How to Use

During exercise, you want to elevate your heart rate to strengthen your heart 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. To get your maximum heart rate, subtract your age from 220.

Use our Target Heart Rate Calculator to find the safe heart rate for people your age during exercise. If you're beginning an exercise program, aim for the low end of this range. If you’ve been exercising for a while, you can aim for a higher target rate.
