Jena is a fan of a popular workout method. “My favorite type of workout is F45,” she told FOX. “It’s just a 45-minute class. And I think I like it so much because they play amazing music and it’s so loud.”

2. Weight Lifting

“I’m not a calm, soothing Pilates, yoga princess. I’m like, ‘Scream at me.’ I want to be dripping sweat,” continued Sims. “I want loud music, heavy weights. For my body type, I like to lift weights because I don’t need to do a lot of cardio. I find that lifting weights has been the most beneficial,” she told Fox. “I've been working on just upping my weights a little bit,” she added to Daily Mail. “I can get into this sweet spot and get kind of in a plateau of working out, so I upped my weights after seeing her video because I was so impressed by what she did with her fitness. I'm trying to lift heavier. Trying to build a booty.”

3. Clean Eating

To get in shape for her Sports Illustrated photoshoot, Jena didn’t diet, “ all I'm doing is just eating as clean as I can, but I'm still splurging,” she told Daily Mail. “Like, I had four dinner rolls last night at this charity event as well as my meal.”

4. Pure Barre

Jena also likes to “mix it up” when it comes to exercise. She loves Pure Barre classes, a fusion of yoga, Pilates, and ballet and a “full body, low impact workout” for everybody, according to the brand.

Here is her latest workout, “such a good series to work the pull muscles and the ABS,” she says.

Jena Sims Koepka is a lot of things. She’s a former pageant contestant. She has her own charity, Pageant Of Hope. She’s a fashion designer.

Read on to see 5 ways Jena Sims Koepka stays in shape and the photos that prove they work.

Koepka shared some of her favorite workouts in an interview with FOX News. She says that she likes to weight train to help her stay in shape. “I want loud music, heavy weights,” Koepka explained. “For my body type, I like to lift weights because I don’t need to do a lot of cardio. I find that lifting weights has been the most beneficial."

2. She Takes Fitness Classes

Koepka tells FOX News that she also likes to take fitness classes to help her stay in shape. "My favorite type of workout is F45. It’s just a 45-minute class. And I think I like it so much because they play amazing music and it’s so loud. I’m not a calm, soothing Pilates, yoga princess. I’m like, ‘Scream at me.’ I want to be dripping sweat.”

3. She Works Hard

Koepka tells FOX News that she works hard, despite what others might think. "I think the biggest misconception is that I don’t work," she said. "And that couldn’t be further from the truth. It’s funny, I have some people telling me, ‘You need to just subdue yourself…’ And then I have other people going, ‘She doesn’t work, she just wants to spend his money.’ And I’m like, ‘Y’all have no idea.’ I’ve been working hard. I’ve supported myself as an actress in LA for all of my 20s. I’ve probably shot over 200 TV commercials since moving to Florida. I work as an influencer on Instagram. I know people might not consider that to be a job, ‘cause I don’t sit behind a desk all day. But it's a job. I make great money."

4. She Skis

Koepka spends a lot of time outside. One thing she does to stay in shape is going skiing. Koepka shared these photos on Instagram of herself, her husband, and his brother skiing in Big Sky. The Canadian Ski Association states, “It’s well documented that skiing and snowboarding benefits cardiovascular health, overall fitness, strength, coordination, balance and more. Regardless of your health and fitness goals, strapping on a pair of skis or a snowboard is sure to fulfill some of them. Due to the versatility of skiing and snowboarding, it can encompass the benefits of a cardio workout, high-intensity interval training (HIIT) session, and strength training session, all in one fun activity.”

5. She Wants To Help Others

Through her organization, Pageant Of Hope, Koepka seeks to empower other women who compete in pageants. "When you lose a pageant, you feel like a failure,” she tells FOX News. “And then when you win a pageant, you’re on top of the world. So I created a pageant where there aren’t any losers. Everyone leaves a winner… I’ve been touched by how excited these kids get when they’re crowned. And when we do our mini makeovers, we teach self-confidence, inner beauty. But we also make them feel beautiful on the outside as well. Everyone deserves to feel beautiful. And you can see them come out of their shells. Their postures change. They’re striking poses at the end of the day."
