OH! my Psoas... Nervous System’s First Responder
Michael Zweigart | FEB 2
The psoas isn’t just another hip flexor, it is directly connected to the central nervous system. This means the psoas isn’t just physical—it’s neurological and emotional.
It's why we often teach clients 'you are holding your emotions in your hips/pelvis.'
It's primed and ready to protect you.. makes sense why we 'always' perceive it as "tight."
When your nervous system senses a threat, the psoas responds
Fight:
The leg pulls upward to kick or protect. → Psoas activation.
Flight:
The knees drive toward the chest to run quickly. → Psoas activation.
Freeze:
The body curls inward to protect vital organs. → Psoas activation AND contraction.
So that's why the psoas is:
- gripping
- tight
- over-contracted
- hard to stretch
- reactive
- emotional
It remembers your stress—past and present.
Stretching Alone Doesn’t Work
In yoga, we often try to “stretch out” the psoas with:
- lunges
- long hip flexor holds
You can’t stretch a muscle that thinks it’s protecting you.
If the nervous system perceives threat, the psoas will tighten more.
- Gripping = safety.
- Overstretching = threat.
The psoas doesn’t need to be stretched. - It needs to feel safe.
It needs support, breath, and somatic release—not force.
A functional approach softens the psoas by supporting the nervous system:
Somatic movements
Nervous system down-regulation
Breathwork to calm protective reflexes
Functional hip mobility
Informed cueing
