This is a shout-out to Pranamaya, who produce and distribute high quality yoga DVD’s ( Paul Grilley, Sarah Powers, and Jill Miller’s among others) and are now offering online courses. http://www.pranamaya.com/online-courses
You go to the website, create an account, and buy a class or workshop from the instructor of your choice. You can instantly stream the video you have purchased. And it goes into your account so you can log in anytime and stream any of your courses an unlimited number of times. Anywhere you have an internet connection, you have an instructor at your disposal. Right now the offerings are limited as they test market the idea. But, I think demand will be high and more courses will be available soon (please! please!) Delivery is instant, the media production values are high, and Pranamaya can, no doubt, produce these courses much faster and release them more frequently then a fully-packaged DVD. Instructors can also target specific topics (like the shoulder stand workshop being offered by Grilley) without having to produce a full DVD around them. And you don’t have to pack DVD’s when you travel. Instead, you just connect to the internet and an online yoga library awaits!
