I'm not sure what saddlebags are, but what formed my abs to me good is a short routine i do everyday. i made up my own names for these workouts cause i'm uneducated in the area.
Do crunches, one with your knees bent as close in as possigle, then half way, then legs all the way. This targets portions of abs.
Leg raises for lower abs, this is usually the most neglected part.
Lie down on your side and do a sideways sit up focusing on your side muscle.
Do the thing where you have your legs up and knees bent and you have your hands behind your head (not supporting but for positioning). and then touch your elbow to the knee of the opposite side (left elbow to right knee). doing this you will sit up a little and twist your upper body.
Mix it up when you do these. I do not build mass with this i just defined my abs. I do about 60 reps on each, with three sets.
