It's a magic pose that targets many stretches at once: it unlocks tight hips, IT band, hamstrings, iliopsoas, quads, releases sciatica and lower back tension.
The muscles on the front are the iliopsoas and the muscles on the back are the six outward rotators.
It supplies branches to the iliopsoas  (designated by Girard, the iliacomuscular nerves).
It runs ventrally and backward, at first between the psoas major and minor, then crosses the deep face of the tendon of the latter and descends under cover of the sartorious over the terminal part of the iliopsoas.
An internal snapping hip is caused by the iliopsoas tendon as it catches on the front of the pelvis.
