Arnold Schwarzenegger's son Joseph Baena labeled 'Arnold 2.0' in shirtless bodybuilding snap

Joseph Baena is definitely taking after his famous father, Arnold Schwarzenegger.

The recent graduate of Pepperdine University has been following in his father's footsteps in recent years as he's gotten more and more into bodybuilding, putting in hours at the gym and bulking up his frame. In an Instagram snap shared to his page this week, it's undeniable that he's channeling his dad.

Baena, 22, flexes his muscles in the photo, echoing his former Mr. Universe father's iconic poses from his days as a professional bodybuilder in the 1970s.

Fans labeled him "Arnold 2.0" in the comments section of the post, praising the "serious gains" that he's made in the gym.

"Starting to look like your father!" another commenter said.

During a recent interview with Us Weekly at the 13th Annual GO Gala, Baena said that he finds motivation in his father and the other people that he often works out with.

"Him, his friends, many, many other fellow gym mates," he said. "My father's a huge inspiration to me."

He also shared some advice that he got from the "Terminator" actor.

"To push it all the way and more weight. Push it more," he said. "I would say, you can always do more than you think you can."

The father-son duo is also known to frequent the gym together. Back in July, Schwarzenegger hit the gym with Baena on his 72nd birthday.

"BIG happy birthday to the best training partner in the world! Love you dad," Baena captioned a photo of himself with his father at the famous Venice Beach Gold's Gym location that Schwarzenegger was known to frequent during his bodybuilding career.

Schwarzenegger shares Baena with Mildred Baena, his former housekeeper with whom he had an affair during his marriage to Maria Shriver. Baena was born in October 1997, and Schwarzenegger split from Shriver in May 2011. They also share daughters Katherine, 29, and Christina 28, and sons Patrick, 26, and Christopher, 22.
