Releasing the quadratus lumborum (QL) — that deep, often-overlooked muscle in your lower back, can be a game-changer for stubborn back pain. Tightness here commonly contributes to one-sided discomfort, stiffness, and even hip tension from prolonged sitting or poor posture. Active Release Technique (ART) helps reduce muscle spasms and trigger points, eases pain, improves spinal stability and flexibility, and supports better overall posture and movement. Many people notice quick relief and greater ease in daily activities once this hidden stabilizer finally lets go.
