As a new mom wanting to get a flat stomach, I see women doing endless crunches… This is the worst thing possible for them.  I worked with a mother who did just that and had a 4 finger separation in her abdomen because the outer abdominal muscles (rectus abdominus) were pulled too far apart from pregnancy and never given a chance to be pulled in.  In this video Jill and I will demonstrate an amazing exercise that can help pull that stomach back in!
