This groundbreaking book reveals how tightness in an often-overlooked hip muscle—the iliacus—can cause pain not just in the hips, but throughout the entire body. Whether you struggle with back, tailbone, pelvic, knee, or foot pain that won’t go away, the culprit may be this deeply embedded muscle. Based on decades of physical therapy experience, Christine Annie (previously Koth) guides you through a proven 3-step method to release tension, restore alignment, and reclaim pain-free movement—without costly treatments or surgery. Learn how to recognize, treat, and prevent hip flexor dysfunction so you can move freely and live fully.
