1. What is Maximum Heart Rate?

Maximum Heart Rate (MHR) is the highest number of beats per minute your heart can achieve during maximum physical exertion. The most common formula for estimating MHR is 220 minus your age.

2. How Does the Calculator Work?

The calculator uses the standard maximum heart rate equation:

Where:

• \( \text{Age} \) — Your current age in years (must be 18 or older)

Explanation: This formula provides a simple estimate of your maximum safe heart rate based on age.

3. Importance of Heart Rate Calculation

Details: Knowing your maximum heart rate helps determine appropriate exercise intensity levels and target heart rate zones for different training purposes.

4. Using the Calculator

Tips: Simply enter your age (must be 18 years or older). The calculator will estimate your maximum heart rate.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is the 220-age formula?
A: It's a general estimate - individual maximum heart rates can vary by ±10-20 beats per minute.

Q2: Are there alternative formulas?
A: Yes, some suggest 208 - (0.7 × age) may be more accurate, especially for older adults.

Q3: What are typical heart rate zones?
A: Moderate exercise is typically 50-70% of max HR, vigorous is 70-85% of max HR.

Q4: Should everyone use the same formula?
A: Athletes and highly fit individuals may have different max HR values than predicted.

Q5: When is this formula not appropriate?
A: Not recommended for children, or individuals with certain heart conditions or on medications affecting heart rate.
