Ever wonder if your workout is actually working? Your heart has the answer. Every time you exercise, it beats faster to keep up with you. Your target heart rate is the safe, sweet spot where your heart works hard enough to help you, but not so hard that it hurts you.
Finding your number is easy. All you need is your age and one simple formula. Once you know your zone, you can train smarter and keep your heart happy. Ready to find your exact number?
What Is Target Heart Rate?
A target heart rate is the rate at which your heart beats during exercise. It’s between your resting heart rate and your maximum heart rate. Most adults have a normal heart rate of between 60 and 100 beats per minute.
Now, stay in this zone, and your heart becomes stronger with every workout. Drift too low, and you barely feel it. Push too high, and you could overdo it.
What Is a Resting Heart Rate?
This one’s just your pulse when you’re doing absolutely nothing. Lying on the couch, watching TV, whatever. For most people that lands between 60 and 100 beats per minute (bpm). Runners and cyclists often sit way lower, some even dip to 40 or 50 bpm after years of training.
Does Resting Heart Rate Change With Age?
Your age, of course, influences your resting pulse, and that number goes directly into your maximum heart rate formula which you use to figure out your zone, so it matters.
It does change, yes. Kids’ hearts naturally beat faster than adults’ hearts. Bonus: As you become fitter, your resting rate tends to decrease.
Step 1: Find Your Maximum Heart Rate
Here’s the easy math. Take 220 and subtract your age. That’s it. Say you’re 30 years old, your maximum heart rate lands around 190 bpm. This one number sets the top of your whole heart rate zone.
Step 2: Calculate Your Target Heart Rate Zone
Next, multiply this MHR number by 50 percent and then by 85 percent. The two results are your target heart rate zone. For us 30 year olds, that’s around 95-162 bpm.
What Do the Different Heart Rate Zones Mean?
Not every zone is equal and each will tax your body in a different way; understanding the zones will help you choose the appropriate zone for your goal.
- Light zone:60-70% of MHR, moderate warm ups
- Fat-burning zone: 60 to 70 percent of MHR – steady cardio
- Aerobic zone:70 – 80% of MHR, good heart health benefits
- Tough interval training: 80 to 90% of MHR in the anaerobic zone
- Max effort zone: 90-100% of MHR – short sprints only
Step 3: Don’t Forget Your Own Body
A few things can throw off the standard formula. Certain medicines, pregnancy, and some health conditions all change how your heart responds. If you take heart medication, check with your doctor first. Your fitness level matters too.
Target Heart Rate Chart by Age
| Age | Target Zone (50-85%) | Max Heart Rate |
| 20 | 100-170 bpm | 200 bpm |
| 30 | 95-162 bpm | 190 bpm |
| 40 | 90-153 bpm | 180 bpm |
| 50 | 85-145 bpm | 170 bpm |
| 60 | 80-136 bpm | 160 bpm |
How to Find Your Pulse Without a Gadget
No fancy device? No problem. Press two fingers on your wrist or the side of your neck. Count the beats for 30 seconds, then double that number. You’ve got your beats per minute.
Track Your Full Fitness Picture
Your heart rate is just one piece of the puzzle though. Curious how many calories your body burns doing nothing? Try the BMR Calculator. Want to plan your food around your daily activity? The TDEE Calculator has you covered.
Pair your Body Fat Calculator result with your heart rate zone. Together, they paint a much fuller picture of how you’re really doing.
Listen to Your Body Too
Numbers help, but your body talks too, so listen to it. Feeling dizzy, short of breath, or getting chest pain? Stop right away, no exceptions. Pulse racing past your zone? Ease off a little. Barely breaking a sweat? Push yourself a bit harder.
Frequently Asked Questions
What is the best range of exercise heart rates?
A target heart rate is the best range to target and is 50-85 percent of the maximum heart rate. This will depend on your age and fitness, and will continuously get better as your heart gets stronger.
How do I calculate my maximum heart rate?
Just subtract your age from 220. That gives you a solid starting estimate, though your real number can vary a bit based on genetics, fitness, and your general health picture.
Why is target heart rate important?
It helps you exercise at just the right intensity to see real results. You stay safe, yet still push your heart enough to build lasting cardiovascular fitness over time.
Can medication affect my heart rate?
Yes, medicines like beta blockers can lower your maximum heart rate quite a bit. Talk to your doctor about your true target zone if you take any heart related medication
