Forget EVERYTHING you know about ab exercises, Wendy Toth of Weight Watchers Magazine debunks the myth that crunches are king when it comes to flat abs!
She found that crunches will tone one section of your abs, but they won’t get you a flat stomach and here’s why:
As you crunch you’re engaging your upper and middle rectus muscle (aka six-pack muscle) and giving the transversus abdominis (the corset muscle that wraps around your entire midsection) only a little work. This is not enough to create the definition you’re looking for.
