1. What Are Heart Rate Zones?

Heart rate zones are ranges that correspond to different intensity levels of exercise. They are calculated as percentages of your maximum heart rate and help cyclists train at the right intensity for their goals.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( HR_{zone_i} \) — Heart rate for zone i (bpm)
• \( HR_{max} \) — Maximum heart rate (220 - age)
• \( zone\_percentage_i \) — Percentage for each zone

Explanation: The calculator estimates your maximum heart rate based on age, then calculates the heart rate ranges for six common training zones.

3. Importance of Heart Rate Zones

Details: Training in specific heart rate zones helps optimize workouts for different goals like endurance, fat burning, or performance improvement.

4. Using the Calculator

Tips: Enter your age in years. The calculator will estimate your maximum heart rate and show the corresponding training zones.

5. Frequently Asked Questions (FAQ)

Q1: Is 220-age accurate for everyone?
A: It's a general estimate. Individual max HR can vary by ±10-20 bpm. For precise measurements, consider a max HR test.

Q2: What are the typical zone percentages?
A: Common zones are: Recovery (50-60%), Endurance (60-70%), Tempo (70-80%), Threshold (80-90%), VO2 Max (90-100%), Anaerobic (100%+).

Q3: Should I always train in higher zones?
A: No. Most training should be in zones 2-3. Higher zones are for specific workouts and should be limited to avoid overtraining.

Q4: How does fitness affect heart rate zones?
A: As fitness improves, you may be able to sustain higher power outputs at lower heart rates (improved efficiency).

Q5: Are there alternatives to HR-based training?
A: Yes, power-based training (using watts) is another effective method, especially for cyclists with power meters.
