In a recent Instagram the mother-of-two explains that she doesn’t show off her body for attention, but is simply proud of her transformation. “Because when I look at this photo, I see strength. If I’m honest, I lost a little too much weight after my divorce, and I would be lying if I said I didn’t enjoy the number I saw. But that’s an unhealthy way to look at it. It should never be about the number. It should be about how you feel,” she wrote. “I have been actively becoming strong again for me. I look at this pic now and I’m proud of myself for the hard work and commitment to loving myself. This body made two beautiful humans. I’m proud of my body. And it’s not just because I have new boobs, though yes they are two perks :) and since my breast augmentation I have felt more empowered about my decision. I’m proud that I have made choices for me. And I want to encourage you to do what makes you happy too… move the way you want to move… show off what you are proud of… feel your strength. And be proud of YOU, no matter what shape or size you are.”

Jana often shares her at-home workouts via her Instagram stories, which consist of a lot of cardio. However, she also works out with Nashville based personal trainer-to-the-stars Erin Oprea and even uses her Pretty Muscles app workouts. “I work out with Erin two times a week,” she explained in an Instagram story. The duo do “a ton of squats, sumo squats, lunges.”

3. Running Helped Her “Lean Out”

Jana is also a huge fan of running, after Oprea suggested she partake in the calorie-blasting cardio workout. “I hated running and now I love it,” she confessed. “It’s helped me lean out.”

4. Moderation Is Key

“I personally think everything in moderation,” Jana has said about her approach to diet. “I had a chocolate chip cookie last night. I will eat another one tonight. I don’t think you should deprive yourself of anything. I think, eat when you are hungry. But all-around diet is how I do it.”

5. She Works Out for the Mental Health Benefits As Well

In an Instagram story earlier this year, Jana explained that she works out even when she doesn’t feel like it because it ultimately makes her feel better. “Still not feeling 100 percent,” she explained. “But I'm still going to run it out, sweat it out." She previously explained to Us Weekly that exercise helps her keep sane. “Working out for me is my sanity…Even just going for a walk, that is a place where I come back and I'm like, 'I feel good, I feel balanced. Working out is 100% how I stay level."
