If you want to reduce visceral fat, don’t exercise at a constant pace. Interval training will benefit you whether you’re trying to get fit or lose weight, and whether you’re a weekend warrior or a high-performance professional athlete.
Interval walking is one of the most convenient exercises. It doesn’t require any special equipment and can be performed anywhere. Weight training with only short periods of rest between sets (one minute) is one of the best all-around exercises, in my opinion. The anaerobic aspect of weightlifting causes muscles to fatigue rapidly. And don’t forget kettlebells, which also cause an anaerobic burn.
Finally, exercising first thing the morning before breakfast can make a tremendous difference. I exercise immediately after my morning protein shake. Exercising before eating anything might be a little better, but the main problem comes from consuming carbohydrates. If you start exercising with a belly full of carbohydrates (or one of the high-carb energy drinks in your hand), your body will use that for fuel and never have to burn any extra body fat or glycogen stores. Protein and fat take longer to digest, and when consumed immediately prior to exercise, they won’t get into the system quick enough to be used as the primary source of energy. After 45 minutes to an hour of hard exercise, protein will start to be available for muscle repair and growth.
