1. What is Target Heart Rate Zone?

The Target Heart Rate (THR) zone is the ideal range of heart rate you should aim for during cardio exercise to maximize cardiovascular benefits. For moderate-intensity exercise, this is typically 60-80% of your maximum heart rate.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• 220 - age — Estimated maximum heart rate (beats per minute)
• 0.6 — Lower bound of target zone (60% of max HR)
• 0.8 — Upper bound of target zone (80% of max HR)

Explanation: The equation estimates your maximum heart rate based on age, then calculates the ideal range for moderate-intensity cardiovascular exercise.

3. Importance of Heart Rate Zones

Details: Exercising within your target heart rate zone ensures you're working at the right intensity to improve cardiovascular fitness without overexertion.

4. Using the Calculator

Tips: Enter your age in years. The calculator will show your ideal heart rate range for moderate cardio exercise. Always consult a doctor before starting new exercise programs.

5. Frequently Asked Questions (FAQ)

Q1: Is the 220-age formula accurate for everyone?
A: It's a general estimate. Individual maximum heart rates can vary by ±10-20 bpm. More accurate methods include stress tests.

Q2: What if I'm very fit or a competitive athlete?
A: Athletes may have different target zones. Consider consulting with a sports medicine specialist for personalized guidance.

Q3: Are there other heart rate zones?
A: Yes, typically five zones from very light (50-60%) to maximum effort (90-100%). This calculator shows the moderate-intensity zone.

Q4: How should I measure my heart rate during exercise?
A: Use a heart rate monitor for best accuracy, or take your pulse for 15 seconds and multiply by 4.

Q5: When should I adjust my target zone?
A: Recalculate annually as your maximum heart rate decreases with age, or if your fitness level changes significantly.
