1. What Are Heart Rate Zones?

Heart rate zones are specific ranges of heartbeats per minute that correspond to different levels of exercise intensity. They help optimize training by targeting specific physiological adaptations.

2. How Does the Calculator Work?

The calculator uses the heart rate zone formula:

Where:

• \( MHR \) — Maximum Heart Rate (bpm)
• \( \% Intensity \) — Training intensity percentage (0-1)

Explanation: The formula calculates the target heart rate zone by multiplying your maximum heart rate by the desired intensity percentage.

3. Importance of Heart Rate Zones

Details: Training in specific heart rate zones helps optimize cardiovascular fitness, fat burning, endurance, and performance while preventing overtraining.

4. Using the Calculator

Tips: Enter your maximum heart rate in bpm and the desired intensity percentage (0-1). All values must be valid (MHR > 0, intensity between 0-1).

5. Frequently Asked Questions (FAQ)

Q1: How do I determine my maximum heart rate?
A: The most common method is 220 minus your age, though individual variations exist. For accuracy, consider a graded exercise test.

Q2: What are the typical heart rate zones?
A: Typically 5 zones: Zone 1 (50-60%), Zone 2 (60-70%), Zone 3 (70-80%), Zone 4 (80-90%), Zone 5 (90-100%) of maximum heart rate.

Q3: Which zone is best for fat burning?
A: Zone 2 (60-70% of MHR) is often considered the optimal fat-burning zone where your body uses fat as the primary fuel source.

Q4: Can heart rate zones vary between individuals?
A: Yes, heart rate zones can vary based on fitness level, age, genetics, and other physiological factors.

Q5: How often should I train in different zones?
A: A balanced training program typically includes time in all zones, with most time spent in lower intensity zones for base building.
