Arnold Schwarzenegger is known for his former bodybuilding competitions and muscled body, and it seems that his children have also inherited that passion.
In a new picture shared by Arnold's daughter Katherine, his son Christopher has unveiled a toned new look, completely unrecognizable from his former appearance in 2018 and 2019.
"My favorites forever and always #nationalsiblingday," Katherine captioned the post which showed Christopher in fitted navy tee and gray shorts, with a big smile on his face as the rarely-seen 27-year-old posed with his siblings, Katherine, Patrick and Christina.

Christopher's fitness journey is thought to have begun in 2020 when he made it a personal mission to get healthy ahead of his graduation from the University of Michigan.
He changed his approach to his diet, incorporating more proteins and healthy snacks and cutting back on sugar, and committed to a workout routine that would help him to lose fat and build strength.

Christopher has remained out of the spotlight, and keeps his social media accounts private. It is thought he is the Director of Development at Indus Valley Media, a Los Angeles-based production company servicing the global film and television marketplace.

The actor mostly eats a plant-based diet these days, and had switched from lifting free weights to focusing on biking, swimming and resistance training.

"First of all, I want you to know I’m doing great! I had my surgery on Monday, and by Friday, I was already at a big environmental event with my friend and fellow fitness crusader Jane Fonda," he continued. "Nobody would ever have thought I started the week with a surgery."
"I want to thank my whole team at the Cleveland Clinic. All of the doctors and nurses took amazing care of me and made the surgery as painless as possible," he added.
