Julianne Hough Shows Off Her Fit Figure While Doing "Sauna Stretches"

Julianne Hough turned up the heat with her latest fitness moves.

The Dancing With the Stars host showed off her fit figure in an itty-bitty brown bikini while breaking a sweat in a sauna at Ibiza's Six Senses Spa. But instead of sitting idly for the therapeutic treatment, Julianne decided to bust out a few stretching exercises.

She captioned her June 7 Instagram video, "Six Senses Sizzling Sauna Streaches [sic]" with Tommy Richman's song "Million Dollar Baby" playing.

In the short clip, the 35-year-old did a variety of Pilates and yoga poses, including side bends and a downward dog stretch.

Julianne's energetic sauna session comes as no surprise. After all, she recently discussed why she stays active no matter the occasion.

"Movement in general," she exclusively told E! News in March, "whether it's 10 minutes or five minutes of something, I have to move my body."

As she put it, "For me, movement equals life. Motion equals emotion."

At the time, Julianne revealed she works out at least five times a week—but she's not focused on how she looks, rather, how she feels.

"This is the age of energetic health," the Kinrgy founder explained, "because if you can change your energy, then you can change your mindset, and then you can change your physicality. We've been going about it the other way, which is: If I'm physical, then my body is going to look good. But if you focus more on your energy, then you get fitness as a plus."

For the Everything We Never Knew author, fitness needs to be fun and functional. "The more you move, it directly affects the way you feel," she noted. "Whether it's a Kinrgy class or doing Pilates or yoga...I need a little bit of something different and unique so that my brain stays active."

Of course, Julianne isn't the only celebrity to share the benefits of exercising. Keep reading to see how your favorite stars like to break a sweat.

Eight months after welcoming her daughter Matilda with Tom Pelphrey, Kaley noted why she loves doing treadmill workouts amid her postpartum fitness journey.

"Putting that incline up is so good for your muscles, and for your circulation," she told Today.com in an interview published Nov. 22. "I'll also walk backward, which is amazing for your butt and legs. It pretty much works everything."

After having a transformative year in 2023, Becky revealed how fitness played a major role. "I know at the end of the day who benefits from a healthier me the most—myself," she told E! News. "Eventually, if you dedicate yourself to it, you will have lived your life longer with this habit than you ever did without it. At least, that's the way I like to think about it."

Her go-to workouts? "If it's a home work out, if it's stretch, if it's going outside for a walk—I try to be as consistent as I can be."

The Grammy winner explained how moving to New York City helped kickstart her health and fitness journey. "Walking in the city is quite the workout," Kelly told People in an interview published Jan. 3. "And I'm really into infrared saunas right now. And I just got a cold plunge because everybody wore me down."

 Julianne told E! News the exercise she always blocks out time for when she has a jam-packed schedule.

"I know that I can walk around the hills with my dog," the Dancing With the Stars said. "That's key because I have to get her out, too. But movement in general, whether it's 10 minutes or five minutes of something, I have to move my body."

And when she has more time to break a sweat, she added, "Whether it's a Kinrgy class or doing Pilates or yoga, the fact that we get to combine all of those modalities is my favorite because I love versatility."

"I always move, even for a few minutes each day. Sometimes I'll go into a room, turn up the music and just dance. It's a great way to let loose and feel great."

The record producer opened up about his love for golfing and how it's helped him slim down.

"I do it every day and I get a chance to sit on the golf cart or walking about to answer an email or a call and handle my business," he told Us Weekly in an interview published Sept. 20. "It's so much [more] pleasurable, meaning [being around] the nature, the sun. It cleanses me."

"Honestly, my favorite way to break a sweat right now is playing VR. We got a virtual reality headset right as everything was shutting down and it's been AMAZING during quarantine. There are so many games that make you work up a sweat and it's so awesome. I am genuinely so sore after I play."

"Under normal circumstances it's going to the gym, but right now I'm taking online classes with my Pilates instructor Britni Lariviere. I'm also trying to jump rope—2,000 strokes each day."

"Family bike rides are big for us right now and I always try to carve out thirty minutes for pilates with Andrea Rodgers and foam rolling with Lauren Roxburgh."

"Running and listening to music. The best outlet I've found these last few months being stuck in the house! I feel so great and pumped up after."

"My favorite way to break a sweat is mix of sex, PRx Performance, hiking, biking."

"By connecting with my audience and motivating them through my Brooke Burke Body fitness app! I've been live streaming on the app as well as on my Instagram since the beginning of quarantine in an effort to make fitness fun and innovative. I especially love walking my viewers through total body cardio parties, which is when I crank up the music, let them find their rhythm and let the booty burn. Cardio kicks up your heart rate, so if you're not sweating, you're not working out hard enough!"

"I have been doing a lot of Sculpt, Cardio Boxing and Yoga Classes on the obé Fitness App and virtual classes with Pilates By Amanda. If I don't have a lot of time, I will do Lauren Gores' express workouts on her Instagram."

"During lockdown it's yoga under my own direction. I can go onto so many different tangents and by the time I am done it is often two hours."

"My trainer, Amoila Cesar, gets lots of results out of me by appealing to my 'no quit,' competitive side. He yells and I love it. During quarantine, I got my fix by doing his 6 Weeks of THE WORK on Beachbody on Demand. I also love a rigorous barre class and need daily yoga."

"I've been doing a lot of dancing in my apartment. I'll turn on some music and just go. Sometimes it's more structured, sometimes it's interpretive, sometimes I twerk. Also hiking!"

"My go-to work out is P.Volve, I've gone to their classes for years and now I stream them at home. I try and workout at least 3 to 4 times a week even if its for 30 minutes. Its all about strengthening and elongating your muscles. It's my favorite!"
