Side abs, no front abs?

Hi ladies,

I currently work out 3 days per week on a Butt/Legs, Chest/Back, and Abs/Shoulders split. I incorporate some abs in all my workouts, plus I do on average 2 additional ab workouts per week after cardio. My movements include leg raises (hanging and lying), crunches of all kinds, Russian twists, and planks.

My question is: I see a lot of definition down the sides of my abs (my obliques, I guess) but not down the front (a la the classic 6-pack). See my profile pic for an example. Any tips on how to develop the definition across the front and down the middle? I read that hanging leg raises are supposed to do so -- maybe I should up the number of those?

Thanks in advance! :)
