The order of the abdominals from deepest to most superficial is?

The order of the abdominal muscles from deepest to most superficial is accurately represented by the selection. The transverse abdominis is the deepest layer, functioning primarily to stabilize the pelvis and lower back before movements occur. It acts like a corset around the torso, compressing the abdominal contents and playing a crucial role in core stability.

Following the transverse abdominis are the internal obliques, which lie above it and contribute to trunk rotation and lateral flexion while also aiding in compression of the abdominal cavity. Surface to the internal obliques are the external obliques, which are responsible for trunk rotation as well and offer support during lateral movements. Finally, the rectus abdominis, commonly referred to as the "six-pack," is the most superficial layer and primarily functions in flexing the spine.

Understanding the arrangement and function of these abdominal muscles is essential for effective movement training and injury prevention. Each layer plays distinct and significant roles in core stability and abdominal function, thus reinforcing the importance of training them in proper sequence and awareness of their interactions.
