1. What is Target Heart Rate Zone?

The target heart rate zone is the range of heartbeats per minute that you should aim for during exercise to get cardiovascular benefits. It's typically expressed as a percentage of your maximum heart rate.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Max\ HR \) — Maximum heart rate in beats per minute (bpm)
• \( Intensity \) — Desired exercise intensity as a percentage (e.g., 60% for moderate exercise)

Explanation: The calculation determines the heart rate you should maintain to exercise at a specific intensity level.

3. Importance of Heart Rate Zones

Details: Training in specific heart rate zones can help optimize workouts for different goals like fat burning, endurance, or performance improvement.

4. Using the Calculator

Tips: Enter your maximum heart rate (or estimated as 220 minus your age) and the desired intensity percentage. All values must be valid (HR > 0, intensity between 0-100).

5. Frequently Asked Questions (FAQ)

Q1: How do I determine my maximum heart rate?
A: The most common estimation is 220 minus your age, but a stress test provides the most accurate measurement.

Q2: What are typical intensity zones?
A: Moderate intensity is 50-70% of max HR, vigorous is 70-85%. Exact zones vary by fitness level and goals.

Q3: Should everyone use the same zones?
A: No, optimal zones vary based on fitness level, age, and health conditions. Consult a professional for personalized advice.

Q4: How accurate is the 220-age formula?
A: It's a rough estimate. Actual max HR can vary by ±10-20 bpm from this prediction.

Q5: Can I exceed my target zone?
A: While brief periods above your zone are normal during interval training, sustained high intensity may be unsafe for some individuals.
