“I think we all have our good days and our bad days in how we feel about ourselves. Entering this business, I hated being super skinny. Once I turned 21, I started filling out a little bit, and I was loving my new curves. I appreciated having a booty,” Christina told Health. “I’ve always said that women are way more interesting to look at than men! I have a hard time looking at the early pictures of myself because I remember feeling so insecure. I would never want to relive my 20s—you’re so in your own head and finding your confidence. As you age, you stop comparing yourself to other people and start appreciating your own body and owning it.”

2. She Prioritizes Her Mental Healt

Christina prioritizes her mental health. One of her practices? “I write a lot. Pen to paper has always been grounding and centering for me,” she told Health. “Also, getting outside helps, even if it’s just my backyard. Feeling grass under my feet and looking at trees and clouds helps.”

3. She Does Yoga

Christina also maintains that yoga is good for her body and mind. “Yoga has also been instrumental in helping me,” she told Health. Harvard Health maintains that yoga is a great workout. “Researchers found that people who practiced yoga for at least 30 minutes once a week for at least four years, gained less weight during middle adulthood,” they said. “People who were overweight actually lost weight. Overall, those who practiced yoga had lower body mass indexes (BMIs) compared with those who did not practice yoga. Researchers attributed this to mindfulness. Mindful eating can lead to a more positive relationship with food and eating.”

4. She Takes Baths

Another self-care ritual for Christina? “I love a beautiful hot bubble bath with all of my ingredients and oils! I really make it like a nourishing soup in there,” she told Health. How can baths do your body and mind good? They have been linked to better sleep and even found helpful to minimize anxiety and depression. One recent study even found that they may even boast cardiovascular benefits.

5. She Lifts Heavy Weights

The singer also lifts weights. "Christina does biceps curls with 15-pound dumbbells and chest presses with 20-pounders," Tee Sorge, who trained Aguilera told Glamour. "She knows they're not going to bulk her up. What they will do is help build lean muscle that kicks up your metabolism and make your body burn more calories each day--so you'll lose weight faster."

6. She Does a Lot of Ab Work

According to Aguilera’s trainer, she does 300 to 400 reps of various ab exercises per session. "Your core is your body's center, its foundation. If you're strong there, you're going to be strong and healthy, period,” says Sorge.

7. She Does Interval Training

Christina also does cardio intervals, says Sorge. "Christina slowly jogs for five minutes on flat ground, sprints for three to five minutes, and then does a slow uphill walk for the remainder of the workout. It's amazingly effective at making your body really lean."

1. She Loves to Be Outdoors

“I’m very happy that the world is opening up a little bit. I’m grateful to see my family more now; it always makes me happy and fills my heart with unconditional love. I’m also very excited to see my friends again and spend some quality time with everyone when we can travel safely,” she said of life a few years into the pandemic, to The Thirty. “Of course, it's been great to spend time ‘off the grid’ in a way, too. Over the past year and through the process of building a house in a remote part of the country, I've realized that being outdoors is great for my mental health. Now, I try to go outside more, go on a hike, work out, do my self-care routines as regularly as possible.”

“I like products that include charcoal for its ability to draw out toxins and remove impurities. I look for it in face masks and toothpaste, where it's used for its brightening effect. Also, in case you didn’t know, Dahlia Tequila is filtered through activated charcoal,” she told The Thirty.

3. She Works Out Daily

“Being a Victoria’s Secret model is not just work, it becomes your lifestyle,” the Hungarian model told Us. “So even before I became an Angel, I started to get a routine into my life, working out every day or four times a week and eating in a certain way that works for my body. I’m just doing that.”

4. She Worked Out With an Angel

“I did work out with Alexina [Graham] for awhile because we are really good friends,” she told Us. “It was actually funny that we both got the Angel contract now. We’ve been knowing each other for awhile so I would work out with her.” She added she’d say: “Like, ‘Hey dude, don’t be lazy!’” says Palvin. “Actually, we both wanted [to be Victoria’s Secret models] for so long and when she started to work with VS three years ago, I was like just wait for me, I’m coming, I’ll be there soon. So it’s kinda like, now we’re here, now we have to show the world.”

5. She Says “Listen to Your Body”

"This is me," Barbara captioned one photo. "It took me a while to understand what people meant by 'listen to your body' — it’s not always easy feeling good in our own skin and it takes time, trust me,” she told Sports Illustrated. "I'm still learning," she continued. "Over the past year I've discovered so much about my body, how it can change and evolve. One thing is for sure — only you know what’s best for you."
