1. What is Target Heart Rate Zone?

The Target Heart Rate (THR) zone for fat burning is the optimal heart rate range during exercise where your body burns the highest percentage of calories from fat. 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 - age — Estimated maximum heart rate
• 0.6 to 0.7 — Percentage range for fat burning zone

Explanation: The formula first estimates your maximum heart rate based on age, then calculates the 60-70% range which is optimal for fat burning.

3. Importance of Target Heart Rate

Details: Exercising within your target heart rate zone ensures you're working at the right intensity to maximize fat burning while maintaining cardiovascular benefits.

4. Using the Calculator

Tips: Enter your age in years. The value must be valid (between 1-120). The calculator will show your optimal heart rate range for fat burning exercise.

5. Frequently Asked Questions (FAQ)

Q1: Is the 220-age formula accurate for everyone?
A: While commonly used, it's an estimate. 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 optimal fat burning, aim for 30-60 minutes in this zone, 3-5 times per week.

Q3: Can I burn fat at higher intensities?
A: Yes, but the percentage of calories from fat decreases as intensity increases, though total calorie burn is higher.

Q4: What are signs I'm in the right zone?
A: You should be able to talk in short sentences but feel moderately exerted. Consider using a heart rate monitor for accuracy.

Q5: Does this apply to all ages?
A: The formula works for adults. Children and elite athletes may need specialized calculations.
