JENNIFER ANISTON IS starring in a new movie alongside Adam Sandler called Murder Mystery 2 that looks so, so good. Naturally, Aniston was at a photocall to promote the movie, and she brought her sculpted arms out to play.

It was clear from the photos that the 54-year-old star is jacked right now. Like, someone has clearly not been skipping arm day at the gym. Sure, Aniston has always been strong, but wow are her biceps sculpted these days.

Okay, but back to her fitness routine. To work her core muscles, Aniston likes to do V-ups and use an ab wheel to build strength. "We’ll use a sit-up to shock the body occasionally, but it’s not a major part of our core regimen,” Azubuike said.

Aniston is also happy to have guests join her during her workouts—she recently shared a sweet Instagram Story that showed her doing exercises at home while her dogs kinda-totally got in the way. Jen tried to do bicycle crunches and kettlebell squats as her pups did whatever the heck they wanted—as long as they were right on top of her.
