The left and right rectus abdominis muscles lie either side of the linea alba.
The linea alba is formed by aponeuroses (thin sheets of tough connective tissue) that extend from the lateral abdominal muscles as they merge midline at the front of the abdomen.
The rectus abdominis muscles sit within the rectus sheath (a tunnel formed by the aponeuroses on their way to form the linea alba)
Connect mind and body. Feel your linea alba guide for alignment.
