yea well i have a 8 pak and im only 13 - and im not jus making it up, and yea it totally genetic - but with more excercise and workouts you can gets the 7th and 8th to show more - i dont go to a gym and do all of that - im just active and healthy, i do swimming, running, cross country, baseball, football (soccer) and in gym in school we do other sports, u dont need to go to a gym to get fit, you can easily do it by just doing a little bit each day, like 50 sit ups and go for a walk or run in the evening or morning, i personally dont do that, i just stay active, but during the summer i am extra fit because we have a cottage on a lake and go swiiming like multiple times every day and do like 2 or more miles worth of swimming a day, plus im always running around, going for walk or runs around where our cottage is, and just other activities, and i dont need to flex my stomach to see my 6 pak, but to see the 8 pak more clearly i flex it
