"The Psoas Solution" is the first book to comprehensively discuss the function of the psoas muscle in posture, movement, and athletic activity. It highlights the functional anatomy, biomechanics, and motor control of the psoas and its role in core and hip stabilization. Richly illustrated with color illustrations throughout, the book also provides a complete review of available relevant research on the psoas. Combining this research with his clinical experience, Evan Osar defines the role of the psoas in the hip, pelvis, and low back and demonstrates how to incorporate this muscle into functional movement patterns, including squat, lunge, and flexion. "The Psoas Solution" includes step-by-step exercises to correct and improve functionality to the psoas in everyday activities such as sitting and standing.
