1. Follow the 80-20 Rule

Olivia is all about healthy eating, most of the time. "I stick to the 80-20 rule," she explained to Hamptons magazine. "Eighty percent of the time I'm really good, and then 20% of the time I allow myself to eat, not whatever, but indulge a little more, I guess you could say." What does she eat? Lots of healthy fiber and protein throughout the day, starting her morning off with coffee with oat milk and a bowl of fruit, avocado toast and egg whites, followed by a salad for lunch. "I love chicken and any veggies with a miso vinaigrette," she told Women’s Health.

2. Don’t Stop Moving

Olivia makes sure to constantly move, which is why she created the 20-minute Cardio Challenge on social media. "That is basically 20 minutes of cardio at whatever speed you want. I've been doing it with my followers encouraging them to join the challenge and just do whatever feels right for 20 minutes," she explains. She adds that the great thing is that "it doesn't feel too overwhelming," and it is an easy way to get moving. "Before you know it, it's over."

3. Find Portable Workout Methods

Olivia makes sure to get a workout in anytime, anyplace. One of the ways she does this is with the P.volve workout method, a low-impact method with portable equipment that can be done anytime, anyplace. "The P.volve workout is great for me because I travel a lot," she told Shape. "There are 3-pound ankle weights, 2-pound free weights, and tons of elastic bands that you can use in different ways."

4. Snack Healthy

Olivia always keeps healthy snacks around to avoid indulging in junk. "I'm obsessed with nuts," she revealed to Women's Health. She also mixes sweet with salty. "I need energy on set, so I like the raisins and the chocolate," she explained.

5. Be Consistent

It’s all about consistency, per Olivia. "I've noticed it's very important to be consistent with workouts," she told Shape. "I think it's really easy for people to go through phases where they're really intense with their workouts and then they kind of fall out of it." So, she makes sure to exercise daily. "I try to stay active as much as I can by doing low-impact, high-intensity workouts so that I'm consistent and I don't wake up one day and realize it's been two weeks and I haven't worked out."

Read on to see 5 ways Olivia O’Brien stays in shape and the photos that prove they work—and to get beach-ready yourself, don't miss these essential 30 Best-Ever Celebrity Bathing Suit Photos!

1. She Channels Her Negativity Into Music

O’Brien, like many other songwriters, likes to draw from her personal experiences to write songs. She tells Cosmopolitan that she would channel her negative experiences into lyrics. “I used to write pretty much only about when I was sad and when I was going through something that was really hard for me,” she said.

2. She Has A Lot Of Support

In an interview with OnesToWatch.com, O’Brien talked about how she achieved fame. She says that she’s lucky to be on a good label and have a lot of supportive people around her. “I think if I didn't have my label and those people helping me, I would literally still be living in Napa and wouldn't be doing music. Because ‘i hate u, i love u’ was the only song that I released.”

3. She Pushed Herself

O’Brien tells OnesToWatch.com that she really pushed herself when it comes to her career. She says that this helped with her success. “If I hadn't got on it, and told myself, ‘I want to do this now,’ I wouldn't be anywhere, and that song would've just came and passed. I would've just been left behind. So I'm happy that I had the initiative and went for it.”

4. She Moved Past The Bullying

O’Brien is open about the amount of bullying she faced when she was young. However, she tells OnesToWatch.com that she has moved past it, as she knows more important things are ahead. “Even though it's really impossible, you have to realize that high school and elementary school, middle school, whatever… in the end, you're going to be past that and have a completely separate life from that. Yeah, growing up is important and the memories you make are important, but the people that are mean probably aren't really going to go anywhere in life - because they're mean and there's obviously something going on with themselves. So you just have to remember that. Remember that one day you'll be 35 and think, 'Wow, I can't believe I ever let those dumb people affect my life.'"

5. She Swims

O’Brien loves to spend time in the water. She has posted several photos and videos on Instagram of herself enjoying time at the beach and going for a swim. She posted this video on Instagram of herself enjoying a pool day while on her Mexico vacation. O’Brien captioned the video, “What happens in slayulita, slays in slayulita.”

I just feel like it’s an easy meditative way to work out. I can really zone out during that workout." "The feeling of being part of something bigger and the camaraderie forged in group fitness classes is something that quite simply can’t be replicated. Group fitness classes exude positivity, and serve as a welcome invitation for people of all different ages, backgrounds, and ability levels to come together in one inclusive experience to move with passion and intention, all without judgement or expectation," says ACE Fitness.

Culpo also loves Pilates as a way of working out. She tells HollywoodLife, “I think Pilates is also another almost meditative type of workout. You can just forget everything and go through the motions and breathe.”

For cardio, Culpo is an avid runner. She says to HollywoodLife that she aims to get a run in as often as she can, even with cold weather. “I like to run. It’s a little harder in the winter because it’s chilly.”

When Culpo needs to eat healthy, she aims to eat a low-carb diet. “I try really hard,” she told HollywoodLife. “I really try to cut out carbs when I’m not working. When I’m preparing for something and being good, I cut out carbs. So my ideal good day would be egg whites, avocado, turkey bacon for breakfast. Then, for lunch, I would have a salad with protein, and for dinner, I would have veggies with protein.”

5. She Cooks

Culpo loves to make her own food. She says to Stylecaster that she likes to cook healthy meals for herself. “I have made everything from sweet potato toast to ginger-soy sautéed vegetables. I feel the healthiest when I make the food myself.” "In addition to being an excellent source of vitamins A and C, sweet potatoes are a good source of fiber, vitamin B-6 and potassium. And like all vegetables, they're relatively low in calories — one-half of a large sweet potato has just 81 calories," says the Mayo Clinic.
