1. What is the Fat Burning Zone?

The fat burning zone refers to a heart rate range where your body is believed to burn a higher percentage of calories from fat during exercise. This zone is typically 60-70% of your maximum heart rate.

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 — Lower limit multiplier (60% of max HR)
• 0.7 — Upper limit multiplier (70% of max HR)

Explanation: The formula estimates your maximum heart rate based on age, then calculates the target range for optimal fat burning.

3. Importance of Fat Burning Zone

Details: Exercising in this zone may help maximize fat utilization, though higher intensity workouts may burn more total calories overall.

4. Using the Calculator

Tips: Enter your age in years (must be between 1-120). The calculator will show your estimated fat burning heart rate zone.

5. Frequently Asked Questions (FAQ)

Q1: Is the 220-age formula accurate for everyone?
A: It's a general estimate. Individual maximum heart rates can vary by ±10-20 beats.

Q2: Should I only exercise in this zone?
A: No, variety is important. Higher intensities improve cardiovascular fitness and burn more total calories.

Q3: How do I measure my heart rate during exercise?
A: Use a heart rate monitor or manually check your pulse for 15 seconds and multiply by 4.

Q4: Does this zone guarantee fat loss?
A: Fat loss depends on overall calorie balance. This zone may optimize fat utilization during exercise.

Q5: Are there better formulas for athletes?
A: Yes, trained individuals might use 208 - (0.7 × age) for more accurate max HR estimation.
