1. What is Zone 2 Heart Rate?

Zone 2 heart rate is a moderate intensity training zone that corresponds to 60-70% of your maximum heart rate. Training in this zone improves aerobic capacity and fat metabolism.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Max\ HR \) — Maximum heart rate in beats per minute (bpm)
• \( 0.6 \) — Lower bound of Zone 2 (60% of max HR)
• \( 0.7 \) — Upper bound of Zone 2 (70% of max HR)

Explanation: The calculation provides the heart rate range that corresponds to Zone 2 aerobic training.

3. Importance of Zone 2 Training

Details: Zone 2 training improves mitochondrial function, increases fat oxidation, and builds aerobic base without excessive stress on the body.

4. Using the Calculator

Tips: Enter your maximum heart rate in bpm. For most accurate results, use a measured max HR from a stress test rather than age-predicted formulas.

5. Frequently Asked Questions (FAQ)

Q1: How do I determine my max heart rate?
A: The most accurate method is a supervised maximal exercise test. Age-based formulas (220 - age) are estimates only.

Q2: How long should I train in Zone 2?
A: Beginners might start with 30-45 minutes, while endurance athletes may do 2+ hour Zone 2 sessions.

Q3: Can I talk while in Zone 2?
A: Yes, Zone 2 should allow for comfortable conversation ("talk test").

Q4: How often should I do Zone 2 training?
A: Most training plans include 2-4 Zone 2 sessions per week, balanced with higher intensity work.

Q5: Does Zone 2 training help with fat loss?
A: Yes, it promotes fat oxidation but total calorie burn is lower than higher intensity zones.
