1. What is Heart Rate Zone?

Heart Rate Zones are ranges that indicate different intensity levels of exercise based on your maximum heart rate. They help optimize training by targeting specific physiological benefits.

2. How Does the Calculator Work?

The calculator uses the basic HR Zone equation:

Where:

• \( age \) — Age in years
• \( intensity \) — Percentage of maximum heart rate (as decimal)

Explanation: The equation estimates maximum heart rate (220 - age) and then calculates the target heart rate for a given intensity percentage.

3. Importance of HR Zone Calculation

Details: Training in specific heart rate zones can help improve cardiovascular fitness, burn fat more efficiently, and track exercise intensity for optimal results.

4. Using the Calculator

Tips: Enter your age in years and the desired intensity percentage (typically 50-85% for training zones). All values must be valid (age between 1-120, intensity between 0-100).

5. Frequently Asked Questions (FAQ)

Q1: Why use 220-age for max HR?
A: This is a simple estimation formula. While not perfect for everyone, it provides a reasonable estimate for most people.

Q2: What are typical HR zones?
A: Common zones are: Zone 1 (50-60% for warm-up), Zone 2 (60-70% for fat burning), Zone 3 (70-80% for aerobic), Zone 4 (80-90% for anaerobic), Zone 5 (90-100% for max effort.

Q3: When should I measure my HR during exercise?
A: For most accurate readings, measure after at least 5 minutes of continuous exercise when your heart rate has stabilized.

Q4: Are there limitations to this calculation?
A: Individual variations exist due to fitness level, genetics, medications, and other factors. For precise training, consider a professional assessment.

Q5: Should I use this for all types of exercise?
A: This works best for steady-state cardio. High-intensity interval training (HIIT) may require different monitoring approaches.
