Robert F. Kennedy Jr., or RFK Jr., has the Terminator, Arnold Schwarzenegger, as his newest gym partner. Notably, the Secretary of Health and Human Services and the former governor of California go way back. Kennedy shared a delightful gym selfie with Schwarzenegger, trading Kid Rock for the Terminator star as his new workout partner.
RFK Jr brings in the Terminator, Arnold Schwarzenegger as his new gym partner
Robert F. Kennedy Jr. shared a sweet and wholesome selfie with the Terminator star Arnold Schwarzenegger. Kennedy shared a picture of the duo together, smiling, on his X (formerly Twitter) account. He cheekily wrote in the caption, “Senior’s Day, Gold’s Gym in Venice.” Unsurprisingly, the post garnered 68K likes, 3.7K reposts, 1.4K comments, and 922 bookmarks at the time of writing.
RFK Jr. and Schwarzenegger have known each other for a long time and were once even related by marriage. The Commando star was previously married to journalist Maria Shriver, the first cousin of RFK Jr., from 1986 to 2021. Kennedy even penned a wholesome piece about Schwarzenegger for the 2007 edition of Time 100 (via Entertainment Weekly).
He lavished praise on the Terminator star, calling him “a national leader for his efforts to restore Theodore Roosevelt’s conservation tradition to the G.O.P.” Furthermore, he wrote, “Schwarzenegger believes that good economic policy, over the long term, is always the same as good environmental policy.”
Schwarzenegger returned the favor and praised RFK Jr. in June 2025. The Predator star credited his former brother-in-law with helping him build his political career outside Hollywood. The 78-year-old said of Kennedy, “No matter if I believe in everything that he does or not, I will always support him.”
Schwarzenegger is known for his incredible fitness and is even helping his son, Joseph Baena, in his own bodybuilding career. Baena gushed over his father in an interview with GQ in April. He shared, “He’s the best training partner. I don’t know what to say. He pushes me. He makes sure that I don’t slack off in the gym. When the carbs are low and the calories are low and I start getting tired, he pumps me up.”
