Haley Cavinder is having the kind of spring that would make anyone want to hit the gym — and the beach. The former Miami Hurricanes basketball star turned SI Swimsuit cover model just dropped a March bikini shoot alongside twin sister Hanna, and the internet is completely losing it. Between her February SI Swimsuit debut, a Bahamas bachelorette bash, and a June wedding to Dallas Cowboys tight end Jake Ferguson incoming, Haley's bikini era has officially arrived — and it's giving everything.

The March Photoshoot That Has Everyone Talking

Earlier this month, Hanna and Haley Cavinder teased a new bikini photoshoot on their Instagram, and the preview clip alone hit hundreds of thousands of views. The twins wore two-piece suits paired with open long-sleeve cover-ups and cowboy hats — a nod to Haley's cowboy-loving fiancé, Cowboys tight end Jake Ferguson. Their energy? Completely unbothered. Their bodies? Absolutely serving.

Fan comments poured in immediately. One follower summed up the collective reaction: "HOLY GUACAMOLE YOU GUYS ROCK." Which, honestly, tracks. The Cavinder Twins have been building their fitness and brand empire for years, but this spring, Haley in particular is radiating a new level of confidence — and it's easy to see why.

Haley's SI Swimsuit 2026 Debut — A Cover Girl Moment

Before the March photoshoot, Haley made her Sports Illustrated Swimsuit 2026 digital cover debut — shot at the dreamy Captiva Island in Fort Myers by photographer Katherine Goguen. This is a massive moment for a former college athlete who built her platform through basketball, NIL deals, and relentless social media hustle. SI Swimsuit Editor-in-Chief MJ Day tapped her, and now the world is watching.

Haley's own words on the SI feature feel like a mission statement: "I think Sports Illustrated Swimsuit is such a great community full of empowering women — and to be around such hardworking women is really inspiring." That's not just a quote for a press release — that's the vibe she's actually living.

Pre-Wedding Fitness and the Twogether App

Here's the part that's got the fitness crowd buzzing: Haley and Hanna recently shared before-and-after progression photos on their Twogether app, showcasing what months of focused glute workouts look like in a two-piece. The twins captioned one transformation post with "We used to chase skinny" — a body-positive message that genuinely resonates with their audience. Haley has been training specifically for her June wedding, and the results speak for themselves.

She even teased a bridal boot camp workout plan dropping soon, with Under Armour backing. For the fitness-obsessed girlies who want that same toned-and-glowing energy for their own beach trips, the Cavinder Twins content is basically a masterclass right now.

The Bachelorette in the Bahamas

And yes, the bachelorette party already happened — and it looked absolutely unreal. Haley and Jake merged their bachelor and bachelorette parties at Baker's Bay Ocean and Golf Club in the Bahamas (yes, private jet included). Haley showed up in a white shell-adorned string bikini accessorized with a straw cowboy hat and a belly chain spelling out "BRIDE." Naturally, she looked stunning. Her bridal swimwear lineup also included a white bandeau bikini with pearl accents and a white balconette swim top with white linen chaps.
