Going by several different names such as the lumbodorsal fascia or thoracodorsal fascia, the thoracolumbar fascia is a thick layer of fascia on the back of the body. It surrounds many muscles and serves as an attachment point for many others such as the lats and internal obliques. Sometimes, what we perceive as tightness of the muscles of the low back is in fact restriction of the thoracolumbar fascia. To determine if it's the fascia stopping you and not the muscles, here's a simple test. From a seated position, see how far you can twist to the left and the right. Now put your arms out in front of you, palms up, pinky to pinky, and again twist to the left and right. If you can twist further with your arms down, the fascia is limiting your motion. Consider getting evaluated by a good therapist if it's restricted. It can happen for many different reasons and the treatment varies depending.
