1. What Is the Fat Burning Zone?

The fat burning zone refers to a heart rate range where your body burns a higher percentage of calories from fat during exercise. For men, this is typically 60-70% of your maximum heart rate (MHR).

2. How Does the Calculator Work?

The calculator uses the fat burning zone formula:

Where:

• \( \text{MHR} \) — Maximum Heart Rate in beats per minute (bpm)
• \( 0.6 \) — Lower limit coefficient (60% of MHR)
• \( 0.7 \) — Upper limit coefficient (70% of MHR)

Explanation: This range represents the optimal heart rate for maximizing fat burn during exercise.

3. Importance of Fat Burning Zone

Details: Training in this zone helps improve fat metabolism and is ideal for weight management and endurance training.

4. Using the Calculator

Tips: Enter your maximum heart rate (MHR) in bpm. If you don't know your MHR, you can estimate it by subtracting your age from 220 (for men).

5. Frequently Asked Questions (FAQ)

Q1: Is the fat burning zone the same for everyone?
A: While the percentage range is similar, the actual heart rate values will vary based on individual maximum heart rates.

Q2: Can I burn fat outside this zone?
A: Yes, you burn fat at all intensities, but the percentage of calories from fat is highest in this zone.

Q3: How accurate is the 220-age formula for MHR?
A: It's a general estimate - individual variations can be ±10-20 bpm. A stress test provides the most accurate measurement.

Q4: Should I only exercise in the fat burning zone?
A: For optimal fitness, include a variety of intensities in your training program.

Q5: Does this apply to both cardio and strength training?
A: Primarily for cardio - strength training typically doesn't elevate heart rate into this zone for sustained periods.
