In this 45min beginner level yoga flow we're focusing on the psoas muscle.

The psoas muscles are considered the deepest of the core muscles, and there are two of such muscles. These muscles are present on either side of the torso and they connect the spine and the legs, creating a bridge between the upper and lower body. Known as hip flexors, these muscles are buried deep within the center of the body. As per the human anatomy, the psoas connects to the sympathetic nervous system which are responsible for "fight-flight-freeze".
