Avoid sugar, and lower your carb intake, add more fiber foods (steel cut oatmeal, raw veggies and so on).
You want to do the same amount of reps and sets with abs then any other muscle group, anymore then no growth, interval cardio is important, raising and lowering your heart rate, no more then 40 minutes 4 times a week.
Of coarse age plays a role, how old are you? If youv'e never had definition in your lower abs then.......
