Anthony Grim Hall (London): "I first started practicing yoga in 2007 as a way of dealing with the anger of having my house burgled. I was in my mid forties over weight and not very flexible. I learnt through Ashtanga books from the local Library, and later from videos. I started a blog in 2008, Krishnamacharya Ashtanga Vinyasa Krama yoga at home, to share my home practice. Over the years the blog has become more historical and particularly an investigation, both in theory and practice of Krishnamacharya’s teaching.
