We all know the type. The one who likes to tell you what time they go up to practice, how long they practice for, and how far their practice has 'progressed'. The ones who tell you that yoga has changed their life and it can change your life as well, hell, it probably should change your life, because if you're not doing yoga all the time then surely something is wrong. Whether you're getting these messages from that ever so loud and proud person in the changing room or from the onslaught of social media challenges and Insta-worthy pics, it's not that difficult to be cornered by a spiritual snob, or - gasp - turn into one.
