Arnold Schwarzenegger's son Joseph Baena cracks top five in pro bodybuilding debut

Baena took fifth in the classic physique class at the INBA PNBA Pro/AM World Cup, held Saturday in California. In a video posted to Instagram, he said cracking the top five had been the goal and he was pleased to hit it. "I'm extremely proud of myself," he said. "It was an incredible experience for my first show as a pro."

The 29-year-old only started competing this year, and the World Cup was just his third show. He is the son of Schwarzenegger and Mildred Baena, and commenters beneath his posing routine video drew the obvious line to his father, writing "Like father, like son."

That comparison has some weight behind it. Schwarzenegger won Mr. Universe five times across competitions in the 1960s and 1970s, then helped push bodybuilding into the mainstream with the 1977 docudrama Pumping Iron and Hollywood muscle roles in Conan the Barbarian and the Terminator franchise.

Baena told GQ earlier this year that his father is "the best training partner," keeping him from slacking off in the gym, and that Schwarzenegger handed him "the bodybuilding encyclopedia" during college — the spark for his interest in the sport. Reflecting on the weekend, Baena said bodybuilding comes down to personal discipline but he leans on a wide circle of support. "My father always says there's no such thing as a 'self-made man,'" he said. "I have people in my corner."
