My bmi is 18 but i still have slight belly fat. are there any exercises to reduce the fat without reducing my bmi so that it is too low.

One program that: Exercises your abdominal muscles. You lose fat by losing weight (3500 calories to the pound) but it is difficult to tell your body when to pull the fat from. Abdominal exercise can improve the muscles in your abdomen below the fat, and improve your physique. If you are overweight, you often are Insulin resistant, and the weight is stored in your abdomen. Overall weight loss will help.
