If you notice Arnold does not keep in touch with bodybuilding anymore, he dosen't talk about contests today because he really has no idea. In the 90's he was alot more into it, probably because he had to commentate alot in the Arnold Classic on the athletes posing. He also was friends with Kevin Levrone, they even did a few pictures together on Arnold's film set.
He always had beef with Dorian though, saying that he never even attempted to promote the sport. In which Dorian responded 'Arnold dosent know anything about bodybuilding, he just turns up to the AC every year and lets everybody kiss his ass'. They are not friends lol.
I don't think he's a fan of the sport today at all
