Although commonly referred to as a back muscle, the Quadratus Lumborum (QL) is part of the abdominal muscles, as it lines the back of the abdominal cavity. It attaches at the top of the pelvis, the bottom of the ribs and each of the lumbar vertebra. When one QL contracts, there is either side bending or lifting of the pelvis and when both QL’s contract, back bending occurs.
The QL becomes weak with too much sitting. Keeping your QL’s strong is important for proper walking. Strong QL’s also help with traction of the lumbar vertebrae which may help with leg numbness, tingling and weakness.
For exercises to help strengthen your QL, speak to Mike, Chip, or Sharon.
