Like father, like son! Joseph Baena, 22, is the spitting image of his famous father, Arnold Schwarzenegger, in a new photo the bodybuilder posted to Instagram. Joseph paused a weight-lifting session at the gym on September 23 to flex and strike a pose that looked awfully familiar. As Arnold’s oldest fans know, that was one of his go-to poses during his own bodybuilding days in the 1970s.
