Alexandra Daddario turned heads in May 2024 as she pumped iron in a tiny bikini on Instagram. The Baywatch star, 39, was actually pregnant with her first child as she shared footage of herself working out, but her October-born son wasn't big enough to form a bump yet. Thrilling fans with her jaw-dropping body, Alexandra showed "two hard-working girls on vacation" as she opened her gallery with beach action, but it wasn't long before she was upping the ante in the gym. Alexandra and husband Andrew Form made headlines last fall for debuting their baby boy, whose name has not yet been revealed.

Making instant headlines with her bikini and gym vibes, Alexandra closed her gallery lying on a workout bench while barefoot. Lifting two heavy-duty dumbbells while flashing her abs, the A-lister showed off her dangerous curves in a black string bikini, also checking boxes for showcasing her abs. Here, Daddario added a baseball cap as she kept her reps slow and steady.
Alexandra Daddario and her muscles were already making headlines in 2017 when she was cast in the movie Baywatch. When The Daily Mail published the actress confirming she'd gained weight for her role, users quickly commented. One noted her iconic beauty and curves, saying that she should have "been Wonder Woman." The superhero role was made iconic that same year by actress Gal Gadot.

Speaking to Women's Health about her transformation, Alexandra Daddario revealed:
"It was kind of amazing, the transformation I went through." The mom of one continued: "For Baywatch, I started doing weight training, which I had never done before, and I saw a huge difference." Alexandra has since made pandemic headlines for her home yoga sessions. She then fronted both Alo Yoga and Aerie.
