Located deep within the anterior hip joint and lower spine, the psoas major (usually just referred to as the psoas) is critical for optimal postural alignment, movement, and overall well being. The psoas is the only muscle in the human organism that connects the upper body to the lower body, and its importance extends to the nerve complex and energy systems. As modern-day populations grow more sedentary, psoas-related lower back and hip pain, and the ailment of "sitting too much," are on the rise.
