I thought this product was a waste of time and money. It is a very amateur interview by someone who knows next to nothing about what he's talking about. The yoga teacher he "interviewed" was at least qualified and there was a demonstration that might be of some use to older beginners. However there was only about thirty seconds at the end discussing the history of yoga. To make it even worse, there were a couple of music interludes by a young woman who must be related to the producer.
