The Psoas is...

(A) A remote tribe in Papua, New Guinea. (B) A revolutionary computer operating system. (C) The muscle that is the key to your structural stability.
By Liz Koch

If you guessed C, you're correct. Buried deep within the core of your body, the psoas (pronounced "so-az") affects every facet of your life, from your physical well-being to who you feel yourself to be and how you relate to the world. A bridge linking the trunk to the legs, the psoas is critical for balanced alignment, proper joint rotation, and full muscular range of motion. In yoga, the psoas plays an important role in every asana. In backbends, a released psoas allows the front of the thighs to lengthen and the leg to move independently from the pelvis. In standing poses and forward bends, the thighs can't fully rotate outward unless the psoas releases. All yoga poses are enhanced by a released rather than shortened psoas. (When you reverse your orientation to gravity in inversions, however, the psoas must be toned as well as released to maintain proper spinal stability.) 

Whether you suffer from a sore back or anxiety, from knee strain or exhaustion, there's a good chance that a constricted psoas muscle might be contributing to your woes. Getting in touch with this deeply buried muscle can be humbling at first. You may discover that you've been doing many poses by contracting your core, instead of relying on your skeleton for support and allowing your more peripheral muscles to organize around a toned but flowing and spacious center. But if you persevere, psoas work can add new insight, openness, and stability to your practice. Though your psoas may not be as easy to sense as your biceps or hamstrings, improving your awareness of this crucial muscle can greatly enhance your physical and emotional health.
