Any workouts for girls wanting six packs?

I'm sixteen and I'm comfortable with my weight (about 120-125), I am in shape, my tummy is normally flat unless I've just eaten a big meal, and I am very determined. But I would really like to bump up workouts because I've been getting lax and I want more to do during the summer when I'm bored. Are there any workouts out there to get a six pack for a girl? Diet tips would be good too since I am a food aholic.
