What it is: A method that teaches awareness through attention to anatomical precision and alignment in poses. There’s an emphasis on healing the body and mind using postures. What to expect: Expect detailed instructions and to hold poses longer than in other styles. Beginner-level classes focus on standing poses. Most teachers use props as learning tools and offer restoratives classes. Founder/guru: B.K.S. Iyengar. B. 1918. "Yoga has to be done with the intellect of the head as well as the intellect of the heart." Why you want to try it: You’re a stickler for details, and the technical intricacies of anatomy help focus your attention so you can turn inward. You find it worth the effort to amass props and properly set up a pose so you can stay put and access yoga’s power to heal and transform. FYI: B.K.S. Iyengar’s book Light on Yoga, published in 1966, sparked the yoga revolution in the West. (Description borrowed from prana.com)
