Hailey Bieber proved she's the queen of effortless summer style. The Rhode founder took to Instagram to share a stunning mirror selfie that immediately captured fans' attention, posing in a vibrant yellow string bikini that perfectly showcased her toned physique.
Standing in front of a marble vanity, Hailey kept the focus firmly on her minimalist look as she snapped the photo on her phone.
The bright sunshine-yellow two-piece featured classic triangle cups and tie-side bikini bottoms, creating a timeless beachwear look that complemented her bronzed glow.
The model wore her brunette hair slicked back into a neat bun, allowing her natural beauty to take center stage. She opted for fresh, understated makeup with softly defined brows and a nude lip, while delicate earrings and her wedding ring added subtle sparkle.
Hailey also showed off her collection of fine-line finger and hand tattoos, keeping her accessories pared back in keeping with her signature quiet luxury aesthetic.
Hailey's enviable figure is no accident. The mother of one recently revealed that she has moved away from Pilates in favour of heavier strength training.
"I think [Pilates] is a little over," she admitted in an interview with Time. "I love Pilates, I really do. But I think it's become a little bit of a fad, and it's really hard to find really good teachers that care about good form."
Instead, Hailey now focuses on heavy resistance training and progressive overload under the guidance of celebrity trainer Kirsty Godso.
Kirsty explained that every programme is tailored around her clients' individual lives and goals.
"These are some of the most scrutinized women in the world – there's immense pressure on them to look a certain way. So the most important thing for me is making sure they feel good for themselves, not just for everyone else's expectations," she told Remix magazine.
She added that while every client follows foundational strength work, each programme evolves depending on career demands and different stages of life.
"In terms of how I approach their training, there's foundational work that stays consistent across the board, but then there are very specific demands depending on what's happening in their careers, like Hailey navigating pregnancy and postpartum."
Kirsty continued: "My main objective is always keeping them ready at a baseline level of strength and conditioning – because in their world, there's always something happening. A major shoot can pop up with 48 hours' notice. They're some of the hardest-working people I've ever met."
Hailey also credits her toned physique to a balanced approach to nutrition rather than restrictive dieting.
Speaking previously to ELLE, she explained: "On a regular day, breakfast is usually eggs or oatmeal, some type of healthy protein, or a smoothie. Lunch is usually salad, fish, grilled veggies, or maybe a sandwich."
She continued: "I don't really eat a lot of gluten, so I'm trying to be particular. I love a good kale Caesar salad, but with no croutons. That's usually one thing I leave out. Dinner is usually kind of along the same lines; some sort of vegetable or pasta."
