Your heart is a muscle that never gets a day off. It beats about 100,000 times every single day, pushing blood through miles of vessels to keep your organs alive and your brain thinking. But when you’re sitting on the couch or finishing a run and you feel that rhythmic thumping in your neck, you might start wondering what’s your pulse supposed to be? It's a question that sounds simple but actually has a lot of "it depends" attached to it.
Most people think there’s just one perfect number. There isn't.
If you look at the official guidelines from the American Heart Association (AHA), they’ll tell you a normal resting heart rate for adults ranges from 60 to 100 beats per minute (bpm). That’s a huge window. Someone at 61 bpm and someone at 99 bpm are both technically "normal," yet their cardiovascular fitness levels might be worlds apart. It’s kinda like saying a normal car speed is between 20 and 70 miles per hour—it’s true, but context matters.
Breaking Down The Resting Heart Rate
So, what’s your pulse supposed to be when you’re just chilling? For most healthy adults, you actually want to see that number on the lower end of that 60-100 range. When your heart is efficient, it doesn’t have to beat as often to move the same amount of blood. Think of it like a heavy-duty truck engine versus a tiny sedan engine; the big engine can do the work with fewer revs.
Elite athletes often have resting pulses in the 40s or 50s. Miguel Induráin, a legendary cyclist, famously had a resting heart rate of 28 bpm. That is extreme. For the average person, being in the 60s or 70s is a great sign of heart health. If you’re consistently sitting above 80 or 90 while resting, your heart is working harder than it probably needs to.
Age plays a role too. Kids have much faster heart rates because their bodies are smaller and growing rapidly. A newborn might have a pulse of 130 bpm, which would be a medical emergency for an adult but is totally fine for a baby. As we get older, the heart rate generally stabilizes, though it can become more irregular as the electrical system of the heart wears down over decades.
Factors That Mess With Your Numbers
A lot of things can spike your pulse temporarily. Stress is a big one. When you're anxious, your adrenal glands pump out cortisol and adrenaline, which tell your heart to pick up the pace for a "fight or flight" response. Even if you're just sitting in traffic, your body thinks you might need to outrun a predator.

Caffeine is another culprit. That double espresso isn't just waking up your brain; it’s a stimulant that directly affects your heart’s sinoatrial node. Dehydration is a sneaky one too. When you’re low on fluids, your blood volume drops, making it "thicker" and harder to pump, so the heart beats faster to compensate.
- Medications: Beta-blockers can slow it down; some asthma inhalers can speed it up.
- Temperature: High heat and humidity make the heart work harder to cool you off.
- Emotions: Surprise, fear, or even intense joy can cause a sudden jump.
Understanding Your Pulse During Exercise
When you start moving, the answer to what’s your pulse supposed to be changes completely. This is where we talk about "Target Heart Rate."
The old-school way to find your maximum heart rate is 220 minus your age. So, if you're 40, your estimated max is 180 bpm. Honestly, this formula is a bit outdated and doesn't account for individual fitness levels, but it’s a decent starting point. During moderate-intensity exercise, you generally want to be at 50% to 70% of that maximum. For a 40-year-old, that’s roughly 90 to 126 bpm.
If you’re really pushing it—what experts call vigorous activity—you might hit 70% to 85% of your max.
Monitoring this is easier than ever with smartwatches, but don't obsess over the screen. If you can talk but not sing, you’re likely in the moderate zone. If you can only gasp out a word or two, you’re in the vigorous zone. It’s that simple. You don't need a $500 watch to tell you your heart is pounding after a sprint.
The Importance of Recovery Heart Rate
One of the best markers of a "young" heart isn't how high it goes, but how fast it comes back down. This is your recovery heart rate.

If you stop exercising and your pulse drops by 15 to 20 beats in the first minute, that’s a fantastic sign of cardiovascular health. It means your nervous system is responsive and can quickly switch from "go mode" to "rest mode." If your pulse stays high for a long time after you've stopped moving, it might be a sign that you need to work on your aerobic base or talk to a doctor about your heart's efficiency.
When Should You Actually Worry?
We’ve established that "normal" is a wide net. But there are definitely red flags. Tachycardia is the medical term for a resting heart rate over 100 bpm. Bradycardia is when it's under 60 bpm (unless you're a high-level athlete).
If your pulse is high and you’re also feeling dizzy, short of breath, or having chest pains, that’s not just "stress." That’s a reason to seek medical attention. Conditions like atrial fibrillation (Afib) can cause your pulse to feel irregular, like a "flopping fish" in your chest. Afib increases the risk of stroke, so it's not something to ignore.
Also, look for consistency. If your resting pulse is usually 65 and suddenly it’s 85 for three days straight without any change in your caffeine intake or exercise, your body might be fighting off an infection. Many people see their heart rate rise on their fitness trackers a day or two before they actually feel sick with the flu or COVID-19.
How To Check It Properly
Don't check your pulse right after a cup of coffee or a stressful meeting.
- Sit quietly for at least five minutes. No phone, no TV.
- Use your index and middle fingers—not your thumb, because your thumb has its own pulse.
- Place them on your wrist (radial pulse) or the side of your neck (carotid pulse).
- Count the beats for 30 seconds and multiply by two. Or 60 seconds for the most accuracy.
Do this a few mornings in a row right after you wake up. This will give you your true baseline. Once you know your baseline, you’ll be much better at spotting when something is off.

Actionable Steps for Heart Health
If you find that your pulse isn't where you want it to be, you aren't stuck with it. The heart is a muscle, and like any muscle, it can be trained.
Increase your cardiovascular activity. Aim for at least 150 minutes of moderate aerobic activity per week. This strengthens the heart walls and increases the volume of blood pumped per beat. Over time, this naturally lowers your resting pulse.
Watch the stimulants. If you're sensitive to caffeine, try cutting back or stopping by noon. You might find your "anxious" heart rate is actually just a "caffeinated" heart rate.
Prioritize magnesium and potassium. These minerals are electrolytes that help regulate the electrical signals in your heart. Leafy greens, bananas, and nuts are your friends here.
Manage your sleep. Sleep deprivation keeps your sympathetic nervous system (the "alert" system) active, which keeps your heart rate elevated even when you think you're resting. Most people need 7 to 9 hours for their heart to truly recover.
Practice deep breathing. Techniques like box breathing—inhale for 4, hold for 4, exhale for 4, hold for 4—can almost instantly lower your heart rate by stimulating the vagus nerve. It’s a physical "hack" for your nervous system.
Focus on the trends rather than a single measurement. Your heart rate is a dynamic, living number that responds to your environment, your health, and your emotions. Understanding your personal "normal" is the first step toward long-term cardiovascular wellness. Check your resting rate tomorrow morning before you get out of bed to find your true starting point.
