Jessie, who didn’t start exercising until 2012, explains that fitness is good for your overall health – and is more about feeling good than looking it. “I found that my immune system was better and I wasn't getting sick, I looked better, my clothes fit better, my heart was better, my skin was better, and I just felt better,” she told Shape. “I attracted nicer people because I was nicer and happier, and more inspired. It really affects your mood. There are some grumpy people I just want to take to a fitness class, so they can shake out some of the sad sweat!"

2. She Maintains Variety with Her Workout

Jessie does a lot of different workouts depending on her mood. "If I move, it's good,” she told Shape. “Sometimes I just want to stretch, and I don't want to do any weights, or I just want to use my own bodyweight and do squats, lunges, or jump around, kind of getting to know my own body in some way. Other days, I do deadlifts and barbell squats, and I love sled pushes. I really feel the burn the next day. For cardio, I like rowing and cycling. But I can't run-I get bored."

Jessie sets herself up for workout success even when she is traveling. "I travel everywhere with a foam roller, plus protein water, my vegan protein powder, and a resistance band. Usually there's a gym everywhere I go, or I can just go work out outside. I think it's important to educate yourself on how you can work out without any machinery,” she told Shape.

4. She Maintains Flexibilty

"I'm quite flexible and I used to dance, so I like to make sure that I keep my flexibility. I think sometimes you can get so obsessed with fitness that you get stiff-I have really tight hip flexors. That's why I started doing aerial yoga recently,” Jessie told Shape.

5. She Is (Usually) Vegan

After experiencing fertility issues, Jessie switched to a plant-based diet. "So, four years ago, I cut out sugar from my diet to try and stop bacteria from building up in my body," she told Plant Based News in 2019. "Once I cut out sugar, I realized how much I began to enjoy food when it was good for me—and it was balancing out everything—my health, my moods, my sleep." While she has been mostly vegan ever since, during her pregnancy she has craved meat – and even shared a photo of chicken and potatoes.
