HOW: Grab the top of your ankle on the side you plan to stretch with the other arm that is free with the palm facing the ceiling. Try to pull your knee back as tolerated to help increase the stretch of the hip flexors. Perform a posterior pelvic tilt (decrease the arch in your low back) and then rotate your chest towards the ceiling.
FEEL: You will feel a stretch in the back of the hip towards the ceiling, the front of the thigh of the leg on the floor, and your mid-back.
COMPENSATION: Keep your top leg's knee on the ground as you attempt to open your chest.
