You're sitting on the couch, maybe after a long day or right after a double espresso, and you feel that familiar thumping in your neck. You check your smartwatch. It says 78. Or maybe 54. Suddenly, you’re spiraling down a Google rabbit hole. What is a good pulse, anyway? Honestly, the answer isn't a single number that applies to every human on the planet. It’s a moving target. Your heart is an adaptable muscle, and what’s "normal" for a marathon runner would likely send a sedentary office worker to the ER.
Most doctors will tell you that a standard resting heart rate (RHR) for an adult falls between 60 and 100 beats per minute (bpm). But that’s a massive range. It's like saying a "normal" price for a car is anywhere between $5,000 and $95,000. While technically true, it doesn't tell the whole story. If your pulse is consistently sitting at 95 while you’re just watching Netflix, you might be "within range," but you’re certainly not at peak cardiovascular health.
The Nuance of the Resting Rate
Your resting heart rate is basically a snapshot of how efficiently your heart is working. When you're fit, your heart muscle is stronger. It pumps more blood with every single squeeze. Because it’s so efficient, it doesn't need to beat as often. This is why elite athletes, like Olympic cross-country skiers or cyclists, often have resting pulses in the 30s or 40s.
For the rest of us? Aiming for something in the 50s or 60s is usually a sign of solid aerobic conditioning.
But things get weird. Age matters. A lot. Newborns have pulses that would look like a hummingbird's to an adult—100 to 150 bpm is totally standard for a baby. As we grow, that rate slows down. By the time you’re a teenager, you’ve settled into that adult range. Then there's the gender gap. Generally speaking, women tend to have slightly higher resting heart rates than men, partly because women’s hearts are typically smaller and need to beat a bit faster to move the same volume of blood.
What Is a Good Pulse When You're Actually Moving?
Moving changes everything. Once you stand up, head to the gym, or even just get into a heated argument about who forgot to take out the trash, your pulse climbs. This is where we talk about target heart rate zones.

To figure out if you have a "good" pulse during exercise, you first need to know your maximum heart rate. The old-school formula is simple: subtract your age from 220. If you’re 40, your estimated max is 180.
- Moderate intensity: 50% to 70% of your max.
- Vigorous intensity: 70% to 85% of your max.
If you’re 40 years old and doing a brisk walk, a "good" pulse would be somewhere between 90 and 126 bpm. If you’re sprinting? You’re looking at 126 to 153 bpm.
Why Your "Good" Number Might Change Daily
Your pulse is a snitch. It tells on you when you’ve had too much caffeine, when you’re dehydrated, or when you’re coming down with a cold. Have you ever noticed your heart racing after a big night out? That’s because alcohol is a vasodilator and a stressor; your heart has to work harder to maintain blood pressure and process toxins.
Stress is the other big one. High cortisol levels keep your heart on high alert. If you’re chronically stressed, your "resting" heart rate might stay elevated for weeks. It’s not just about physical fitness; it’s about your nervous system's "tone."
Medications are a massive factor too. Beta-blockers, often prescribed for high blood pressure, will artificially lower your pulse. You could be working out at a level that feels like an 8 out of 10, but your pulse might only show 110 bpm. On the flip side, some asthma inhalers or decongestants can send your pulse soaring.

When a "Good" Pulse Goes Bad: Tachycardia and Bradycardia
Sometimes the numbers go outside the lines. If your resting heart rate is consistently above 100, that’s called tachycardia. If it’s under 60, it’s bradycardia.
Now, don't panic. If you’re a distance runner and your pulse is 48, you’re fine. That’s "athletic bradycardia." But if you’re not an athlete and your pulse is 48, and you feel dizzy, tired, or like you’re about to faint? That’s a problem. It means your brain isn't getting enough oxygenated blood.
Tachycardia is often more noticeable. You might feel "palpitations," which is just a fancy way of saying you can feel your heart thumping or skipping a beat. According to the American Heart Association, while a high pulse can be caused by something as simple as a fever or anemia, it can also point to underlying electrical issues in the heart, like Atrial Fibrillation (AFib).
The Hidden Metric: Heart Rate Variability (HRV)
If you really want to be an overachiever in understanding what is a good pulse, you have to look at Heart Rate Variability.
HRV isn't the number of beats per minute. It’s the variation in time between each beat. Surprisingly, you don't want a heart that beats like a perfect metronome. You want a heart that is slightly "irregular" in its timing. High HRV means your autonomic nervous system is balanced and can switch easily between "fight or flight" and "rest and digest." If your heart rate is 60 bpm but the timing between beats is exactly 1.00 seconds every time, you're likely overtrained or incredibly stressed.

How to Get a "Better" Pulse
If you’ve checked your numbers and decided you aren't happy with your resting rate, there’s good news: the heart is incredibly plastic. You can train it.
- Cardio, obviously. You don't need to run marathons. Even 30 minutes of zone 2 training (where you can still hold a conversation) three times a week will strengthen the heart muscle and lower your RHR over time.
- Hydration is king. When you're dehydrated, your blood volume drops. Thinner volume means the heart has to beat faster to move what's left. Drink your water.
- Magnesium and Potassium. These electrolytes are the "spark plugs" for your heart's electrical system. A deficiency can lead to an erratic or high pulse.
- Sleep. During deep sleep, your heart rate should reach its absolute lowest point. If you aren't sleeping well, your heart never gets that recovery window.
Real-World Testing
To get an accurate reading of your resting pulse, don't check it right after you’ve climbed the stairs or while you’re worrying about a work deadline. The best time is the very second you wake up, before you even get out of bed. Put two fingers on your wrist (the radial artery) or your neck (the carotid artery). Count the beats for 30 seconds and multiply by two.
Do this for three days in a row and take the average. That is your true baseline.
If that average is consistently high (over 90-100) or if you’re seeing weird drops accompanied by lightheadedness, go talk to a professional. A simple EKG can rule out the scary stuff.
Actionable Steps for Heart Health
Understanding your pulse is about more than just data—it's about listening to the body's internal rhythm.
- Establish your baseline: Use the three-day morning check mentioned above. Write it down.
- Audit your lifestyle: If your pulse is high, look at your caffeine intake, sleep quality, and stress levels over the last 48 hours before worrying about heart disease.
- Incorporate "Zone 2" exercise: Focus on activity where your heart rate is roughly 60-70% of your max. This builds the "aerobic base" that lower resting rates are built on.
- Watch for trends, not outliers: One high reading doesn't mean anything. A trend of rising resting heart rates over a month is a signal to slow down and recover.
- Consult the experts: If your pulse feels irregular (skipping beats) or is consistently outside the 60-100 range without athletic training, schedule an appointment with a primary care physician or a cardiologist.
Your heart is the only engine you get. It's worth paying attention to the dashboard every once in a while.
