1. What is Heart Rate Zone?

Heart rate zones are ranges that indicate different levels of exercise intensity. They are calculated based on your heart rate reserve (HRR), which is the difference between your maximum heart rate and resting heart rate.

2. How Does the Calculator Work?

The calculator uses the heart rate zone formula:

Where:

• \( HRR \) — Heart rate reserve (Maximum HR - Resting HR)
• \( Intensity \) — Percentage of maximum effort (as decimal)
• \( RHR \) — Resting heart rate

Explanation: This formula calculates the target heart rate for a specific training zone based on your personal heart rate characteristics.

3. Importance of Heart Rate Zones

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

4. Using the Calculator

Tips: Enter your heart rate reserve (HRR) in bpm, the desired intensity percentage, and your resting heart rate (RHR). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I determine my HRR?
A: HRR is calculated as Maximum Heart Rate minus Resting Heart Rate. Maximum HR can be estimated as 220 minus your age.

Q2: What are typical heart rate zones?
A: Common zones are: Zone 1 (50-60% HRR) for warm-up, Zone 2 (60-70%) for fat burning, Zone 3 (70-80%) for aerobic, Zone 4 (80-90%) for anaerobic, Zone 5 (90-100%) for maximum effort.

Q3: When should I measure my resting heart rate?
A: Measure first thing in the morning before getting out of bed for most accurate RHR measurement.

Q4: Are there limitations to this calculation?
A: Individual variations exist, and those on certain medications or with heart conditions should consult a doctor before using HR zones for training.

Q5: Should I use this for all my workouts?
A: Different workouts target different zones. A balanced training program typically includes time in multiple zones.
