Christopher Schwarzenegger is giving his half-brother Joseph Baena a run for his money when it comes to their biceps. The 28-year-old son of Arnold Schwarzenegger and Maria Shriver has been on a weight-loss journey for years, but he didn't just lose weight; he's put on a ton of muscle. This week, his biceps were on display at a pumpkin patch.

Christopher joined his sister Katherine Schwarzenegger, brother-in-law Chris Pratt, and their kids at a Brentwood pumpkin patch where they picked out the perfect gourds.

He proved he has not been missing arm day, carrying and balancing three pumpkins he deemed worthy for spooky season.

At one point, he drank a protein shake, making sure he hit his macros for the day.

After their day of fun, Katherine shared a post to start the countdown to Halloween. "Getting into the spooky spirit," she captioned the gallery.

The first slide was the mom of three covered in spooky stickers, and the second was from their day at the patch with her daughters, Lyla Maria and Eloise Christina, happily picking their pumpkins.  "Pumpkin patches, sticker jeans, and some littles who take Halloween very seriously. Countdown to candy starts… now," she continued.

Christopher's public outings were very rare until the last few years. He's been making appearances on his family's social media pages, appears to have a girlfriend, and seems to just be spending more time outside, receptive to paparazzi photos and general discourse about him. 

It all seems to be linked to his weight loss, with the young celebrity kid feeling confident. In May, Christopher opened up about his weight loss, saying, “I just saw how much my weight was prohibiting me from doing the everyday activities," like the ability to go skydiving. 

There has been speculation that he used weight loss drugs like Ozempic, but he has not openly said he's used it, crediting cutting out bread during Lent as one of the reasons he lost 30 pounds in two months.

His famous dad has also opened up about how difficult it was to navigate his son's weight when he was growing up.  He told The Times in June, “I could never go and say to him, ‘You’re overweight.'"

He explained that they introduced healthy foods to Christopher and the notion to "always go to the gym and all of that kind of stuff," but said it was a decision he had to make on his own later in life. 

“And then, out of nowhere, he decided that he wanted to be lean. And now he is,” the 77-year-old said. “So that is, of course, fantastic, the self-discipline and the self-motivation. I always felt one day it would have to come from him - and it did.”
