From Aniston’s low-impact 15-15-15 method to J.Lo’s dance-fueled circuit training, these stars prove that lasting fitness is all about consistency and self-care.
At 56, Jennifer Aniston continues to set trends—not just as a Hollywood icon but as a role model for living a healthy lifestyle.
She’s been vocal about the importance of working out daily and following a nutrition plan that makes her feel good. Among her daily habits, the Friends star includes meditation, staying hydrated, moving her body, and getting quality sleep.
But in an interview with InStyle magazine, Aniston said:
“I had an injury and could only do Pilates, which I love. But I missed the kind of sweat you get from a hard workout. So I’m going back to my 15-15-15 method—15 minutes on the treadmill, 15 minutes on the elliptical, and 15 minutes spinning. I need some kind of movement, even if it’s just 10 minutes on a trampoline.” inStyle magazine
This type of interval training isn’t exclusive to Aniston—it’s been around for a while and has gained popularity in recent decades.
Lauren Reid, a certified personal trainer in Orange County, California, and a Stride Xpro for Xponential, highlights the benefits of this method:
“This is a great way to minimize impact, challenge different muscle groups and keep your workout fresh so that you’re not burning out on 45 minutes of straight cardio using one modality,”
If you can’t commit to 45 minutes straight, you can do 15 minutes of high intensity, then complete the remaining 30 minutes later with lower intensity.
Another big plus: you can swap Aniston’s machines (elliptical, treadmill, bike) for other cardio options—jump rope, power walking, jogging, squats, or any aerobic exercise you enjoy.
Fitness trainer and journalist Lucy Gornall, who tried the method for 7 days, wrote in Hello Magazine:
“Doing just 15 minutes of three different workouts helped me avoid repetitive strain injuries—a common issue with runners.”
Bridie Wilkins, fitness editor at Women’s Health, also tried it and said:
“I realized I was so used to sets and reps in strength training that this flew by. It even felt meditative—just pedaling or putting one foot in front of the other.”
While this method tones and supports fat loss, trainers emphasizes that to build muscle definition, it should be paired with strength training.
And the best part? As long as you’re healthy and injury-free, there are no major contraindications.
Another Hollywood powerhouse known for her fitness dedication is Jennifer Lopez. At 55, she maintains a sculpted figure with a highly disciplined approach.
