Ok Fixmyfitnessclub.com fans…the QL is found on either side of the lumbar spine. They attach to the iliac crest (top of the hip bone), the transverse processes of the L1- L4 (lumbar vertebrae) and the twelfth rib (your last rib). Essentially they connect the hip to the lumbar spine and the lowest part of the rib cage. I call it a “Hip Hiker” 
Actions of the QL
Lateral flexion: When working unilaterally (only one side contracting) they laterally flex your spine, meaning you bend over to one side.
Extension: They can also extend the lumbar spin
Stabilization: They play a major role in stabilising the lower back, especially when seated.
It is important to stretch these muscles to alleviate an imbalance that can cause major low back pain.
