Say hello to Arnold Schwarzenegger’s not-so-little kin. Indeed, the Terminator star’s youngest son Joseph Baena, 27, has detailed his rigorous fitness journey on social media. And now, he’s reflecting on the one sport that inspired him to focus on his health. “People sometimes forget that I used to be chubby in high school,” Joseph captioned his July 18 Instagram post, which sees him looking back on his weight loss over the years. “I got cut from my basketball and soccer team because I couldn’t keep up with the other kids. Swim didn’t have tryouts thankfully and completely changed my life forever.” According to the bodybuilder, this activity was his “introduction to fitness and training.” And while Joseph—whose mom is Mildred Baena—has tried out other high intensity sports in recent years, he’s grateful that he found swimming at a young age.
