Doing sit-ups will not help you get a flat stomach! Targeted fat loss is not physically possible for anyone. You can only lose abdominal fat if you lose fat everywhere else on your body. Also, toning your abdominal muscles and losing belly fat are two completely different things. The abdominal muscle group is small, so the heat you feel while working that group out isn't close to the amount of heat needed to burn the fat.
