On Sunday, the Friends star posted a reverse video of herself emerging from the temperature-controlled waters in a black bathing suit, prompting the retrieval of her sunglasses, a cover-up, and an ice-cold beverage. "Oh so now I finally get what @missymisdemeanorelliott meant by put your thing down, flip it, and reverse it....only took me ten years," she captioned the sexy 'Gram. Many people were impressed by the actress's tech-savvy ability that made the video possible, while others (present party included) couldn't get over the fact that it appears as if Courteney — who just turned 55 years old last month — is aging backwards in the clip. "I don't know what's cooler, this video or how good your body looks," wrote Erin Foster. Meanwhile, Isla Fisher simply left several fire emojis in the comments section of the post.

Back in 2017, Courteney told New Beauty that she credited her killer body to Pilates and electrical stimulation workouts with her trainer, Foued Douma. "It builds and strengthens my muscles," she said, adding: "I also try to stretch and run once a week and play tennis on Sundays, which I love." For those who want to look like Courteney once they reach their 50s, she warns, "It’s good to start on your body when you’re 25 or 30, not 53. That’s the moral of the story."
