Arnold Schwarzenegger celebrated his 79th birthday on Thursday by sharing photos of himself lifting weights, showing off his muscular arms in what appeared to be Los Angeles. The actor and former California governor wore a black T-shirt, matching shorts, sunglasses, and a gold watch while turning his birthday post into a full-on fitness statement. Schwarzenegger used the Instagram upload to promote Pump Club, his fitness community app featuring workout plans, nutrition tracking, and other training tools. “I don’t want any gifts,” Schwarzenegger wrote in the caption, directing followers toward his plan to shake up the fitness business instead. Still Serving Mr. Olympia Energy The comments section quickly became a tribute wall for Schwarzenegger’s physique and decades-long influence. Followers praised the seven-time Mr. Olympia winner for continuing to train nearly 50 years after his bodybuilding peak, with one commenter calling his physique among the best “for his age.” Schwarzenegger’s family and personal life also remain part of the broader fitness conversation: his 28-year-old son, Joseph Baena , is pursuing bodybuilding, while Schwarzenegger has been dating physical therapist Heather Milligan , 51, for 14 years. The couple made a rare public appearance together in Vienna in June at the Austrian World Summit, where they were photographed alongside Kamala Harris and Austrian President Alexander Van der Bellen. The birthday post lands after a career built on muscle, movie-star mythology, and public reinvention. Schwarzenegger has also acknowledged struggling with body image as he gets older, making the latest gym photos less about pretending time stopped and more about showing up anyway.
