1. What is Max Heart Rate?

Max Heart Rate (MHR) is the highest number of beats per minute your heart can achieve during maximal physical exertion. The most common formula to estimate MHR is 220 minus your age.

2. How Does the Calculator Work?

The calculator uses the standard Max Heart Rate equation:

Where:

• \( age \) — Age in years

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

3. Importance of MHR Calculation

Details: Knowing your estimated maximum heart rate helps in designing safe and effective exercise programs by establishing appropriate heart rate training zones.

4. Using the Calculator

Tips: Simply enter your age in years. The value must be between 1-120 years.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is the 220-age formula?
A: It's a general estimate with standard deviation of about 10-12 bpm. Individual variations exist based on fitness level and genetics.

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

Q3: How is MHR used in exercise?
A: Training zones are typically calculated as percentages of your MHR (e.g., 50-70% for fat burning, 70-85% for cardio).

Q4: Can you exceed your MHR?
A: It's physiologically difficult and potentially dangerous to sustain exercise at or above your true maximum heart rate.

Q5: Does fitness level affect MHR?
A: Surprisingly, no. MHR is largely age-dependent, though fitness affects how long you can sustain high percentages of MHR.
