Cardio: "How Long Do I Do It?"

In general, the longer the duration of exercise, the greater the percentage of energy produced by fat. Keep in mind however, that during the first 20 minutes the body is merely preparing to burn fat at a more efficient rate. After the 20 minutes the body will start to metabolize stored fat at a more efficient rate. Therefore, if you wish to burn fat by exercising, you should know that patient, persistent, consistent low intensity training is the road to maximum use of fat and conservation of glycogen. It is agreed, then, that frequent hours of long and consistent exercise is the preferred methodology to optimize a fat burning metabolism. In other words, your personalized program should include exercise as much and as often as possible.
