Begin by standing in Tadasana (mountain pose) fold over, with slightly bent knees into Uttanasana (standing forward fold), then bend your right knee and place your right hand on the ground, a block, a stack of books, or your left ankle. Twist to your left and straighten your left leg and reach left arm high into the sky. Hold Parivritta Uttanasana (revolved forward fold) for several breaths and repeat on the other side.
Easy standing hip stretch or Parivrtta Uttanasana
For those of you that appreciate anatomy; this asana (pose) stretches the piriformis (which is often responsible for sciatic pain), the IT band, and other surrounding gluteal muscles.
Breath-Stretch-Enjoy!
