i think its immature to be jealous of ab machines which is obviously your case. You have no facts whatever so ever, you are going on a, " I work hard 3 hours a day in the gym" basis, which I think is a little ignorant. I mean, try it first, or talk to people that have, and then make your decision by that, otherwise I am sure you are a very mature person, I really did not mean to insult you, I just think that its an ignorant perspective to assume that there could be a machine out there to help you get a more defined six pack.
