What does the QL compensate for?

How do you release tight QL?

Apply direct pressure between all three points and just to the side of your spine. Do not get confused with the big muscles near your spine, as you want to target the soft tissue outside of those. Lean onto the ball and take 2-3 minutes to breathe, relax over the ball, and try not to tense up.
