1. What is Target Heart Rate Zone?

The target heart rate zone for fat burning is typically 60-70% of your maximum heart rate. Exercising in this zone helps optimize fat burning while maintaining moderate intensity.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• 220 — Estimated maximum heart rate constant
• age — Your current age in years
• 0.6 to 0.7 — Percentage range for fat burning zone

Explanation: The formula first estimates your maximum heart rate (220 - age), then calculates 60-70% of that value to determine your optimal fat burning zone.

3. Importance of Fat Burning Zone

Details: Exercising in this zone helps your body use fat as its primary fuel source. It's ideal for weight management and improving cardiovascular health without excessive strain.

4. Using the Calculator

Tips: Simply enter your age in years. The calculator will show your target heart rate range for optimal fat burning during exercise.

5. Frequently Asked Questions (FAQ)

Q1: Is this formula accurate for everyone?
A: While the 220-age formula is widely used, individual maximum heart rates can vary by ±10-20 bpm. For more accuracy, consider a stress test.

Q2: How long should I stay in this zone?
A: For fat burning, aim for 30-60 minutes of continuous exercise in this zone, 3-5 times per week.

Q3: Can I burn fat at higher heart rates?
A: Yes, but at higher intensities your body uses more carbohydrates as fuel. The fat burning zone offers the highest percentage of calories from fat.

Q4: Does this work for all ages?
A: The formula works reasonably well for most adults, but may be less accurate for very young or elderly individuals.

Q5: How can I measure my heart rate during exercise?
A: Use a heart rate monitor, fitness tracker, or manually check your pulse for 15 seconds and multiply by 4.
