אני יצטט את הרשום , זה נשמע די אמין אבל עדין לא בטוח :Working aerobically on your abdominal muscles for 7 minutes stimulates the capillaries in this area these in turn increase the blood flow.

Toned muscles need more calories to stay active. our organism tends to release these calories from the area nearest the muscle , in this case the waist area.
