I envy your flat underbelly, it makes kilts look superb on your waist. :

The flat pelvis comes from contracting my internal oblique muscles. I started this one so long ago that I do it automatically now.. These are your abdominal corset and are not usually visible as they are covered with the external obliques and the rectus muscles down the center. Just try to make your belly button reach your spine without holding your breath. Lay flat on your back with your legs at a 45 and your feet flat on the floor. Place your hands between your pelvic points and belly button, close to the points. Try to bring in your belly button without tightening the rectus muscles (this isn't a situp).
You will feel the internal obliques tighten - it feels like a taunt sheet under your skin - when you get the right set of muscles. Hold it in as long as your comfortable can. Over time it will be longer. Soon you can do it standing, then walking and finally sitting. The more you do it the more automatic it becomes.

You don't hear about this much from the bodybuilders. There is no equipment to be sold to do this exercise.
