Скачать или смотреть Abdominal Muscles

There are four layers of abdominal muscles. In this video, we'll show you three of them and explore their unique fiber directions which allows for various movements of the trunk.

The most superficial layer is the external oblique. Deep to that is the internal oblique which has the opposite fiber direction from the external oblique. The deepest layer is the transversus abdominis where its fibers are aligned horizontally to allow for compression of the abdominal contents (kind of like a corset).

You may think your "core" is just in the front where your "six-pack abs" are. But these abdominal muscles wrap all the way around to the spine as well.
