm). Lower within that range generally signals a more efficient heart. Highly trained endurance athletes can have healthy resting rates as low as 40 bpm, while most people who exercise regularly settle somewhere in the 50s or 60s.
Normal Resting Heart Rate by Age
Heart rate changes dramatically from infancy through adolescence, then stabilizes in adulthood. Newborns to 3-month-olds have awake heart rates of 85 to 205 bpm because their small hearts need to beat much faster to circulate enough blood. Between 3 months and 2 years, that range is 100 to 190 bpm while awake. Children ages 2 to 10 settle into 60 to 140 bpm, and by age 10 the adult range of 60 to 100 bpm takes hold and stays there for the rest of your life.
Sleep naturally lowers heart rate. A child between 2 and 10 might drop to 60 to 90 bpm during sleep, while adults and older children typically fall to 50 to 90 bpm overnight. If you check your pulse first thing in the morning before getting out of bed, expect a number near the bottom of your usual range.
Why a Lower Resting Rate Is Usually Better
When your heart is strong and efficient, it pushes out more blood with each beat. That means it doesn’t need to beat as often to deliver the same amount of oxygen. Regular cardiovascular exercise over months and years physically increases the heart’s size and the force of each contraction. The heart also spends more time filling with blood between beats, which improves output further.
This is why endurance athletes commonly have resting rates in the 40s or low 50s without any health problems. Their nervous systems also adapt: the branch responsible for “rest and digest” functions becomes more active, keeping the heart in a calm, slower rhythm at rest. For non-athletes, a resting rate that gradually drops from, say, 78 to 65 over several months of consistent exercise is a reliable sign of improving cardiovascular fitness.
When Heart Rate Is Too Low or Too High
A resting heart rate below 60 bpm is technically called bradycardia. In fit people, this is harmless. It becomes a concern when it causes symptoms like dizziness, fainting, confusion, chest pain, or extreme fatigue. If you’re not an athlete and your resting rate consistently sits below 60, it’s worth mentioning to a doctor.
On the other end, a resting rate consistently above 100 bpm (tachycardia) puts extra strain on the heart over time. Symptoms of a dangerously fast rate include chest pain, shortness of breath, lightheadedness, and feeling like your heart is pounding or fluttering. In people with otherwise healthy hearts, serious symptoms are uncommon unless the rate climbs above 150 bpm, but those with existing heart conditions can feel the effects at lower rates.
What Affects Your Resting Heart Rate
Several everyday factors can push your heart rate up or down, sometimes enough to make a normal reading look abnormal. Caffeine stimulates the nervous system and can speed up your heart rate or trigger irregular rhythms in sensitive individuals. Alcohol has a similar effect, increasing nervous system activity and shortening the electrical cycles in the heart’s upper chambers.
Certain medications also change heart rate significantly. Beta blockers, commonly prescribed for high blood pressure and anxiety, deliberately slow the heart and can bring resting rates into the 50s or lower. Other blood pressure medications, some heart rhythm drugs, and even certain eye drops can have the same effect. Asthma inhalers, decongestants, and thyroid medications tend to push heart rate higher. Stress, dehydration, fever, and poor sleep all raise resting heart rate temporarily too.
Because so many things influence the number, the best way to track your true resting rate is to measure it at the same time each day, ideally in the morning before coffee or activity.
How to Check Your Pulse
Sit down and rest quietly for a few minutes before measuring. You can find your pulse in two places: your wrist or your neck.
For a wrist reading, turn one hand palm-up. Place the tips of your index and middle fingers from the other hand on the thumb side of your wrist, in the soft groove between the wrist bone and the tendon. Press lightly until you feel a steady beat. Pressing too hard can actually block blood flow and make the pulse harder to detect.
For a neck reading, place two fingertips in the groove beside your windpipe on one side. Never press both sides of your neck at the same time, as this can cause dizziness or fainting. Once you feel a consistent beat, count the number of pulses over 60 seconds using a watch or timer. A quicker method is to count for 15 seconds and multiply by four, though the full 60-second count is more accurate, especially if your rhythm feels uneven.
Target Heart Rate During Exercise
Your heart rate during a workout tells you how hard your cardiovascular system is actually working, regardless of how the effort feels. Exercise heart rate is measured as a percentage of your maximum heart rate, which you can estimate with a simple formula: 220 minus your age. A 40-year-old, for example, has an estimated max of 180 bpm. A slightly more precise formula is 206.9 minus (0.67 times your age), which gives that same 40-year-old an estimated max of about 180 as well, though the two formulas diverge more at younger and older ages.
Moderate-intensity exercise, like brisk walking or an easy bike ride, puts you at 50 to 70% of your max. For a 40-year-old, that’s roughly 90 to 126 bpm. Vigorous exercise, like running or high-intensity interval training, pushes you to 70 to 85% of max, or about 126 to 153 bpm in the same person. Staying in these zones helps ensure you’re working hard enough to build fitness without overexerting yourself.
Heart Rate Recovery as a Fitness Marker
How quickly your heart rate drops after intense exercise is one of the best indicators of cardiovascular health. This is called heart rate recovery. After stopping vigorous activity, a healthy heart should slow down by at least 18 beats within the first minute of rest. A faster drop signals that your nervous system efficiently switches from “go” mode back to “rest” mode. A sluggish recovery, where your heart rate barely budges in that first minute, can suggest your cardiovascular system is under strain and may benefit from more consistent aerobic training.
You can test this yourself: note your heart rate immediately after finishing a hard workout, then check it again exactly one minute later. Subtract the second number from the first. Tracking this over weeks or months gives you a practical measure of whether your fitness is improving.
Heart Rate Variability
Beyond the beats-per-minute number, the tiny fluctuations in timing between individual heartbeats also matter. This is called heart rate variability, or HRV, and most fitness watches and chest straps now track it. HRV measures the variation in milliseconds between consecutive beats. A higher HRV generally means your body recovers from stress more effectively and your nervous system is flexible and responsive.
HRV naturally declines with age. A person in their 20s typically has an HRV between 55 and 105 milliseconds, while someone in their 60s might range from 25 to 45 milliseconds. Within your age group, a higher number is generally more desirable. Consistent exercise, quality sleep, and lower stress levels all tend to push HRV upward over time, while illness, overtraining, poor sleep, and chronic stress bring it down. Many people use daily HRV readings to decide whether to train hard or take a recovery day.
