How It Works
The calculator estimates maximum heart rate, then multiplies it by common intensity ranges to show light, moderate, vigorous, and high-intensity zones.
Example
For age 30, estimated max heart rate is 190 bpm. A moderate 50–70% zone is about 95–133 bpm.
Frequently Asked Questions
How is maximum heart rate estimated?
This draft uses the simple 220 minus age formula, which is common but approximate.
Should everyone use these zones?
No. Health conditions, medications, fitness level, and clinical guidance can change safe exercise intensity.
Is this medical advice?
No. Health and fitness calculators provide general estimates only and cannot replace personalized advice from a clinician, dietitian, or coach.
Why might my actual result differ?
Age, sex, body composition, medication, training history, health conditions, and measurement error can all affect real-world results.
