Like father, like son. Except not quite as thicc.

Arnold Schwarzenegger's son, Joseph Baena, is apparently taking after his father in the bodybuilding department. In a recent Instagram photo, the 21-year-old struck the same legendary pose his father made famous back in the '70s, showing off his lats and biceps.

"Just a lil thicc," Baena wrote in the caption.

Hey, we get it—not all of us can be former Mr. Universes and seven-time winners of Mr. Olympia. Here's the iconic pose in a photo from 1976:

We know the Austrian Oak is proud of his son's progress in the gym. In a birthday message in October of 2017, Schwarzenegger called Baena "a fantastic son and great training partner."

"You get stronger and smarter every year and I'm so proud of you," he said.
