How do you get abs for a girl who is 11 years old?

Muscle training should be avoided, so as to avoid stunting growth, but cardiovascular sports like running, swimming, lacrosse and even dance would be a healthy way to lose tummy fat.
In this way will the natural abdomen be more exposed.

That is true but it is possible for an 11 year old girl to have abs because i have them(i bet you won't believe me) and i didn't even know i had abs for a long time. I have mine because I am really athletic and all that stuff. I even have very muscular legs and i have lots of arm muscle.

So it is possible and you pretty much just need to work out and eat right and do lot of sports.
