It's good that he was able to get back into shape for the role. He had allowed himself to get kinda flabby when he was the governor of California, and it is usually a lot harder for us older guys to lose he pounds and pack on the muscle than it is for younger people.
Now I have not been following the thread very much so I'm a little out of the loop. What exactly is the plot of the Terminator film going to be? And what is Arnie's role in it? Is he playing a T800 model 101 yet again? Or is he playing one of the scientists who created Skynet and is the person that the 101 series is modeled after? Or is it some other plot that kinda comes out of left field that no one expected?
