The Fearful or Anxious Muscle”
The psoas is a deep muscle located at the front of the hips and lower spine. It connects the lumbar spine to the femur and helps with hip flexion, walking, and stabilizing the body.
Because the psoas works closely with the diaphragm and core, stress may influence how it functions. When you feel threatened or anxious, your breathing may become shallow and your muscles may naturally increase their tension.
The psoas is not literally an “anxiety muscle,” and tension does not always mean it is the cause of pain. However, stress, breathing patterns, posture, and movement habits can all affect how your lower back and hips feel. Swipe left to learn more
Where Is the Psoas?
The psoas begins along the sides of the lower spine, travels through the pelvis, and attaches near the upper thigh. It sits deep behind the abdominal organs, which is why it cannot be easily felt from the surface.
This muscle helps lift the leg, walk, climb stairs, and transition between sitting and standing. It also works with the abdominal muscles, back muscles, pelvis, and diaphragm to support movement and stability.
When the hips and spine are not moving well together, the psoas may work harder than necessary. Long periods of sitting, repetitive movement, or poor coordination may contribute to stiffness or discomfort around the hips and lower back.
When Stress Changes Your Movement
Stress can influence breathing, posture, and muscle tension. Some people begin to breathe more shallowly, hold tension in the ribs, elevate the shoulders, or brace their abdominal and hip muscles.
Over time, these patterns may affect how the pelvis, spine, and hips move. You may notice tightness when standing upright, discomfort after sitting, restricted hip extension, or increased tension in the lower back.
This does not mean that stress is the only cause of pain. Back and hip symptoms can have many contributing factors, so persistent, severe, or worsening pain should be evaluated by a qualified healthcare professional.
Release and Rebuild
Supporting the psoas is not always about forcing it to stretch. A better approach may include comfortable breathing, gentle mobility, improved bod
