The main muscle that flattens your stomach is the transversus, a thin sheet of muscle to the sides of the six-pack that joins the connective tissue behind it. The transversus is your body’s natural corset. The transversus is the main muscle that pulls in your gut.

The final outer layer of muscle, which is visible, consists of the external obliques. Fibers of the external obliques run on the opposite diagonal to the internal obliques, providing a further criss-cross layer of support for the gut. They also rotate your trunk and bend it sideways, which are important functions for athletes.


Hope it helps

Best wishes

Alaa Abdulsalam
