Stand tall and keep the core engaged as you begin by bringing the knee towards the chest. Open the hip, then add rotation as you pull the heel back behind and the knee through to center line. Exhale as you return the knee to chest. Pause, then reverse the movement, pulling the heel back towards the glute, opening the hip, sweeping the knee back to the chest, then relax. Repeat on the other side. Use a sturdy object (chair, rack, wall, etc) to hold onto if needed to assist in this movement. Make sure to remain standing tall and keep the core engaged through the movement, so that your hips remained square and you are able to move through your current range of motion. Should you feel pain, back out of this position and try a smaller range that is comfortable.
