The best abs exercises are ones that work more than just one part of your abdominal muscles. Yes, there are multiple layers of muscles that make up the full abdominal wall. And even though you can't see or really feel them all, they're really important for keeping your entire body strong and stable.The rectus abdominis is the muscle you think of when you think “abs.” It's the outermost abdominal muscle, and runs vertically along each side of your abdominal wall.
