Floyd - First and foremost, NUTRITION! After that, there's a lot of ways to burn calories. The best is running. It's second to nothing. But if running isn't your thing, any steady state cardio that raises your heart rate for a sustained period of time is good. Walking, hills, biking, swimming, Zumba, anything like that. When it comes to steady state cardio, you burn a significant amount of calories while you're active, and when your heart rate settles, so does he metabolic calorie burn. On the other hand, resistance/weight training puts the body in a state that it continues to burn calories long after the work is done. This is a great reason for someone who wants to burn fat to do resistance training. Additionally, as you begin to build muscle, your body will become more efficient at burning fat. This is why I like to combine resistance and cardio in workouts when I can for a full metabolic response, burning the most amount of calories during the activity, building muscle, and continuing to burn calories post workout. CrossFit workouts are a great example of full metabolic response workouts (as a sports performance trainer, I can't endorse CrossFit as it's the opposite of what I do, ME = Structure, CrossFit = Unstructured). Really, the basic idea is to take some resistance exercises, add a cardio section, and do a certain amount of rounds for time. It's amazing how a workout can change when you put a clock on it. PM me if you want and I can give you some more detailed advice.
IMPORTANT DISCLAIMER - You CANNOT spot-burn fat. Your body burns fat from where it chooses, regardless of what muscles you are using. This is where women can get frustrated, because they lose curves from good places and not from where they want to lose, and guys don't really have problems with it. Plus, It's important to be well rounded. Put the work in, eat right, and the midsection fat will burn away.
