What is the difference between the Karvonen method and percentage of max HR?

The Karvonen method calculates target zones using both age and resting heart rate to determine heart rate reserve, while percentage of max HR uses only age to estimate maximum heart rate. The Karvonen method is generally considered more accurate for individualized training zones.

How do I interpret the Intensity Min and Intensity Max values shown?

The Intensity Min and Intensity Max represent the lower and upper bounds of your target heart rate zone in beats per minute. Training within this range ensures you are working at the selected intensity percentage for optimal physiological benefit.

Can I use this tool if I don't know my resting heart rate?

Yes, you can use the percentage of max HR method, which only requires your age. However, entering your resting heart rate with the Karvonen method will provide more personalized and typically more accurate training zones.

Are the calculated heart rate zones a substitute for medical advice?

No, these zones are estimates designed to guide structured workouts. Always consult with a healthcare professional before starting a new exercise program, especially if you have pre-existing health conditions.
