Arnold Schwarzenegger's son shows off transformation after insane weight loss

The lithe physique of Christopher Schwarzenegger has been turning heads in West Hollywood.

Son of Conan the Barbarian himself, Arnold Schwarzenegger, and his ex-wife Maria Shriver, the 27-year-old was pictured parking outside the Restoration Hardware restaurant over the Easter weekend for a family meal.

He was also joined by brother Patrick (who played Saxon Ratliff in the third season of HBO sensation The White Lotus), sisters Christina and Katherine, the latter's husband and Jurassic World actor Chris Pratt, and mother Maria.

Christopher, who works at production company Indus Valley Media as its director of development, opted for a tight-fitted long-sleeve top and grey bottoms for the occasion.

This comes in the wake of his weight loss journey that began five years ago, which he reportedly undertook as a challenge to himself ahead of graduating from the University of Michigan.

"He started working out and making better food choices," a source to Hollywood Life revealed.

"He was away at school, living like a typical college kid for a few years, but he's growing up now and ready to take better care of himself."

Rumbles of a slimmer figure first emerged when Christopher was spotted at a gym in 2023, but it's unknown whether or not his famously buff father has ever provided health advice for him.

Around the same time, the 'Austrian Oak' published in his weekly newsletter The Pump Daily: "My advice to beginners is really simple: begin, and then don't stop until it is a routine.

"For a lot of people, that first step is the hardest. So find something, anything, you can do. Once you begin, the key is keeping your momentum. Motivation is fleeting, but routine is what carries you on.

"You need to make this a routine. Do whatever you can do every day for a month, and then build on that."

When Christopher turned 24 years of age in 2021, both Patrick and Arnold shared their pride over his dedication in the gym.

"Proud of you. New job. Crushing in the gym. Whole new person. Can't wait to see what this year brings," his brother wrote on Instagram.

Meanwhile, their bodybuilding father praised him, saying: "Between your boxing classes, your weightlifting classes, your stretching classes, your cycling classes, and on and on, I can't even keep up with you!"
