If a flat stomach is your goal, the exercises listed below will engage your inner core (TVA, erector spinae, multifidus, longissimus, diaphragm and pelvic muscles) and help build a strong and stable unit.
Oscillating Plank on a Ball
Moving Plank Contralateral lifts
Low/High Wood Chops
Vacuum Exercise (isometric)
This is just a sprinkling of core exercises that don't involve a crunch, there are many more. Play around with your exercise program, hire a trainer and find what works best for you. The thing is, if we didn't spend most of our days sitting we'd wouldn't have to work so hard for a flat stomach to begin with. I guess this is another one of our first world problems.
