Have you ever felt a nagging pull in your lower back when trying to do a forward fold in yoga? While lower back pain might have hundreds of probable causes, in yoga anatomy we know that the hinging action of the pelvis over the thighs is crucial when it comes to forward folding. If your pelvis is not able to roll over the femurs, the lower back gets locked in a posterior tuck, which ends up hindering the movement. This practice breaks down how to maintain the pelvis hinging over the thighs as you move through your yoga practice in different positions and relationship to gravity.
