In desperate need of a more exciting workout than slogging away at the gym, after seeing an advert on TV, I bought this and what a great buy! Not only does it have more exciting elements of yoga, which I love, but brings in basic boxing exercises which are great fun. As for the tension release of shouting back at the instructor - and who hasn't wanted to do that - what a great way to workout, have fun and feel so much happier and relaxed at the end. Certainly a recommended buy - just make sure you are on your own - the shouting takes some getting used to! Enjoy!
