Pictured above is the quadratus lumborum (QL). It is one of the deepest of the lower back stabilizers and it hikes your hip (pulls your hip up toward your spine).
It is commonly too tight in persons diagnosed with one leg longer than the other. You can't move your hip or lower back in any direction without using this muscle. 80% of all adults over 18 years of age have some form of back pain. If you aren't checking the QL for excessive tension you are missing one of the most significant links to proper back function.
The muscles are layered, showing how some of the muscles are covered by the others. All of the muscles are see-through so that you can appreciate the location and size of each muscle relative to the others.
