i'm a girl, age 15, and i've had a sixpack since about age 12 i am pretty thin and i do a fair bit of situps every day and also jogging and i have very little body fat. they say that they tend to disappear at about age 17. but i heard it's not nice for girls to have sixpacks - it's for the men! i tried to eat more and gain weight, but it's still there... and the thing is it doesn't go away even when i don't flex... it's kinda embarrassing being around boys when your ab muscles show more than theirs.... can any1 tell me how to get 'normal abs'?
