Heart Rate Zone Calculator
Estimate your target heart rate zone based on your age, resting heart rate, and fitness goal.
What Heart Rate Zones Mean
Heart rate zones help you understand how hard your heart is working during exercise. Lower zones are easier and better for warm-ups or fat burn, while higher zones are more intense.
Why Resting Heart Rate Matters
Your resting heart rate helps estimate your heart rate reserve, which gives a more personal target range.
