Question: what is the fat burning zone on a treadmill?
Answer: Generally, your fat-burning zone is 70 percent of your maximum heart rate. If your max heart rate is 180 beats per minute, your fat-burning zone is 70 percent of 180, or 126 beats per minute (180 x 0.70 = 126). With this number, you'll know how hard you should work to support weight loss.
