Lying Piriformis Stretch

The lying piriformis is the gentlest of the four core piriformis stretches because it loads the muscle in a passive cross-body rotation without compressing the back of the hip joint. It is the right choice for people who get sciatic-like symptoms from deeper stretches like pigeon or supine figure-4. The cross-body position also produces a useful side effect: it lengthens the QL on the same side, addressing the lumbar component of piriformis-related pain.
