Yoga with props: Chair Backbend - Deep backbends can cause a tightening of the breath, and, if your upper back isn't open, your lower back and sacrum will take the brunt of your backbending. By working with props, you can get support to help you relax and fine-tune your breathing. This chair backbend isolates the upper back, which needs to be open for you to move into deeper backbends.
