Arnold Schwarzenegger worked it out with the son who has become his spitting image.
Arnold showed Joseph Baena the ropes Saturday at Gold's Gym in Venice. The 18-year-old is jacked like an up-and-coming Mr. Universe, but the Pepperdine business major has other aspirations.
Arnold was bragging in the gym ... Joseph's pulling straight A's.
We haven't seen a single pic of the Arnold and Joseph together since he was a small boy, although we know the 2 were always in contact.
This kid could end up being the true Arnold protege.
Arnold was Mr. Dad Saturday, traveling to Coachella to spend time with son Patrick.
