Might be reaching here so correct me if I'm wrong but maybe that's her performative anorexia showing. Yin yoga is not intensive at all, especially for the 10 min she does. I know someone who exclusively walks/ runs to burn the calories.I doubt she even burns that many calories from the exercise she does, none of them are very intense.
Edit: NM, there she goes skipping through the fields. When her dad tracks her I wonder if he sees her going in circles/ staying on the spot and goes "oh lord another speech about being present and magical.."
