Abs are like any other muscle. If you want them to be stronger, slap a 45Lb (or whatever you can handle) plate on your chest and do crunches, and no more than 3 times a week. And be smart about it, do 2 or 3 sets max with between 8 and 12 reps.

If you want more definition, lose fat. Yeah, working the abs will make them a little bigger, and thus sometimes easier to see.

Another thing to consider is that abs are genetic. Not everyone is able to get a 6 or 8 pack.
