Jennifer Aniston is seriously goals.
The 50-year-old is at the top of her game career-wise, is about to star in a hit new film The Morning Show, alongside Reese Witherspoon and Steve Carrell, she just joined Instagram a week ago and already has a cool 16 million followers, plus she manages to always look incredible.
So, how does she do it?
Well, Jen has just given her fans an insight into just how she maintains her insanely fit body - and we're not gonna lie, it's a lot of work.
While she sticks to a healthy diet, there's also a strict eating habit Jen adheres to that she credits for helping her look and feel her best.
"I do intermittent fasting, so there's no food in the morning," she told the UK's Radio Times this week.
"I noticed a big difference in going without solid food for 16 hours."
And she's also into a big wellness trend that's been going off this year - drinking celery juice.
"Today, I woke up and had a celery juice," she said.
"Then I started to brew some coffee, but I don't drink coffee that early."
Fans of celery juice say the drink aids digestion, but heath experts warn there is no scientific evidence to support the benefits of the trendy habit.
Jen works out most days of the week and does a mix of gym classes, weights and resistance exercises with her trainer, as well as cardio sessions.
"I go in and out of [certain exercises]. I do The Class by Taryn Toomey, and I'm back in the gym with my trainer, throwing heavy boulders around and pushing medicine balls and wiggling and shaking that big rope thing - battle ropes," she told Vogue in 2017.
"Yes! They're hard! But it's fun. I started doing that when I was filming We're the Millers and I really liked it. It kicks your butt, though, so I dip in and out of that throughout the year. And then I do 45 mins of intervals on my elliptical. I raise the incline, run for two mins, walk for one, run for two. . . and I do it for 20 minutes straight until I'm just drenched."
Jen's personal trainer Leyon Azubuike uses a training technique called "periodisation", which allows him to adjust workouts based on his client's schedule.
"Depending on where we are in that cycle dictates the duration and intensity of Jen's workout," Leyon told Women's Health.
"If I know Jen isn't filming anything, it's a different phase than if I know she has something coming up tomorrow. If she's going to be walking up to receive an award, I'm not going to destroy her legs in the gym the day before."
As for the types of exercises they do, it's all about getting fit and strong.
"We box, we jump rope, we do strength training, we do a lot of work with resistance bands ... we're big on resistance bands," says Leyon.
"We rotate these things so it's always hard, she's consistently being challenged. I'm a big fan of switching things up, so the body reacts in a positive way and changes.
"Every core exercise I throw at her, she dominates it. She can hold a two- or three-minute plank rather easily."
When it comes to diet, Leyon recommends "avocados, coconut oil, salmon, fish oil ... anything that's a good form of fat is great."

When you work out as much as Jen does, it's important to ensure your body has time to rest and recuperate after intense exercise.
"Of course I take days off. It's important to rest the body," Jen said.
And she's also not afraid to take long breaks.
"I can go a whole week saying, 'I'm not going to work out'. Your body will tell you what it needs," she said.
"It's hard work, you know. You work out, you just take care of yourself and you exercise."
But while she looks amazing, Jen says her main motivation for sticking to her strict regimen is because she always wants to feel her best.
"I feel really beautiful when I finish a great workout. You eat right, you sleep, you're happy," she said.
"Because I've taken care of my body, my endorphins are going, my blood is pumping. I'm taking care of the one body I have."
