Jena Sims Koepka in Two-Piece Workout Gear Shares "Core Workout"

Jena Sims Koepka is working on her core – in her exercise clothes. In a new social media post the golf wife shows off her strength and amazing body during an exercise circuit. "Cove + Core + Pulling," she captioned the Instagram video, demonstrating every move in the video. How does she approach diet, fitness, and self-care and what is her core workout? Here is everything you need to know about her lifestyle habits. 

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."

"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."

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."

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. 

1. roll up w/ leg extended
2. tailbone raises w/ ball between ankles and arms overhead
3. plank rows
4. assisted band pull ups
