Calculate your target heart rate zone for optimal workouts. Enter your age (and optional resting heart rate) to see BPM targets and get tips on training intensity.
What’s the Sweet Spot for Your Heartbeat? Let’s Find Out!
Sure, you can smash a workout and hope your heart was doing its job. But wouldn’t it be better to know the exact BPM range you should aim for? Welcome to the Target Heart Rate Calculator, your personal exercise intensity radar.
Why Target Heart Rate Matters
Exercise intensity isn’t “go hard or go home” (though sometimes it feels like it). Too soft, and your workout barely registers. Too hard, and you might burn out or risk injury. The “sweet zone” is in between, where you get cardio benefits without overdoing it. Knowing your target heart rate zone helps you dial in that balance.
Medical and fitness guidelines set moderate intensity at roughly 50% to 85% of your maximum heart rate. Some advanced tools even adjust for your resting heart rate (the Karvonen method / Heart Rate Reserve) to make it personalized.
How This Tool Works
Enter your age, and optionally your resting heart rate (bpm) if you know it.
Choose an intensity level (50%, 60%, 70%, etc.). Click Calculate to see your target range, a lower and upper bound in bpm. If you provided a resting heart rate, it uses the Karvonen (HR Reserve) method. Otherwise, it uses the simpler percentage-of-max-HR method.
Want to keep it handy? Copy it, WhatsApp it, or email it to yourself. You’ll also see an estimated maximum heart rate (220 minus age) a rough ceiling many fitness tools use.

Why Use This Zone Info
- It helps you pace workouts: stay in zone rather than going rogue
- It’s a smart guide for cardio sessions, HIIT, and endurance training
- It gives you feedback mid-session: “Am I pushing too hard? Too easy?”
- Over time, you might refine (or override) it based on your fitness, results, or health conditions
One caveat, medicines, fitness level, heart conditions, etc. can affect your actual heart rate limits. Always use this as a guide and consult your doctor if in doubt.
Final Word - Let Your Heart Lead the Way - But Don’t Freak It Out
Go ahead, punch in your age, pick an intensity, see where your heart should be working. Use that zone as your heart’s training playlist: push when it’s on beat, ease off when you’re off tempo.
If you liked this tool, pass it on to someone who still judges workouts by “how sweaty I got.” Tell us if the numbers lined up or if the range felt off, feedback is fuel. And if you want more calculators (VO₂ Max, lactate threshold, you name it), I’m ready to build them next.
