Quadratus Lumborum (QL) A Real Pain In The Back!

I have written about a number of the “lightning rod” muscles such as the piriformis, psoas, and transverse abdominis. I refer to them as “lightning rods” because they attract attention. Sometimes this is for good reason, after all, everyone should know about his or her psoas. However, every problem related to core shouldn’t be thrown onto the back of the psoas or the transverse abdominis for that matter.
