This stretch is a great way to isolate Quadratus Lumborum. 

This stretch targets the erectae spinae muscles of the whole spine. This is great for opening up the lower lumbar facet joints.

This stretch targets the psoas muscle specifically. It is a great stretch for runners.

This is a great exercise for warming up the full spine and pelvis and associated musculature. Excellent for runners in combination with SL007 and SL008. This is a good first stage spinal flossing exercise.
