I done the 'Abs diet' for 6 weeks. Not really a diet but just literally cutting the crap out and eating healthy, as well as exercising of course. On that routine it allows you one day a week where you can eat anything you like. ANYTHING. This way your body is not being forced to takes huge difference in what you consume. It kind of balances it out and makes the whole thing a bit easier for you.
Me personally, im doing it for myself. I wanna look good on a beach. I suppose everyone wishes they were the perfect person. Nobody is. Well, apart from Jennifer Ellison or the entire cast of Hollyoaks but lets not go there.
Why do men want a 6 pack? Who knows? I think its something like; If a man has a 6-pack it symbolises strength and power. Some women like that and hence like the 6-pack. Though not all. My ex never liked it. Thats why im doing it now.
