1. What is Zone 2 Heart Rate?

Zone 2 heart rate refers to a specific training intensity range that corresponds to 80-90% of your Lactate Threshold Heart Rate (LTHR). This zone is ideal for building aerobic endurance and fat metabolism efficiency in cycling.

2. How Does the Calculator Work?

The calculator uses the Zone 2 formula:

Where:

• \( LTHR \) — Lactate Threshold Heart Rate (bpm)
• \( 0.8 \) — Lower boundary multiplier
• \( 0.9 \) — Upper boundary multiplier

Explanation: The formula calculates the optimal heart rate range for Zone 2 training based on your individual lactate threshold.

3. Importance of Zone 2 Training

Details: Zone 2 training is crucial for developing aerobic base, improving mitochondrial density, enhancing fat utilization, and building endurance without excessive fatigue.

4. Using the Calculator

Tips: Enter your Lactate Threshold Heart Rate (LTHR) in beats per minute (bpm). The value must be greater than 0 for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: How do I determine my LTHR?
A: LTHR can be determined through field tests (e.g., 30-minute time trial) or laboratory testing measuring blood lactate levels.

Q2: What are the benefits of Zone 2 training?
A: Improved aerobic capacity, increased fat metabolism, better recovery, and enhanced endurance performance.

Q3: How often should I train in Zone 2?
A: Most endurance athletes benefit from 2-4 Zone 2 sessions per week, depending on training phase and goals.

Q4: Can Zone 2 training help with weight loss?
A: Yes, Zone 2 training is excellent for fat burning as it primarily uses fat as fuel source at this intensity.

Q5: Is Zone 2 the same for everyone?
A: No, Zone 2 is individual and varies based on fitness level, age, and training background.
