Something wrong with that picture? I never seen Arnold so shitty! If it is photoshop word, I darte say it is the best photoshop so far out here (I have to work with photo and fH and flash everyday)!!!
Mid-late 70s, after he retired and prior to Conan, he went off hormones and serious training and adopted the tennis player look, just as Levrone did. Makes one wonder how much of him was real.

In both cases, done to look more acceptable for acting gigs.
