Static stretching doesn't release your tight psoas for two reasons: it triggers your stretch reflex (myotatic reflex), making your muscles tighter, and it doesn't change the messages that your nervous system is sending to your muscles to stay tight.

The psoas is a deep core muscle that does five different actions. So when your psoas is chronically tight, it can cause or contribute to many different painful conditions, like lower back pain, functional leg length discrepancy, idiopathic scoliosis, snapping hip syndrome, and more.
