Your heart rate is the number of times your heart beats in one minute, and you can measure it in about 60 seconds with nothing but two fingers. A normal resting heart rate for adults falls between 60 and 100 beats per minute (bpm). Knowing yours, and how to check it accurately, gives you a simple window into your cardiovascular health and fitness level.
How to Check Your Pulse by Hand
The two easiest places to feel your pulse are your wrist and your neck. At the wrist, place the tips of your index and middle fingers on the thumb side, right in the soft spot between the bone and the tendon. At the neck, press those same two fingertips gently into the groove beside your windpipe. Don’t use your thumb, which has its own pulse and can throw off your count.
Once you feel a steady beat, count the number of pulses for a full 60 seconds. That number is your heart rate. If you’re in a hurry, count for 15 seconds and multiply by four. The full 60-second count is more accurate, especially if your heartbeat is irregular, since a short count can amplify small errors.
For the most reliable resting heart rate, measure first thing in the morning before you get out of bed, or after sitting quietly for at least five minutes. Caffeine, stress, and even standing up can push the number higher than your true baseline.
What a Normal Resting Heart Rate Looks Like
For adults, 60 to 100 bpm at rest is considered the normal range. Well-trained athletes often sit much lower, sometimes around 40 bpm, because a stronger heart pumps more blood per beat and doesn’t need to work as hard. A resting rate consistently above 100 bpm (a condition called tachycardia) or below 60 bpm in someone who isn’t particularly fit (bradycardia) is worth discussing with a doctor.
Children have naturally faster hearts. CDC data from a large national survey show the following average resting rates by age:
- Under 1 year: about 129 bpm (typically ranging from 103 to 156)
- 1 year: about 118 bpm
- 2 to 3 years: about 107 bpm
- 4 to 5 years: about 96 bpm
- 6 to 8 years: about 87 bpm
- 9 to 11 years: about 83 bpm
By the early teen years, heart rates settle into the adult range.
Using a Device Instead
Wrist-based fitness trackers and smartwatches use optical sensors that shine light into the skin and detect blood flow changes. They’re convenient for 24-hour monitoring and spotting trends, but they’re less accurate during vigorous movement or if the band fits loosely. Chest strap monitors, which detect the heart’s electrical signal directly, tend to be more precise during intense exercise.
If you’re using a smartwatch to track resting heart rate, the most useful number is the one recorded overnight or first thing in the morning. Many devices report this automatically. A sudden upward shift of 5 to 10 bpm from your personal baseline can signal stress, dehydration, illness, or poor sleep, even before you feel symptoms.
Heart Rate During Exercise
During a workout, your heart rate tells you how hard your cardiovascular system is working. Exercise intensity is usually described as a percentage of your maximum heart rate. The most common formula for estimating your max is 220 minus your age. So a 40-year-old would have an estimated maximum of 180 bpm.
That formula is a rough guide, not a precise measurement. Studies comparing predicted maximums to actual maximums during exercise testing have found the formula consistently overestimates by several beats, and individual variation is wide. It’s still useful as a starting point, but if the number feels off compared to how your body responds during hard effort, trust your body.
The American Heart Association breaks exercise intensity into two main zones based on your estimated max:
- Moderate intensity: 50% to 70% of maximum heart rate
- Vigorous intensity: 70% to 85% of maximum heart rate
For that 40-year-old with an estimated max of 180, moderate exercise would mean keeping the heart rate between 90 and 126 bpm, while vigorous exercise would fall between 126 and 153 bpm. Moderate intensity feels like a brisk walk where you can hold a conversation but not sing. Vigorous intensity feels like you can only get out a few words between breaths.
What Your Heart Rate Can Tell You
A single reading is a snapshot. The real value comes from tracking your heart rate over time. A gradually decreasing resting heart rate usually signals improving cardiovascular fitness. A resting rate that creeps upward over weeks or months, without an obvious cause like increased stress or a new medication, can be a sign that something deserves attention.
Pay attention to how quickly your heart rate drops after exercise, too. A healthy heart recovers fast. If your rate drops by 20 or more bpm within the first minute after stopping vigorous exercise, that’s a good sign of cardiovascular fitness. A slow recovery, where your heart stays elevated for several minutes, can indicate lower fitness or, in some cases, an underlying heart issue.
Your heart rate also responds to things that have nothing to do with exercise. Dehydration, fever, anxiety, alcohol, and poor sleep all push it higher. Tracking the pattern helps you separate a one-off reading from a meaningful change.
