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.

Dressed casually in a fitted navy tee and gray shorts, the once reclusive Schwarzenegger sibling looked fit, confident, and nearly unrecognizable from his former heavier-set appearance.

His latest look is the result of a quiet fitness journey he began back in 2020.

And it seems he may be taking notes from his gym-obsessed half-brother Joseph Baena, 25, Arnold’s son with the family’s former housekeeper Mildred Baena.
