Changing your genes might help. Isn't only like 30% of the population genetically (I use this term loosely) able to have a six pack?
And while we are on the abs thing, I'm a fat guy who has found it impossible to show even the slightest hint of an ab muscle. And yes, I am jealous of you people with washboard stomachs. I have completely abandoned ab work. The reason is, I have found, the more ab work I do, the bigger my waste gets. Basically the muscle pushes out my fat even more. Gasp, I don't want to look fatter!
Having said all that, I believe I am getting enough "core" work with squats, dead lifts, hang cleans, military press, etc. without having to do ab work.
I think basically what I am saying is that if you can't see your abs, work more on losing fat than building up you abs. Finally, I have read somewhere that aspirin might help you lose the mid section fat. There are very few blood vessels in the ab fat area. Aspirin thins the blood and thus allows more blood flow to the ab area. Any comments?
You might want to try som internal abdominal work. http://exrx.net/WeightExercises/Transve ... acuum.html
It's the abdominal muscle that essentially holds your guts in. I've heard somewhere that working on this muscle may "suck in" your stomach.
