The Rectus Abdominis is a long, flat muscle located in the front of the abdomen. It extends from the pubic bone to the lower ribs and is commonly referred to as the "abs." This muscle plays a crucial role in flexing the spine, helping with movements like bending forward and maintaining good posture. In addition to its primary function, the Rectus Abdominis also supports internal organs and contributes to core stability. Strengthening this muscle can improve athletic performance and reduce the risk of injury. Exercises like crunches and planks are effective for targeting the Rectus Abdominis.
