Releasing the Iliopsoas and Quadratus Lumborum delves deeply into two muscles that play a profound role in low back and pelvic stability. This book gives you the tools and strategies to restore power, ease, and fluidity to the low back and pelvis. When these muscles becomes unable to perform their stabilizing duties due to injuries, poor posture, extended stints of sitting, or stress, they can alter the biomechanics of the pelvis and lumbar, thoracic and even cervical vertebrae. Discover gentle, effective, and new deep tissue protocols for releasing these muscles using Peggy Lamb's original and innovative Muscle Swimming approach.
