run at an oblique angle to vertical direction of the spine.
The external oblique muscles form the external lateral walls of the abdomen. These muscles run diagonally down and towards the midline of the body, aiding in movements like trunk flexion and rotation.
The internal oblique muscles help with trunk rotation and bending, while the external oblique muscles assist with trunk flexion and rotation.
The function of the external oblique is to pull the chest downward and compress the abdominal cavity. In other words, it helps you bend over.

There are 4 muscles that make up your abdominal muscle anatomy: rectus abdominis, external oblique, internal oblique, and transverse abdominis.
