The ‘fat burning zone’ is where you are working out at about 70 – 80% of your maximum heart rate, also known as your fat burning heart rate. To determine your maximum heart rate, subtract your age from 220. For example, a 35-year-old woman's maximum heart rate is 220 minus 35 — or 185 beats per minute. To enter the fat-burning zone, she'd want her heart rate to be 70 percent of 185, which is about 130 beats per minute.
