Having a six-pack is not high on my priority list. Eventually I would like to have a flat stomach but that is a whole 'nother thing.

I read months and months ago when I briefly got back into some lifting, from a book called Weight Training for Dummies, or fitness for dummies or someething like that. The lady that wrote said it was a myth that anyone, without enough hard work can get a six-pack. She said it was all genetic. That if one did not have the genes, one could not get a six-pack no matter how hard they tried. What do you guys think of this?
To me, it just does not make sense how if someone brings their bf% down super low, and they still can't have a six pack. But that's is with my limitied knowledge
