These two exercises can help to stabilize the hips and increase overall postural stability. The first exercise consists of lying in a hooklying position in a posterior pelvic tilt( low back against table), and then squeezing the ball a few times in a row and then relax.
The second exercise is for those with less pain as it is more challenging. This exercise consists of beginning in a posterior pelvic tilt and then lifting into a bridge. The exercise is completed by squeezing the ball a few times before resetting. Check them both out in the image below!
