1. Know Your Body

Jessica stresses the importance of understanding your body. "I'm aware of how my muscles feel, what it feels like when anything changes. Playing sports and being physical helps me maintain that sort of relationship with my own body. So when I'm doing something, or performing in a physical role, I understand that," she explained to ESPN.

2. Hit the Gym…But Not Alone

Jessica trains with celebrity body guru Ben Bruno and even does workouts with her husband, the perfect workout buddy. “Please excuse the photobomb from @justintimberlake while @jessicabiel casually knocks out a super-impressive set of single leg squats,” Bruno captioned one video of their workout. “We’ll give Justin a pass since he’s doing sled rows with four plates on the sled and making it look easy. They’ve definitely gotta be one of the fittest couples around, and they always work hard in the gym while also making sure to keep it fun. Very cool.” In another post she works out with Justin. “Swolemates,” she captioned it.

3. Do Yoga

"I started getting into yoga about 10 years ago through a close friend who was an instructor. At first I felt like, ‘I can’t do all those crazy poses,’ and I still can’t, but I’m not competing with anyone. I want to demystify yoga and bring it out to more women and men in the community, where it doesn’t have to be intimidating,” Jessica told Gaiam about her love of posing.

4. Approach Diet with Moderation

Jessica has a moderate approach to diet. "I'm not all-out anything," she confessed to Los Angeles Times. However, she does avoid a few types of food. "Honestly, I just feel better when I don't have gluten or wheat or dairy," she said. "My digestion is better, I feel better, I have more energy." She also detailed her diet to the publication. “We’ll start off with Paleo pancakes with some cashew or almond butter on top with some local honey, and we like chicken-apple sausage, and then maybe a fresh juice from the Juicero machine, which we love, we have some green tea with honey—that’s a pretty normal morning for me,” she said. Then, for lunch, she might eat a salad with greens from her garden with quinoa or a veggie burger from Whole Foods and nuts. One of her favorite snacks is gluten-free pretzels with dairy-free almond 'cheese' dip. “And then dinner, if we’re home, it would be cooking up some salmon, some rice, grilling some vegetables, or going out and having some chicken, something a little heartier for dinner,” she added

5. Take a Hike

Jessica is a big hiker. "I've learned that I can push forward, which was exciting for me,” she told Glamour about hiking Mount Kilimanjaro. “When you get out into the wilderness and strip [away] all of the stuff in your everyday life, you really gain a great respect for your own life, simply as it is. Needing things starts to feel like, Oh, I kind of have everything, don't I? It's pretty great."

“What better way to celebrate than by doing single leg squats into deficit lunges. That’s a real party if you ask me,” Bruno wrote about the exercise Jess can be seen doing in the clip. “I’ll tell you guys what it’s really like to train Jess. I’ll think up some obscenely hard exercise in hopes of actually challenging her and then show her one shaky demo (these are really hard!). She’ll then proceed to knock out 3-4 sets with better form than me while smiling and singing @justintimberlake new song. In between sets she’ll field questions from her kids or help them with their form if they’re working out with her, and then at the end when I tell her she did a good job, she’ll go ‘was that good?’ Like, she doesn’t even know that what she did was hard. Yes Jess, it’s VERY good. Show her some love on her special day because she’s a real badass.”

I want to demystify yoga and bring it out to more women and men in the community, where it doesn’t have to be intimidating,” Jessica told Gaiam. Here is why you should try yoga, says Harvard Health. “Researchers found that people who practiced yoga for at least 30 minutes once a week for at least four years, gained less weight during middle adulthood,” they said. “People who were overweight actually lost weight. Overall, those who practiced yoga had lower body mass indexes (BMIs) compared with those who did not practice yoga. Researchers attributed this to mindfulness. Mindful eating can lead to a more positive relationship with food and eating.”

"I've learned that I can push forward, which was exciting for me,” she told Glamour about the experience. “When you get out into the wilderness and strip [away] all of the stuff in your everyday life, you really gain a great respect for your own life, simply as it is. Needing things starts to feel like, Oh, I kind of have everything, don't I? It's pretty great.” The National Parks Service explains that the physical benefits of hiking include building stronger muscles and bones, improving your sense of balance, improving your heart health, and decreasing the risk of certain respiratory problems.
