Reducing fat from all areas of your body is imperative if you want to get ripped abs. As you begin to lose that fatty covering of your mid section, you'll need to start doing ab specific exercises to develop a tight, defined, absolutely awesome frontal core.
The following program should be done 3 times a week at a time separate to your main workouts. Perform 25 reps on each and every exercise. The complete ab workout will take no more than 12 minutes.
