The best abdominal workouts combine exercises for both the upper and lower abs; crunches for the upper region and hanging leg raises for the lower region make a great workout. Former bodybuilding pro Lee Labrada offers this workout and an advance ab routine on BodyBuilding.com.
Labrada's advanced workout adds oblique work, cable crunches and the dragon flag to hit the abs from all angles with more sets and weight. Training frequency and the importance of including the obliques in ab workouts are also covered. Finally, to help accentuate the look of the "six pack," Labrada gives nutrition tips on cutting fat and eating smaller meals.
