Thank you for your reply! I did watch the inro video, but still didn't understand how to search for the advanced videos within the same folders. Are they different level of difficulty or the videos are same levels within each folder? I also did not understand if "Light": videos in Tone folder means the length of the videos only or the difficulty. The clarification will be appreciated.
If there is a word or pdf document with the description of the categories (I do not have Instagram account, so I do not have access to the posts there) it will be very helpful.
Thank you for the help!
