After 30 minutes of aerobic exercise, you can start burning fat, but you can do anaerobic equipment exercise (strength training) for half an hour before. Strength training is very useful for reducing fat. You can consume a lot of glycogen in your body, and then you can burn fat effectively on the treadmill. You can run for 30 minutes (because anaerobic exercise has consumed glycogen). Don't rest after anaerobic exercise. You can jog because there is no fat-reducing effect after your heart rate returns to normal.
