the Retreat program is very good, but two things could be improved: (1) even if there are 3 levels for each Yoga class, some positions (e.g. headstand) even at level one are very difficult to do for someone that has never practiced it before. A set of tips or additional videos/suggestions on how to execute or substitute particularly difficult poses would be helpful for beginners (2) the meditation videos are different from what I expected. I expected more guided meditation sessions, rather than explanations. So maybe it could be good to include more guided meditation material, or clarify this better in the product description.
