1. What is the Fat Burning Zone?

The fat burning zone refers to the heart rate range where your body burns the highest percentage of calories from fat during exercise. For women, this is typically between 60-70% of your maximum heart rate.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( \text{MHR} \) — Maximum Heart Rate (220 - age)
• \( 0.6 \) — Lower bound percentage (60%)
• \( 0.7 \) — Upper bound percentage (70%)

Explanation: This range optimizes fat metabolism while maintaining moderate exercise intensity suitable for most women.

3. Importance of Fat Burning Zone

Details: Training in this zone helps improve metabolic efficiency, promotes fat loss while preserving muscle, and is sustainable for longer durations.

4. Using the Calculator

Tips: Enter your age and resting heart rate for the most accurate calculation. The results show your personalized fat burning heart rate range.

5. Frequently Asked Questions (FAQ)

Q1: Is the fat burning zone different for women?
A: While the percentage range is similar, women often have higher resting heart rates, making their actual zone numbers slightly higher than men of the same age.

Q2: How accurate is the 220-age formula?
A: It's a general estimate. For greater accuracy, consider a maximal exercise test under medical supervision.

Q3: Should I only exercise in this zone?
A: No. While good for fat metabolism, include higher intensity intervals for cardiovascular benefits and strength training for muscle maintenance.

Q4: How do I measure my heart rate during exercise?
A: Use a heart rate monitor or check your pulse at your wrist for 15 seconds and multiply by 4.

Q5: Does this work for weight loss?
A: Yes, but total calorie expenditure matters most. This zone helps optimize fat utilization during the workout itself.
