Who would prefer just a gentle relaxing massage instead of a deep tissue style?
Honestly, I can do both. 🫣
But when I see a rotated or tilted pelvis and there is pain involved this is what I'm working to rectify. 😬

If you are wanting a Relaxation Massage instead, just be stern and direct with me. 😆
Some people actually ask for a flogging though. 😂
HIP FLEXOR & LUMBAR STABILIZER ANATOMY – A DEEP LOOK
The psoas major, iliacus, and quadratus lumborum together form a powerful anatomical complex that links the lumbar spine to the pelvis and lower limb. These muscles are not just movers of the hip—they are key stabilizers of posture, gait, and lumbopelvic control, making them clinically and functionally significant.
The psoas major originates from the transverse processes, vertebral bodies, and intervertebral discs of T12 to L5. It descends anterior to the pelvis, passing over the pelvic brim, and inserts onto the lesser trochanter of the femur. Due to its direct attachment to the lumbar spine, the psoas major has a dual role: it acts as a primary hip flexor and also exerts significant influence on lumbar lordosis and spinal stability.
The iliacus muscle occupies the iliac fossa on the inner surface of the pelvis. It arises from the iliac crest, iliac fossa, and anterior sacroiliac ligaments. Distally, it merges with the psoas major tendon to form the iliopsoas, inserting on the lesser trochanter. Unlike the psoas, the iliacus has no spinal attachment, making it a pure hip flexor with strong influence on pelvic positioning rather than spinal motion.
The quadratus lumborum lies posteriorly in the abdominal wall, spanning from the iliac crest to the 12th rib and transverse processes of L1–L4. It forms a muscular bridge between the pelvis and the lumbar spine. Anatomically, it is positioned to control frontal-plane motion of the trunk and pelvis, especially during single-leg stance activities such as walking.
Together, these muscles create a functional sling that stabilizes the lumbopelvic-hip complex. Their anatomical orientation allows coordinated control of hip flexion, pelvic tilt, lumbar curvature, and trunk alignment. Any imbalance—tightness, weakness, or asymmetry—can significantly affect posture, gait efficiency, and load transmission through the spine and lower limbs.
Clinically, understanding the anatomy of this muscle group is essential when addressing low back pain, hip dysfunction, gait deviations, and postural disorders. Their deep location and close relationship with neural and skeletal structures make them critical targets in both assessment and rehabilitation.
