Target Heart Rate Calculator  
Note: This tool is not applicable to children. The maximum heart rate in healthy children is about 200 beats per minute. According to the American Heart Association, there is no need to arbitrarily restrict healthy children to lower heart rates.


During exercise, you want to elevate your heart rate to strengthen it while avoiding rates that endanger it. According to the American Heart Association, the best heart rates to achieve during exercise are between 50 - 85% of your maximum heart rate.

Use our Target Heart Rate Calculator to compute the appropriate heart rate for people your age to achieve during exercise. If you're beginning an exercise program, you should aim for the low end of this range. More experienced exercisers can aim for higher target rates.
