Just train your core like any other muscle in your body, heavy resistance training, 3-5 sets 5-10 reps close to failure, full range of motion. For the back I like Jefferson curls and full rom back extensions, for obliques I like cable twists and dumbbell side bends, for abs I like weighted crunches, leg lifts and cable crunches. No need for any separate "core routine".
