1. What is Target Heart Rate Zone?

The Target Heart Rate (THR) zone is the optimal heart rate range for cardiovascular training. Exercising within this zone improves cardiovascular fitness while maintaining safety.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The formula provides a safe and effective heart rate range for moderate-intensity cardiovascular exercise.

3. Importance of Target Heart Rate

Details: Training 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 recommended heart rate range for cardio training.

5. Frequently Asked Questions (FAQ)

Q1: Why use 220-age for max heart rate?
A: It's a widely accepted estimate, though individual variations exist. For more accuracy, consider a stress test.

Q2: What if my heart rate goes above the upper limit?
A: You may be working too hard. Slow down to stay within your target zone for safer, more effective training.

Q3: Are there different zones for different goals?
A: Yes, 60-80% is for general cardio. Higher zones (up to 85-90%) are for advanced interval training.

Q4: How accurate is this calculation?
A: It provides a good estimate for most people, but individual factors like fitness level and medications can affect actual heart rate.

Q5: Should I check my heart rate during exercise?
A: Yes, especially when starting. Use a heart rate monitor or check your pulse periodically to stay in your target zone.
