As a Buzzador-tester, I got to try out Yoogaia. If you haven't heard it before, Yoogaia is a website where you can do live and recorded yoga inspired classes. It's global so sometimes your teacher is in Hong Kong or London or Helsinki. The instructors are for the most part really good and you can also leave your feedback after the class.
I have quite enjoyed this type of "group" class and there is a good variety of classes such as yoga for kids, chakra meditation, stretching etc. If you want to give it a go, you can try the site for 7 days for free. The best part is no card details is needed so you are not scammed into a membership you might not want.
All in all, I really recommend Yoogaia. Give it a try and see how you like it.
