In addition, the crunches and a total body workout (with weight training) helps the body to increase muscle mass. Muscles burn fat; fat does not burn itself so, the more muscle we have, the more fat our body uses for energy, so we lose weigh faster. If you only do crunches, you will develop your abdominal muscles and strengthen them. This will reflect in better posture and less back problems, but you will not be able to see your abdominal muscles because they will be covered with fat.
Myth No. 3: Exercise is more important that nutrition.
Fact: Diet is one of the key factor when trying to get a flat tummy. Plan your nutrition in advance, to avoid dietary downfalls. Focus on protein, green vegetables, fiber-rich fruits, and zero calorie drinks such as Green Tea and water. Avoid all sugar.
