I like to do wheel because not only is it a backbend, it opens and balances all my chakras.
It is a heart opener, because ideally the apex of the pose expands the chest area and directs prana into the heart.
It improves my posture because it pulls my shoulders back, opens the groin area and articulates the spine.
It is an energy intensive posture that by its very effortful nature makes me deepen my breathing.
And because I can’t possibly focus on anything else while I am performing wheel, it draws my awareness inward, allowing me to reconnect to my deepest self.
