Jennifer Aniston has long been our ultimate fitness North Star, but it turns out her toned physique isn’t just the result of “good genes”—it’s backed by serious science.
The Friends alum has been a vocal advocate for Pvolve, a functional fitness method she credits for keeping her strong and, more importantly, pain-free. Now, a groundbreaking new study is proving that Jen’s favorite sweat session is a literal fountain of youth for women navigating the challenges of menopause.
According to a study conducted by the University of Exeter and published in the Medicine & Science in Sports & Exercise journal, the Pvolve method is remarkably “effective at improving strength and balance in women during and post-menopause.”
The news has sent waves through TikTok and Instagram, where fitness enthusiasts are praising the -year-old actress for promoting a routine that “respects the body” rather than breaking it down.
“This study is the first time researchers have found the benefits of resistance exercise on lower limb strength and balance can be maintained throughout the menopause transition,” the University claimed.
The research followed healthy women—spanning pre-, peri-, and post-menopause—who weren’t on hormone replacement therapy. After just weeks of Pvolve’s low-impact resistance training, the results were staggering.
The participants saw a % increase in hip function and lower body strength, a % jump in full-body flexibility, and a % boost in balance and mobility. Perhaps most importantly for those looking to mirror Jen’s lean look, the women gained lean muscle without increasing their total body mass.
Aniston, who officially joined Pvolve as an ambassador in , originally discovered the brand through a friend.
“Not only did I notice her complete transformation—physically in her energy level—but she also explained that Pvolve is functional fitness that respects where your body is at,” Aniston shared at the time.
For The Morning Show star, the draw was the ability to work around persistent back pain and “current limitations” while still seeing major results. It’s a far cry from the “no pain, no gain” myths she has worked hard to debunk.
“I leave every workout feeling energized and strong, but not beat up,” she previously told CR Fashion Book. “I encourage people to try it and see it for themselves. Whatever your fitness level, it’s a workout where you can truly start where you are.”
Julie Cartwright, president of Pvolve, couldn’t be more thrilled about the clinical validation. “Women undergo tremendous physical change during the menopause transition,” she said. “This research shows that the Pvolve method can serve as an intervention, helping women to live better and feel better throughout their lives.”
As for Jen, she’s just happy to keep things fresh. “I don’t think I’ve had the same class twice,” she noted of the variety that keeps her coming back.
With science now confirming what Jen has known for years, it looks like the “Aniston Effect” is about to inspire a whole new generation of women to pick up the resistance bands. Strength, balance, and a Rachel Green glow? Sign us up!
