How do you get six pack abs if you are a kid?

Exercise and maintaining low enough body fat for abs to show through (do not over eat). If you are between 10 to 20 years. Then try playing Badminton or do sit up's every day. I am sure you will have Ab's but not 6, you will have 4. Believe me! Just try it. May be it will take 2 months if you work hard. If you are fat try running every morning and after you become slim do sit up's and crunches.
