Fat-burning heart rate chart
When using the following chart, keep in mind that the older you are, the lower your fat-burning heart rate. For example, if you’re 32, you’d want to use the higher number in the 31 to 35 range for your fat-burning heart rate.
Certain medications may affect your heart rate, too, so speak with your doctor if you have concerns.
