The adductor pullback is a exercise designed by the postural restoration institute (PRI). The exercise is designed to get the client to shift into their left hip mimicking the qualities of left stance. Left stance is important due to the body's natural asymmetry that is present which creates a predictable set of compensation patterns. Often times you will find individuals with low back or hip pain who demonstrate lack of hip internal rotation on the left leg as opposed to the right leg. This exercise is one of the potential steps one could take to improve hip internal rotation specific to the left leg.
