Baena is the son of Schwarzenegger and Mildred Baena. Over the years, Joseph has shared his interest in bodybuilding and acting, a decision that pulls him closer to his father. 

In the case of Christopher, his story is the opposite, with him having no interest in pursuing a public life. Over the past months, Christopher has undergone an impressive weight loss journey, losing weight and putting on muscle. His progress has led him to look very similar to Baena, with both having a striking similarity to their father.

In a photo shared by his elder sister Katherine, Christopher is seen with a mustache and wearing an all brown outfit. His smile and presence are similar to Beana's most recent photo, grabbed from a recent photo dump where he posted various images of himself on the beach.  

Both men are showcasing similar hairstyles and beards, showcasing the trademark Schwarzenegger bulk.

Christopher's physical transformation

Christopher has recently begun to appear more on his family's social media and on public outings, showcasing his weight loss journey. He's opened up about his experience earlier this year, revealing that his weight used to keep him from doing various activities. 

“I just saw how much my weight was prohibiting me from doing the everyday activities," he said, referring to adventuresl ike skydiving and the light. 

He shared that he lost 30 pounds within two months, with dropping bread during Lent as one of the methods he followed for losing weight.

Arnold Schwarzenegger also addressed his son's weight in an interview over the summer. “I could never go and say to him, ‘You’re overweight,'" he said to The Times.

Schwarzenegger shared that he and his family tried to get Christopher to eat healthy foods and to enjoy going to the gym, but that, in the end, Christopher had to make that decision for himself, which is what he ended up doing.  “And then, out of nowhere, he decided that he wanted to be lean. And now he is,” said Schwarzenegger. 

“So that is, of course, fantastic, the self-discipline and the self-motivation. I always felt one day it would have to come from him - and it did.”
