Super abs are never the result of just one set of exercises or even a single workout. You need to be able to train them consistently, over time with an abs workout that is doable, a little challenging but still won't stop you from doing all your other fitness related activities. Enter the Super Abs workout. Add it to your weekly routine. Follow it faithfully; and you will see and feel the difference.
Extra Credit: Do 30 crunches instead of 20.
