1. What is Zone 2 Heart Rate?

Zone 2 heart rate is a moderate intensity training zone that improves aerobic base and endurance. It's typically 60-70% of your heart rate reserve (the difference between maximum and resting heart rate).

2. How Does the Calculator Work?

The calculator uses the Zone 2 heart rate formula:

Where:

• \( \text{MHR} \) — Maximum heart rate (bpm)
• \( \text{RHR} \) — Resting heart rate (bpm)
• 0.6 — Lower boundary of Zone 2 (60% of heart rate reserve)
• 0.7 — Upper boundary of Zone 2 (70% of heart rate reserve)

Explanation: The formula calculates your personalized Zone 2 range based on your individual heart rate characteristics.

3. Importance of Zone 2 Training

Details: Training in Zone 2 improves aerobic capacity, increases fat metabolism, enhances endurance, and promotes recovery. It's considered the foundation for endurance athletes.

4. Using the Calculator

Tips: Enter your maximum heart rate (MHR) and resting heart rate (RHR) in beats per minute (bpm). For best results, measure your RHR in the morning before getting out of bed.

5. Frequently Asked Questions (FAQ)

Q1: How do I determine my maximum heart rate?
A: The most accurate method is a supervised stress test. The common formula (220 - age) is only an estimate.

Q2: What are the benefits of Zone 2 training?
A: Improved aerobic efficiency, increased mitochondrial density, better fat utilization, and enhanced recovery.

Q3: How often should I train in Zone 2?
A: Most endurance athletes spend 80% of their training time in Zone 2, with 20% in higher intensity zones.

Q4: Can I talk while in Zone 2?
A: Yes, Zone 2 should feel comfortable enough to hold a conversation (the "talk test").

Q5: Is Zone 2 the same for everyone?
A: No, it's personalized based on your individual heart rate characteristics and fitness level.
