This class features poses that target the quadratus lumborum. Although categorised as an abdominal muscle the quadratus lumborum is situated in the lower back either side of the lumbar spine. It connects to both the lowest rib and the top of the pelvis. It is a stabilising muscle that contributes towards good postural habits whilst standing, sitting or walking. Sedentary lifestyle or long periods spent at a desk or sitting in front of a computer can tighten this muscle and be a common cause of lower back pain. For yoga practitioners, restricted mobility in the quadratus lumborum can limit access to a range of more advanced seated poses and forward bends. This weeks advanced class contains a series of poses that will help to bring elasticity to this region of the lower back.
