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 a sustainable workout intensity.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ THR_{zone} = (220 - age) \times 0.6 \text{ to } 0.7 \]

Where:

220 - age — Estimated maximum heart rate
0.6 to 0.7 — Percentage range for fat burning zone

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

3. Importance of Fat Burning Zone

Details: Exercising in this zone maximizes the percentage of calories burned from fat while maintaining an intensity that can be sustained for longer periods.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Is this formula accurate for everyone?
A: This is an estimation. Individual maximum heart rates can vary by ±10-20 bpm due to fitness level and genetics.

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

Q3: Can I burn fat in higher heart rate zones?
A: Yes, but higher zones burn more carbohydrates as a percentage, though total calories burned will be higher.

Q4: Should I use this if I'm on heart medications?
A: Consult your doctor first, as some medications affect heart rate response.

Q5: Are there more accurate methods?
A: A graded exercise test with gas analysis provides the most accurate fat burning zone measurement.
