How to use Target Heart Rate Calculator

Type your age and optional resting pulse, and the calculator will estimate training zones you can use while walking, running, or doing cardio work.

What this calculator is for

This calculator is for exercise-intensity planning and general fitness guidance. Heart-rate zones are helpful reference bands, but medication, medical conditions, heat, and training status can all change what feels appropriate.

Tips

Check resting heart rate when you are truly at rest, ideally under similar conditions each time.
Target zones are general guides, so perceived effort and symptoms still matter during exercise.
If you take heart-rate-altering medication or have heart-related concerns, ask a clinician what zone is appropriate for you.
