This exercise comes from the postural restoration institute (PRI). Its purpose is to help restore neutrality in the body to help offset our asymmetrical tendencies. It can be a very useful tool for someone with low back pain, hip pain, shoulder pain to name a few. When performed correctly you should feel both hamstrings engage (left > right), a left adductor, your left abs, and a right glute muscle. Hold this position as you focus on proper breathing mechanics. If able, a balloon can be added to the exercise to ensure proper breathing mechanics are being utilized.
