Imagine if Arnold was your dad and you could could hit the gym with him!

Well, 18-year-old Joseph Baena knows exactly what that feels like as you'll see from TMZ's pic above!

It seems 68-year-old Arnold wants his son to start getting in the habit of pumping iron, and I guess you couldn't ask for a better spotter.

A New Mr Olympia or Mr Universe? 

The pair were snapped in the famous Gold's Gym in Venice and there's no question Joseph and his long locks slightly resemble his father in Conan the Barbarian and Pumping Iron.

And if young Joseph keeps it up - he'll certainly keep looking terrific!

Here's a recent shot of his body:

 

Hopefully they continue training together, so we can watch young Joseph start to resemble his famous father even more!
