Heart Rate Zone Calculator
Estimate moderate and vigorous heart-rate zones.
Estimated max heart rate
185 bpm
Moderate zone
123-148 bpm
Vigorous zone
148-166 bpm
Formula
Max heart rate = 220 - age. Zones use resting heart rate plus a percentage of reserve.
Assumptions
- Uses the simple 220 - age maximum heart-rate estimate.
- Measured max heart rate or clinician guidance is more accurate for training plans.
- Not suitable for people taking heart-rate-altering medications or managing cardiac conditions without clinician guidance.
The heart-rate zone calculator estimates max heart rate and target zones using heart-rate reserve.
How to Use
The heart-rate zone calculator estimates max heart rate and target zones using heart-rate reserve. Enter the Age and Resting heart rate values and review the Estimated max heart rate, Moderate zone, and Vigorous zone outputs after you calculate.
