Well , Im 13 110 pounds and 5'6 . I have a big stomach ,and my pecs are a little big to .Im starting to run 2Kilometres every day now,And im starting to do some ab exercises .When i flex i can see my 4 pack but when i dont flex my stomach kind of buldges out. If i continue running everyday 2km than doing ab exercises ,AND cutting down more on the junk food and start going more to fruits , like strawberrys ,oranges and Bananas. >>WILL I SEE A DIFFERENCE?<<
