A healthy resting pulse for adults falls between 60 and 100 beats per minute. During exercise, your pulse should climb higher, ideally reaching 50% to 85% of your maximum heart rate depending on how hard you’re working. Where your pulse sits within these ranges depends on your age, fitness level, and what you’re doing at the time.
Normal Resting Pulse by Age
Your resting heart rate is the number of times your heart beats per minute while you’re awake, calm, and sitting still. For adults 18 and older, the normal range is 60 to 100 bpm. Children have naturally faster hearts. Newborns can have a resting pulse as high as 205 bpm, and the range gradually narrows as kids grow: toddlers (1 to 3 years) typically fall between 98 and 140 bpm, school-age children (5 to 12) between 75 and 118 bpm, and adolescents (13 to 17) settle into the adult range of 60 to 100 bpm.
A lower resting pulse generally signals a more efficient heart. If your heart pumps more blood with each beat, it doesn’t need to beat as often to keep up with demand. That’s why physically fit people tend to have resting rates in the 50s or 60s, and well-trained endurance athletes often sit in the 40s. A study published in Circulation found that 38% of endurance athletes had minimum heart rates at or below 40 bpm on a 24-hour monitor, and about 2% dipped to 30 bpm or lower. In healthy, symptom-free athletes, rates this low are considered normal and well tolerated.
Your Pulse During Exercise
When you exercise, your pulse should rise well above its resting level. How high depends on your workout intensity and your age. The standard way to estimate your ceiling is simple: subtract your age from 220. A 40-year-old, for example, has an estimated maximum heart rate of 180 bpm.
From there, the American Heart Association breaks exercise into two intensity zones:
- Moderate intensity: 50% to 70% of your maximum heart rate. For that 40-year-old, this means keeping your pulse between roughly 90 and 126 bpm. Think brisk walking, casual cycling, or a light swim.
- Vigorous intensity: 70% to 85% of your maximum heart rate, or about 126 to 153 bpm for the same person. Running, fast cycling, and competitive sports fall here.
If you’re new to exercise, aim for the lower end of the moderate zone and build up over time. The general weekly target is about 2 hours and 30 minutes of moderate-intensity activity, or 1 hour and 15 minutes of vigorous activity.
When Your Pulse Is Too High
A resting heart rate consistently above 100 bpm is called tachycardia. This doesn’t always mean something is wrong. Your pulse can temporarily spike from caffeine, stress, dehydration, illness, or simply standing up quickly. But if your resting pulse stays elevated without an obvious cause, it’s worth paying attention to.
Symptoms that signal a problem alongside a fast pulse include a pounding or fluttering sensation in your chest, chest pain, shortness of breath, dizziness, lightheadedness, and fainting. Any combination of these with a rapid heart rate warrants prompt medical attention.
Caffeine is one of the more common culprits behind a pulse that runs higher than expected. Consuming more than 400 mg daily (roughly four standard cups of coffee) can raise both heart rate and blood pressure over time. People who regularly exceed 600 mg daily show elevated heart rates that persist even after resting, according to data reviewed by the American College of Cardiology.
What Affects Your Resting Pulse
Several everyday factors can push your resting pulse up or down temporarily. Caffeine, nicotine, and alcohol all raise it. So do stress, anxiety, pain, fever, and hot or humid weather. Dehydration forces your heart to work harder because there’s less blood volume to circulate, which bumps up your rate. Some medications, particularly stimulants and certain cold medicines, can do the same.
On the other side, regular aerobic exercise is the most reliable way to lower your resting pulse over time. As your cardiovascular fitness improves, your heart gets stronger and pumps more blood per beat, so it doesn’t need to beat as frequently. Sleep also brings your heart rate down, sometimes well below your waking resting rate.
How to Check Your Pulse Accurately
To get a reliable resting reading, sit down and rest quietly for a few minutes first. Place the tips of your index and middle fingers on the inside of your wrist, on the thumb side, between the bone and the tendon. Press lightly until you feel each beat. Pushing too hard can actually block blood flow and throw off your count.
You can also check at your neck by feeling for the artery on one side of your windpipe. Count beats for a full 60 seconds for the most accurate result. The shortcut of counting for 15 seconds and multiplying by four works in a pinch, but it can miss irregularities in your rhythm. If you’re using a smartwatch or fitness tracker, spot-check it against a manual count occasionally, since wrist-based sensors can lose accuracy during movement or if the band is loose.
For the most consistent comparison over time, check your pulse at the same time each day, ideally first thing in the morning before caffeine or physical activity.
