Free Target Heart Rate Calculator

Find your training heart rate zones using the Karvonen method.

The Karvonen method uses "heart rate reserve" (max HR minus resting HR) rather than just a percentage of max HR, which better accounts for individual fitness levels. Moderate-intensity exercise is typically 50-70% of heart rate reserve; vigorous is 70-85%.
