So, you’ve been thinking for a while that you’d like to try out this yoga thing that everyone else seems to be doing and talking about. You’ve finally made your intention to give it a go: you go online to look for a class and.... whoa, hang on a minute, there are over ten different types of yoga to choose from here. Some of them have got funny Indian sounding names and you’ve no idea which one to choose or what you may be getting into. Will you be sat around burning incense and listening to Ravi Shankar or will you be locked in a heated room at 36 °C, being subjected to rigorous physical exercise?
