Heart Rate Reserve Formula:
| From: | To: |
The Heart Rate Reserve (HRR) method calculates exercise intensity zones based on the difference between your maximum heart rate and resting heart rate. It provides a more personalized approach to training than using percentages of maximum heart rate alone.
The calculator uses the Heart Rate Reserve formula:
Where:
Explanation: The equation calculates your target heart rate zone by adding a percentage of your heart rate reserve to your resting heart rate.
Details: Calculating accurate heart rate zones is crucial for effective training, ensuring you're working at the right intensity for your fitness goals, whether it's fat burning, endurance building, or peak performance training.
Tips: Enter your resting heart rate (measured in the morning before getting out of bed), your heart rate reserve (max HR minus resting HR), and the percentage of HRR you want to target. All values must be valid (RHR > 0, HRR > 0, percentage between 0-1).
Q1: How do I measure my resting heart rate?
A: Measure your pulse for 60 seconds first thing in the morning before getting out of bed. Do this for several days and take the average for the most accurate reading.
Q2: How do I calculate my heart rate reserve?
A: HRR = Maximum Heart Rate - Resting Heart Rate. Maximum heart rate can be estimated as 220 - age, though individual variation exists.
Q3: What percentages should I use for different training zones?
A: Typically: 50-60% for warm-up/cool-down, 60-70% for fat burning, 70-80% for aerobic, 80-90% for anaerobic, and 90-100% for maximum effort.
Q4: Why use HRR instead of just maximum heart rate?
A: HRR accounts for your individual resting heart rate, providing a more personalized and accurate training zone calculation.
Q5: How often should I recalculate my zones?
A: As your fitness improves, your resting heart rate may decrease. Recalculate every 4-6 weeks or whenever you notice significant changes in your resting heart rate.
