Still pictures of Arnold Swarzenegger posing with ballerinas

I am trying to figure out if Arnold Swarzenegger regularly did real ballet classes or just showed up at a ballet studio as part of a one time publicity stunt

And if he did normal ballet lessons for a man or just asked ballet instructors to teach him posing for an audience
