It really does help to build the muscles up. When they push out, they become more visible. Look in the mirror, then drop and do a good ab work-out, and look again. They're probably puffy and visible now. If you can eventually manage good hypertrophy, they'll keep looking better and better. Some of us are lucky and our bodies just throw muscle on. I'm on that boat, so I can't speak for hard gainers. Cutting fat is only half the work. Adding muscle is arguably the same half.
