Christopher Schwarzenegger turned heads once again, flaunting his fit new frame while vacationing with his famous family.

After his older brother Patrick, 31, captured attention with his shirtless scenes on The White Lotus, Christopher, 27, made his mark—donning a fitted short-sleeve shirt and shorts that highlighted his impressive transformation.

The eye-catching snap was shared by sister Katherine Schwarzenegger on Instagram Saturday, giving fans a peek at the fun-filled family boat trip.

It was a star-studded outing, with Katherine’s husband Chris Pratt and matriarch Maria Shriver also aboard. 

The Guardians of the Galaxy actor wasn’t shy either, showing off his ripped physique in swim shorts in the cheerful carousel.

For Christopher, the formerly private Schwarzenegger sibling is now nearly unrecognizable from his previously heavier-set self, as he progresses on the fitness journey he began in 2020.

Earlier this year, Christopher shared how his transformation began, revealing that eliminating a particular food from his diet helped him lose 30 pounds in just under two months.

Christopher mentioned that achieving his current shape took more than five years and involved experimentation before finding his ideal routine, which he discussed at the Inaugural Beacher Vitality Happy & Healthy Summit in Los Angeles in June.

The University of Michigan alumnus explained to Kelly Osbourne and the event’s host, Jeff Beacher, that during a trip to Australia in 2019, he faced a pivotal moment when he couldn’t skydive due to his weight, according to People.

‘I made it a big [deal] like, “Oh, I’m going to go out and do all this stuff, be in Australia,” and I just saw how much my weight was prohibiting me from doing the everyday activities.’

‘I was like, “I want to go skydiving.” And my friends were like, “Yeah, no shot.” I was like, “Yeah, I can’t skydive.”‘

Christopher traced his weight struggles back to high school, recalling bringing special healthy lunches to school.

‘I tried everything. I was doing meal delivery things in high school, and I remember feeling like a weirdo when I was bringing weird lunches to school.’

He admitted weight loss is ‘not an overnight thing’ and that it ‘took a lot of trial and error.’

‘And even still to this day … when you’re saying, oh, before and after photos … I don’t feel like I’m an after yet. I don’t feel like I’m at the point.’

Christopher also credited giving up bread for Lent with helping him lose 30 pounds.

‘Weirdly enough, I gave up bread for Lent. I don’t know if anyone’s Catholic in here, but I gave up bread for Lent.’

‘I was like, “Well, if I’m giving up bread, I might as well just take the opportunity and I’m a good Catholic boy, so I’m not going to break it,”‘ he stated.

Christopher looked trimmer than ever as he stepped out 

Meanwhile their half -brother Joseph Baena was iced out once again as he posed with dad Arnold

‘And that was my one rule. I was like, “I’m not going to break Lent.” And so I lost 30 pounds just through that.’

Although Christopher has mostly kept quiet about his fitness journey, a now-deleted 2021 Instagram post showed his brother Patrick, 31, praising his workout dedication.

In the post, The White Lotus star wrote, ‘Proud of you. New job. Crushing in the gym. Whole new person. Can’t wait to see what this year brings.’

His father Arnold also praised him.

‘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!’ the famous bodybuilder raved on Instagram. 

Christopher recently turned heads on Easter Sunday, showing off his fit new frame while celebrating the holiday with his famous family.

While big brother Patrick has been lighting up screens with his shirtless scenes on The White Lotus, Christopher made his own statement—sporting a snug long-sleeve and fitted grey slacks that highlighted his toned transformation.

The sighting comes just days after he proudly posed with his siblings in an Instagram tribute for National Sibling Day—looking noticeably trim in a rare family photo.

Back in 2020, a source told HollywoodLife that Christopher had made it a personal mission to ‘get healthy for graduation’ from the University of Michigan, a goal he ‘stuck to.’

‘He started working out and making better food choices. 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,’ the insider shared.

Instead of chasing quick fixes or trendy crash diets, Christopher reportedly cut back on junk food and committed to a consistent workout routine.

It was all reportedly part of an effort to mirror his father’s famously disciplined approach to fitness.

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

The action legend kept his relationship with Mildred hidden for years—until 2010, when news broke that they’d had a son together, Joseph, sending his marriage to Maria into a tailspin.
