Well I find as I lose excess body fat my abs just naturally lean out that way, and I'm actually try to lose about 10 lbs at the moment. I make sure to do strength training as in intervals, then 3 hrs hours during the week of just hard cardio. I also make sure to eat relatively clean with lots of protein, veggies and fruit. I don't eat as much grains, dairy, breads as I have food allergies. I have a trainer at the moment who says the key to flat abs is your diet, cardio where you really work hard and suck in your ab muscles a lot of the time. That's great that the ab roller worked for you. I have a few machines at home, might even have that one. I don't know I have a tendency to buy the latest gadget and forget about it after a while?
