1. What is the Heart Rate Zone Calculator?

The Heart Rate Zone Calculator using the Reserve method estimates your target training zone based on your Heart Rate Reserve (HRR), desired intensity percentage, and resting heart rate. This method provides more personalized results than simple percentage of maximum heart rate.

2. How Does the Calculator Work?

The calculator uses the Heart Rate Reserve equation:

Where:

• \( HRR \) — Heart Rate Reserve (Maximum HR - Resting HR)
• \( Intensity \) — Desired training intensity as percentage
• \( Resting\ HR \) — Your resting heart rate in bpm

Explanation: The equation accounts for your personal heart rate range by incorporating both your maximum capacity (through HRR) and baseline (resting HR).

3. Importance of Heart Rate Zones

Details: Training in specific heart rate zones helps optimize workouts for different goals (fat burning, endurance, performance) and ensures you're working at the right intensity.

4. Using the Calculator

Tips: Enter your HRR (if known, or calculate as Max HR - Resting HR), desired intensity percentage (typically 50-85% for training zones), and your measured resting heart rate (best taken in the morning before getting out of bed).

5. Frequently Asked Questions (FAQ)

Q1: How do I find my maximum heart rate?
A: The most accurate method is a supervised stress test. The common "220 - age" formula is an estimate with limited accuracy.

Q2: What are typical heart rate zones?
A: Common zones are: 50-60% (very light), 60-70% (light), 70-80% (moderate), 80-90% (hard), 90-100% (maximum).

Q3: When should I measure resting heart rate?
A: Measure first thing in the morning, before getting out of bed, after several days of normal sleep.

Q4: Why use HRR instead of max HR?
A: HRR accounts for your actual working heart rate range, making zones more personalized and accurate.

Q5: How often should I check my zones?
A: Reassess every 3-6 months or after significant changes in fitness level, as your resting HR may decrease with improved fitness.
