The only way to get rid of abdominal fat is to reduce overall body fat. No amount of situps or crunches reduces the stubborn fat that is present around the abdominal muscles.
It is often thought that doing many abdominal exercises reduces belly fat, but that is not the case. These exercises definitely strengthen the abdominal muscles, but do not actually eliminate the fat that conceals them. In order to reduce abdominal and overall body fat, it is important to include aerobic exercises as part of a comprehensive fitness program and to follow a healthy, well-balanced diet that is low in fat.
