Target Heart Rate Calculator
❤️ Target Heart Rate Calculator | Train Smarter, Not Harder
Understanding your target heart rate can make a huge difference in how effectively you exercise. Whether you're trying to burn fat, improve cardiovascular fitness, or optimize endurance, knowing the heart rate range that works best for your body helps you train with purpose.
The Target Heart Rate Calculator from GoodTechReview is a simple, free tool that helps you determine the ideal heart rate zone for your fitness goals. Based on your age and optionally your resting heart rate, our calculator gives you personalized ranges that align with how your body responds to exertion.
💡 What Is Target Heart Rate?
Target heart rate (THR) is the range of beats per minute (BPM) your heart should reach during physical activity to achieve specific training benefits. It represents a percentage of your maximum heart rate (MHR), typically ranging from 50% to 85%, depending on your goal.
- 50–60% MHR – Light intensity (warm-up, recovery)
- 60–70% MHR – Fat burning
- 70–80% MHR – Aerobic conditioning
- 80–90% MHR – Anaerobic threshold training
- 90–100% MHR – Maximum effort, high-intensity intervals
By training in the right zone, you avoid undertraining or overtraining and maximize each workout session.
🧮 How the Target Heart Rate Calculator Works
The GoodTechReview Target Heart Rate Calculator uses basic health data, primarily your age, to estimate your maximum heart rate using the standard formula:
MHR = 220 − your age
Then, it calculates your training zones by applying percentages of your MHR, giving you a complete picture of where your heart rate should fall during different types of exercises.
Optionally, if you know your resting heart rate (RHR), the calculator can use the Karvonen Formula, which offers more personalized results:
THR = [(MHR − RHR) × %Intensity] + RHR
This method is especially helpful for athletes or anyone with higher or lower resting heart rates than average.
🧠 Why Knowing Your Target Heart Rate Matters
1. Smarter workouts:
Instead of guessing, you train at the exact intensity your body needs.
2. Fat loss efficiency:
Staying in the fat-burning zone helps optimize weight loss goals.
3. Cardiovascular health:
Aerobic zones improve heart health and stamina over time.
4. Recovery and safety:
Avoiding overexertion reduces injury risk and keeps your body balanced.
5. Performance tracking:
Monitoring heart rate allows you to see progress and adjust your training plan accordingly.

❓ 5 Frequently Asked Questions (FAQs)
1. What is the best target heart rate for fat burning?
The ideal fat-burning zone is usually 60–70% of your maximum heart rate. It promotes efficient fat usage during cardio workouts.
2. Is it safe to train at 90–100% heart rate?
Only for short intervals and if you're healthy. This zone is used for HIIT or athletic conditioning and should be monitored closely.
3. How can I measure my heart rate during exercise?
Use a fitness tracker, chest strap, or simply check your pulse manually during rest periods.
4. Is resting heart rate important?
Yes. A lower resting heart rate often indicates better cardiovascular fitness. It's also used in more precise calculations like the Karvonen Formula.
5. How often should I recalculate my target heart rate?
Recheck it if your fitness level improves, your age changes, or you’ve started a new workout program.
