Fat Burning Zone

Let's face it. Most of us do cardio to burn fat and look better. The tricky part is figuring out how much you have to raise your heart rate through intensity of exercise to get in your target heart zone. An easy formula is take the number 220 minus your age. You then take that number and multiply it by .60 and .70 because your body burns fat most efficiently when we exercise between 60 and 70 percent of our maximum heart rate capacity. Here is an example: I am 48 so 220-48 =172.  172x.6=103 and 172x.7=120. So my target heart rate is between 103-120 if I am trying to burn fat most efficiently.
