Backbends require much courage as they open our hearts. The collarbones move away from each other drawing the shoulders back & the shoulder blades move down the back & into the body to scoop the chest forward & up. The legs extend, contracting the hamstrings & lengthening the quads without restricting the sacrum. Backbending postures are energising, they lift our spirits & counteract the hours we spend hunched over our desks!!
