I will be the first to admit that it looks cool to get your foot behind your head or balance on your hands with your feet flying up behind you. I admire the shapes that flexible and strong students can make on their mats. But there is a limit to my marveling.

A Google search of the term "Online Yoga Class" will return a results list of about 8,220,000 results (probably more by the time you read this post). Of that data set there are about 2,710,000 results for videos.
