Arnold Schwarzenegger has clearly taught his love child, Joseph Baena, the tricks of the trade as he triumphed in a bodybuilding competition this weekend.
Baena, 28, followed in his famous father's footsteps as he made his bodybuilding debut at the NPC Natural Colorado State competition, which was held at Pinnacle Performing Arts Center in Denver, CO, on Saturday.
And Baena beat out his competitors to claim a trio of titles in the Men's Open Bodybuilding Heavy Weight Class, Men's Classic Physique True Novice, and Men's Classic Physique Novice.
He also clinched silver in the Men's Classic Physique Open Class C, undoubtedly making his former Mr. Olympia father proud.
Baena's success came just days after he was seen pumping iron with Schwarzenegger, 78, in the gym.
The former Governor of California was seen helping his son perfect one of the signature moves from his heyday.
They perfected each shape as they attracted a crowd at Gold's Gym in Venice, California.
Schwarzenegger enjoyed an illustrious career as a competitive bodybuilder, winning seven Mr. Olympia titles before becoming Hollywood royalty and eventually turning to politics.
Out of all five of Schwarzenegger's children, Baena has followed in his footsteps the most, despite primarily growing up with his housekeeper mother, Mildred 'Patty' Baena, in Bakersfield, CA.
The Pepperdine University grad was only 13 in 2011 when Arnold revealed he secretly fathered him during a 'one-night stand' with his former housekeeper, which ended his 25-year marriage to journalist Maria Shriver. Their divorce was finalized in 2021.
Last year, Maria admitted in her poetry book I Am Maria that the divorce 'broke my heart, it broke my spirit, it broke what was left of me.'
'Without my marriage, my parents, a job, the dam of my lifelong capital-D Denial just blew apart.'
Schwarzenegger was seen teaching the 28-year-old his moves earlier in the week.
Of the former Mr. Olympia's five children, Baena shares his bodybuilding passion the most.
Baena was only 13 in 2011 when Arnold revealed he secretly fathered him.
Joseph and the FUBAR producer-star first bonded over fitness, and he gifted him a copy of The Encyclopedia of Modern Bodybuilding, which he co-authored in 1985.
'My dad is old-school; he doesn't believe in handouts. He believes hard work pays off, and so do I,' the Dog Patrol: Operation Santa Paws actor told Men's Health in 2022.
'I love the word honour, and I'm very prideful in the sense that if I use my dad's contacts or ask him for favours, I wonder what honour is that gonna bring me?'
Arnold has five children: Katherine, Christina, Patrick, and Christopher with his ex-wife Maria Shriver; Joseph with Mildred.
