1. She Prioritizes Mental Health

Jennifer revealed she is a huge fan of therapy. "Therapy [is] a wonderful amount of just trying to understand it and also give examples of what I do not want to become. Watching behavior of what I will never become. Seeing people I love get lost, lose the plot. You can only help someone as much as they're willing to be helped,” she explained. "I do believe that at the core of everyone there is goodness. Watching people in my life go through hardships and just hold onto resentment and watching that eat them away. Forgiveness is not in their vocabulary. That's a real shame because I believe that that is really an important thing to be able to forgive people."

2. She Uses Sleep Apps

Jennifer revealed that good sleep is her secret to feeling her strongest. “That's when our cells are rejuvenating, right?” she said. One of the ways she gets her z’s? Sleep apps, revealing she uses five of them. “I have this little device just for sleep apps and meditations, and I've been trying to go to bed earlier. It's hard. The world shuts down, the phone stops ringing, and that's when I can have ‘me time.’ I can watch a show and just sort of putter.”

3. She Exhibits Serious Willpower

Sometimes Jennifer cheats when it comes to her diet, but she manages to limit herself to one morsel. “A chip. Crunch, crunch, crunch,” she joked when asked about her go-to stress-eating food. “Usually. I'm good at that. I can have one M&M, one chip. I know, that's so annoying.”

Jennifer tries to exercise daily. “I had an injury last fall and I was only able to do Pilates, which I absolutely love. But I was missing that kind of sweat when you just go for it,” she explained. “I'm going back to my 15-15-15, which is a 15-minute spin, elliptical, run. And then just old school: I can chase myself around a gym. I need some kind of movement, even if it's just 10 minutes a day on a trampoline.”

5. She Won’t Drink Sugary Drinks

Jennifer revealed that her go-to alcoholic beverage doesn’t have any added sugar in it. “A margarita — clean, no sugar — or a dirty martini,” she revealed. “I only have two to three drinks, tops, and I don't do exotic. When someone asks, ‘Would you like a cranberry-coconut-cucumber-spiced or hibiscus whatever?’ No, I would not. But when I moved into my house, a few people got me tequilas of the month as housewarming gifts. I have a cellar of all kinds of spirits — you could come here and probably order anything you wanted to.”

Jennifer Aniston is known for looking always put together on TV, but on Instagram she's not afraid to show a more vulnerable side of herself. Yesterday, she posted a picture of herself with wild hair and seemingly no makeup on, with the caption: "Okay, humidity." Despite the untamed locks, she looks fantastic. How does Aniston stay so fit?

“Variety is key” when it comes to Jen’s workouts. "Mixing it up is always fun because that way you know you're excited, and it's muscle confusion. It keeps your body awake," she told Women’s Health.

"It's the longest workout I've actually stayed with consistently other than yoga," she told InStyle. "There's something about the mental aspect of boxing — the drills, your brain has to work, you're not just sitting on a bike. It's amazing."
