Arnold Schwarzenegger's documentary on Netflix is a must-watch if you're a fan of the actor. In "Arnold," we get the full scope of his life, including a bit about the son he had out of an extramarital affair, Joseph Baena. While they weren't as close in his youth, Baena has managed to grow closer with his father in recent years and even developed a bit of his father's gym habits after being overweight in high school.

Joseph Baena appeared as a guest on the "UNWAXED" podcast and was asked about when his whole fitness journey started. Baena confessed that while he may look like a living statue on his Instagram page, that took a lot of work that started all the way back in high school.
