Today's Throwback Thursday class is a definite crowdpleaser. But don't be fooled by the playful title – it gets to certain body parts that can often get lazy and you may well feel this one the following day! Being Esther, there is, of course, some spiritual challenge in there as well. Let us know how you get on!

A challenging yet grounding practice, this yoga sequence focuses on balance, stability, core, leg and glute strength, plus functional flexibility and whole body integration. You'll need a couple of blocks - but they're only used for a small part of the practice.
