The Psoas Major is a deep core stabilizer and one of the most powerful hip flexors in the human body. It originates from the lumbar vertebrae and inserts into the lesser trochanter of the femur, enabling hip flexion, external rotation, and lumbar spine stabilization. This muscle plays a critical role in walking, running, maintaining upright posture, and transferring forces between the spine and lower limb. Weakness or tightness in the psoas can lead to low back pain, pelvic imbalance, or gait dy
