I started doing Yoga a few years ago. The reasons for that can be saved for another post, but as I progressed I found myself keeping an online log of what classes I watched on youtube. The googledoc I kept is available here if you are interested in checking it out.
I found myself constantly coming back to the online classes taught by Ester Ekhart. Her approach was simple, kind and thoughtful. I really could understand her cue’s and it helped me keep my mind focused on the pose and not wandering with a ton of useless thoughts.
If you are looking for an online Yoga school, I would highly recommend you checking out her site. http://www.ekhartyoga.com/
A beginners playlist is below if you are interested in trying it out for yourself.
