1. What is Target Heart Rate?

Target Heart Rate is the desired heart rate range you should aim for during exercise to get cardiovascular benefits. It's typically expressed as a percentage (usually 50-85%) of your maximum heart rate.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• 220 — Estimated maximum heart rate for adults
• Age — Your current age in years
• Intensity — The percentage of maximum heart rate you want to target (typically 50-85%)

Explanation: The formula first estimates your maximum heart rate by subtracting your age from 220, then calculates the target zone by applying the intensity percentage.

3. Importance of Target Heart Rate

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

4. Using the Calculator

Tips: Enter your age in years and desired intensity percentage (50-85%). For moderate exercise, use 50-70%. For vigorous exercise, use 70-85%.

5. Frequently Asked Questions (FAQ)

Q1: Why use 220 - age for maximum heart rate?
A: This is a widely accepted estimate, though individual maximum heart rates can vary by ±10-20 bpm.

Q2: What are common target heart rate zones?
A: Moderate intensity: 50-70% of max HR. Vigorous intensity: 70-85% of max HR.

Q3: Are there more accurate formulas?
A: The Tanaka formula (208 - 0.7 × age) may be slightly more accurate for older adults.

Q4: Who shouldn't use this calculation?
A: People on certain medications (like beta blockers) or with heart conditions should consult a doctor.

Q5: How can I measure my heart rate during exercise?
A: Use a heart rate monitor or count your pulse for 15 seconds and multiply by 4.
