The Psoas: Your Deep Core Survival Muscle
The psoas (pronounced so-az) is one of the most important muscles in the body, yet many people have never heard of it. It attaches from the lower spine through the pelvis to the top of the femur, connecting your spine to your legs. It helps you walk, lift your knees, stabilize your low back, support posture, and even influences how you breathe.
But the psoas is more than a movement muscle—it is often called the muscle of the soul because of its close relationship to the nervous system and emotional stress patterns.
When you experience stress, fear, trauma, or constant pressure, your body activates the fight, flight, or freeze response. The psoas contracts to prepare you to run, curl inward, brace, or protect yourself. This is a natural survival mechanism.
The problem is many people never fully discharge that stress. Instead, the body stays subtly guarded. Over time, the psoas can remain shortened, tight, or overactive.
This may contribute to:
✨ Low back pain
✨ Hip tightness
✨ Sciatica-like symptoms
✨ Shallow breathing
✨ Anxiety or feeling “on edge”
✨ Poor posture
✨ Pelvic tension
✨ Digestive discomfort
✨ Difficulty relaxing
Because the psoas sits deep near the diaphragm, kidneys, intestines, and solar plexus region, chronic tension there can feel physical and emotional.
Gentle positions like hanging one leg off the bed, supported stretching, diaphragmatic breathing, somatic work, and Myofascial Release can help the body feel safe enough to let go.
Healing the psoas is often not about forcing a stretch—it’s about signaling safety to the nervous system.
Sometimes low back pain is not just structural. Sometimes it’s the body still carrying yesterday’s stress.
When the psoas softens, many people feel grounded, calmer, taller, and more at peace.
