ab exercises?

[coolperson1227]

hi everyone.
i was wondering if you could tell me any ab exercises you know(besides crunches, situps, and plank)?
thanks! i'm kinda getting bored of those.
[if needed] i'm a 14 year old girl so tell me exercises suitable for me :)

Here's the routine I do in my PE class. I think it's great because it works each set of abdominals individually. Start by doing like 20 reps of each of these, and then gradually increase that number as you get stronger:

-Crunches with ankles crossed above the floor, knees at 90 degrees
-Crunches with your legs straight out flat on the floor.
-Crunches with your legs folded to the right side.
-Crunches with your legs folded to the left side.
-Leg lifts going from 3-6 inches off the floor to a foot off the floor.

It's amazing how much it helped me doing these exercises freshmen year. I'm a cross country runner, and having a strong core made me faster. Hope this helps!
