That bulge always shows up where we don't want it. On men, usually around the waist. On women, the hips, thighs and buttocks. These areas are the first place we see fat accumulate and the last place we see it disappear. This one you can blame on genetics.
The first place we usually lose fat is on our face (so our mothers can tell us we look too thin). Unfortunately, it is not possible to direct our bodies to burn fat from a particular area.
Take sit-ups for example. It is important to keep your stomach (and back) muscles in shape, and firm abs can even help to hold in your stomach. But to reduce the size of your mid-section, you would do just as well to perform any exercise that you enjoy.
Burn the calories and the fat will come off right where you want it to. It just may come off there last.
