wow, streamingbarrel, you work out hardcore!
hmmm.....everybody has different metabolisms and different builds. I know one guy that rarely exercises and has the perfect six-pack, while some guys I know exercise everyday and still have that barrel.
Only other way I can think of is a good diet. Eat lotsa fruits and vegetables, lay off on the manufactured and greasy junk food, and eat worthwhile protein, like fish and chicken (preferably not FRIED chicken).
With some luck, you'll lose some body fat so that your abs will show more.
