Anatomy of the psoas The psoas muscle is a long, ribbon-shaped muscle that starts at your lower back, and runs down through your pelvis where it joins the iliacus and connects to the top of your thigh bone (lesser trochanters). You can’t talk or work on the psoas muscle without also mentioning the iliacus. Together, these muscles are known as the iliopsoas muscle and they form the strongest of the hip flexor muscles while also supporting your spine. #anatomy | YOGABODY

The psoas muscle runs from the lower spine to the inside of the femur. When it contracts, it pulls the pelvis into hip flexion (hip bend). This often forces the lower back into compensatory extension, which over time can create dysfunction and pain. Because the psoas is such a deep core muscle, it’s not easy to access directly. In this fascia decompression position, the goal is to release fascial tension in the abdominal region. By easing that tension, we can help the psoas relax, reduce stress

🔥 The psoas major creates two joint actions. One is hip flexion, what is the second? Vote now! 🔥 A. Hip Adduction B. Knee Flexion C. Hip Extension D. Lateral Flexion of the Spine 💡 Why it matters: The psoas major plays an important role in both hip and spinal movement. Understanding how this muscle works will help you assess functional movement patterns and improve exercise selection for clients dealing with lower body and core strength. ✅ Check the answer and explanation in the comments! #Ps

Psoas major anatomy: The psoas major is a deep muscle that originates from the transverse processes, vertebral bodies, and intervertebral discs of T12 to L5. It travels downward through the pelvic cavity, passes deep to the inguinal ligament, and inserts into the lesser trochanter of the femur. Along its course, it lies adjacent to the lumbar plexus, ureter, and abdominal aorta. It’s innervated by branches of the lumbar plexus, primarily from spinal nerves L1 to L3, and occasionally L4.
