What does the external and internal obliques?

The external and internal obliques are muscles located on the sides of the abdomen. The external obliques are the outermost layer, responsible for trunk rotation and lateral flexion, while also aiding in flexing the spine and compressing abdominal contents. The internal obliques lie beneath the external obliques and perform similar functions, assisting in trunk rotation and maintaining core stability. Together, they play a crucial role in movements involving twisting and bending, as well as supporting posture and protecting internal organs.
