Before starting the journey to flattening your stomach you need to know about your body type because it will determine what you will do for a flat stomach.

Endomorph: Usually short and soft with under developed muscles, tends to have large amount of fat, can’t drop weight easily. Philip Seymour Hoffman and Jennifer Lopez are among famous personalities with ectomorph body type.
Mesomorph: Usually symmetrical with well developed muscles, wide shoulders and small waist. Other characteristics include low body fat and they seem to burn fat easily. Famous personalities with mesomorph body type include Arnold Schwarzenegger and Anna Kournikova.
