Have you ever seen a really muscular abdomen? It kind of looks like six rounded protrusions, three on the left and three on the right, or like some people say, “a six-pack.” This is the rectus (straight in Latin) and abdominus, (the abdomen.) It has this name because it is the muscle that goes straight down the abdomen. This muscle is attached to the ribs as well as the pelvis and effects the moving forward of your body, like in a crunch. Together with the other core muscles the rectus abdominus keeps your spine stable and helps support your pelvis.
