You can get your heart rate in about 15 seconds using nothing more than two fingers and a clock. Place the tips of your index and middle fingers on the inside of your wrist, just below the base of your thumb, and count the beats you feel. Multiply that count by four to get your beats per minute (bpm). That’s the core technique, but there are a few details worth knowing to get an accurate reading every time.
Taking Your Pulse at the Wrist
The wrist is the easiest and safest place to check your heart rate. Turn one hand palm-up and place the tips of your index and middle fingers on the inner wrist, just below the thumb side. You’re feeling for the radial artery, which runs close to the surface there. Press lightly until you feel a steady tapping. Pressing too hard can actually block blood flow and make the pulse harder to detect.
Don’t use your thumb. It has its own pulse, which can interfere with your count.
Once you feel the beats clearly, watch a clock and count for 15 seconds, then multiply by four. If you want more precision, or if the rhythm feels uneven, count for a full 60 seconds instead.
Taking Your Pulse at the Neck
Your neck offers a stronger pulse that’s easier to find during exercise or when your wrist pulse feels faint. Place your index and middle fingers in the groove beside your windpipe, on one side only. You’ll feel the carotid artery pulsing there. Use the same light pressure and counting method as the wrist.
A few safety rules apply here. Never press on both sides of your neck at the same time, as this can make you dizzy, lightheaded, or even cause you to faint. If you’ve ever been told you have plaque buildup in your neck arteries, skip this location entirely and use your wrist instead.
Using a Device
If you’d rather not count beats manually, most fitness trackers, smartwatches, and phone apps use optical sensors to read your pulse continuously. These work by shining light into the skin and detecting changes in blood flow. For a quick spot check, a fingertip pulse oximeter (the clip-on device you’ve likely seen at a doctor’s office) gives a reading in seconds and is widely available at pharmacies for under $30.
Wrist-based wearables are generally reliable at rest but can lose accuracy during high-intensity movement, especially if the band is loose. Chest strap monitors tend to be more precise during vigorous exercise because they detect the electrical signal of each heartbeat rather than relying on light.
What a Normal Resting Heart Rate Looks Like
For adults (18 and older), a normal resting heart rate falls between 60 and 100 bpm. That range holds for adolescents aged 13 to 17 as well. Children have naturally faster hearts: a toddler’s resting rate can run between 98 and 140 bpm, while school-age kids (5 to 12) typically fall between 75 and 118 bpm.
A resting rate below 60 bpm is technically called bradycardia, and above 100 bpm is called tachycardia. Neither number is automatically a problem. Well-trained athletes often have resting rates in the 40s or 50s because their hearts pump more blood per beat. On the other hand, a rate consistently above 100 at rest, or below 60 with symptoms like dizziness or fatigue, is worth looking into.
Getting an Accurate Resting Reading
Your heart rate shifts constantly based on what your body is doing, so “resting” heart rate requires actual rest. For the most reliable number, check your pulse first thing in the morning before getting out of bed. If that’s not practical, sit quietly for at least five minutes before measuring. Avoid checking right after caffeine, exercise, or a stressful moment.
Several things can push your resting rate higher or lower on any given day. Caffeine and decongestants speed it up. Certain prescription medications slow it down, most notably beta-blockers, which work by blocking stress hormones from reaching your heart. Dehydration, anxiety, fever, and poor sleep all raise it. Tracking your pulse at the same time each day over a week or two gives you a much more useful baseline than any single reading.
Finding Your Target Heart Rate for Exercise
If you’re checking your heart rate during workouts, it helps to know what zone you’re aiming for. The standard approach starts with estimating your maximum heart rate: subtract your age from 220. A 40-year-old, for example, has an estimated max of 180 bpm.
A more personalized method, sometimes called the Karvonen formula, factors in your resting heart rate to find what’s called your heart rate reserve. Here’s how it works:
- Step 1: Subtract your age from 220 to estimate your maximum heart rate.
- Step 2: Subtract your resting heart rate from that number. The result is your heart rate reserve.
- Step 3: Multiply the reserve by the intensity you want (0.60 for moderate, 0.80 for vigorous).
- Step 4: Add your resting heart rate back to that number. The result is your target heart rate.
For a 40-year-old with a resting heart rate of 70, moderate intensity (60%) would look like this: 220 minus 40 equals 180, minus 70 equals 110 (the reserve), times 0.60 equals 66, plus 70 equals 136 bpm. The American College of Sports Medicine recommends exercising at 60 to 80 percent of your heart rate reserve for general cardiovascular fitness.
Checking Your Heart Rate Recovery
Heart rate recovery is how quickly your pulse drops after you stop exercising, and it’s a useful indicator of cardiovascular fitness. To check it, note your heart rate immediately when you finish vigorous exercise, then sit or stand still for one minute and check again. The difference between those two numbers is your recovery rate.
A drop of 18 beats or more in the first minute is considered a good recovery. A smaller drop may simply reflect lower fitness levels, but consistently poor recovery over time, even as fitness improves, is worth mentioning to a healthcare provider. As you get fitter, you’ll typically see this number improve.
What Your Pulse Rhythm Tells You
While counting beats, pay attention to the rhythm itself. A healthy pulse feels steady and even, like a metronome. Occasional skipped beats or extra beats are common and usually harmless, especially if they happen once or twice during a 60-second count.
A pulse that feels consistently irregular, with beats coming at unpredictable intervals, is a different story. This pattern can indicate an irregular heart rhythm like atrial fibrillation, which affects millions of adults and often goes undetected. If you notice a persistently uneven rhythm each time you check, that’s a finding worth bringing up at your next appointment. Some smartwatches now flag irregular rhythms automatically, but a manual check can pick up the same information if you’re paying attention to the spacing between beats rather than just the count.
