How can i get a six pack for teen?

Diet and exercise: Most of those ripped bodies out there have 5-10 % body fat. Since most normal appearing teens will have 15-20% that could mean dropping 5-10% of your body weight to achieve that goal. You can certainly have a flat stomach with good conditioning and less weight loss, but a good 6 pack will cost you. Competitive body builders often get into the 3-5% body fat range.
