I’ve struggled for literal years with a restricted QL which I think stems from a bad ankle sprain I sustained back in 2015 that was never properly rehabbed. The end result was that I found that I was putting most of my weight on my left leg, while my right foot popped out to the side as a kickstand. Anyway, it’s something I’ve really been working on and I know I’m not alone in this. A tight QL can be caused by any number of reasons - like sitting cross-legged, for example, but to release it, all you really need is a ball.
