Arnold Schwarzenegger’s son Chris looks unrecognizable years after dramatic weight loss

Arnold Schwarzenegger’s youngest son Christopher turned heads with his impressive transformation in a new family photo — and he didn’t need to flex to make a statement.

While big brother Patrick, 31, has been flaunting his physique on The White Lotus, Christopher, 27, let his progress do the talking in a snap shared by sister Katherine Schwarzenegger, 35, on Instagram Thursday in honor of National Sibling Day.

Also pictured was sister Christina, 33.
