Arnold Schwarzenegger has been helping train his 28-year-old love child Joseph Baena for his son’s bodybuilding debut at a competition in Colorado this Saturday.

The 78-year-old former Governor of California and Hollywood action star has been hands on helping as Baena works out at Gold’s Gym in Venice, California, ahead of his first bodybuilding competition.

In videos posted on his TikTok, Baena shows off his muscle-building skills as he lifts weights while Schwarzenegger stands nearby watching his son follow in his own legendary footsteps. Arnold is a seven-time Mr. Olympia and one of the most famous bodybuilders in history.

“You have to shock the muscles,” Baena captioned one of the clips.

In another clip, Baena wrote “almost showtime” as he flexed and showed off his massive muscles for the hundreds of thousands of followers he’s amassed on his social media.

On March 18, the nepo-baby wrote that he had packed on 18 lbs in 8 weeks leading up to the big competition for his debut at NPC Natural Colorado State Championships which will be held at Pinnacle Performing Arts Center in Denver, on Saturday, TMZ reported.

Baena said he put on 18 lbs in 8 weeks ahead of the competition.

“Every athlete who enters this show will be drug tested,” a message on the competition event page read. There is no additional charge for testing. The testing process for this event may be inconvenient but well worth the extra effort to provide the same testing experience for each athlete.”

“By entering this event, each athlete agrees to schedule and take a 30 minute polygraph test prior to the competition at either the Colorado Springs or Denver testing locations to be announced.”

“Each athlete agrees to abide by the professional polygraph results and no refunds will be given for a positive test result,” it added.

Baena has been documenting his transformation for his hundreds of thousands of followers.

There has been speculation for years whether Arnold’s half-Guatemalan love child would indeed follow in his footsteps, but up until recently, those rumors were just that.

In 2011, Schwarzenegger revealed he fathered Baena after a “one-night stand” with his former housekeeper Mildred “Patty” Baena. The reveal ended Arnold’s 25 year marriage with Maria Shriver.

Of all five of Schwarzenegger’s kids, Baena has followed most closely after his father as an actor and bodybuilder. This despite the fact that he spent most of his childhood being raised by his mother and growing up in Bakersfield, CA, the Daily Mail reported.

“He’s an amazing father. He’s a great person to look up to and he’s the smartest man I know,” Baena told ET in 2023.

Baena will make his debut at the bodybuilding competition this Saturday.

“It’s been a great journey and he’s always been so supportive of whatever I do. So, I’m just really grateful to have a dad like him.”

Schwarzenegger has also been heading to the gym lately, as he’s reportedly getting ready to reclaim his role in the “Conan the Barbarian” sequel.

The action star has reportedly been “pushing himself to the limit” and is determined to return to peak physical shape as he reprises one of his most iconic roles in the long-awaited sequel, according to the National Enquirer.

The original movie was released in May 1982, with Schwarzenegger, then 34, playing the title character.

The movie was a huge success for the studio and the former bodybuilder as it grossed $79 million at the box office and launched the Austrian as a genuine Hollywood star. 

In 2011, Schwarzenegger revealed he fathered Baena after a “one-night stand” with a former housekeeper.

He also starred in the 1984 sequel, Conan the Destroyer, the same year he played Terminator.

The project, dubbed “King Conan,” has been in the works for decades. It will focus on an older version of the warrior who must fight once more.

The original was remade in 2011 starring Jason Momoa, but it was a box office flop.

The sequel will mark a triumphant return and perhaps finale to Schwarzenegger’s glittering film career.
