YouTube exercise videos are “inspiring” for multiple reasons, in comparison to using a written list of exercises. In particular, however, to see the “instructor” execute the exercises in real time with you shows to you the possibility of completing the exercise and creates a sort of social pressure to do the same… even if, of course, the instructor can’t see you. I think this experience most closely aligns with the “admiration of skill” elevation from an external source, from the types we discussed in class.
