Marta Kostyuk is heating up both on and off the court. The 23-year-old Ukrainian tennis star, who recently cracked the top 12 in the WTA rankings, just dropped a workout video that has her followers doing double takes. In the clip, she's pushing through a training session wearing nothing but a black swimsuit, showcasing the kind of strength and tone that's helped her climb the ranks.
Kostyuk, who calls Monte Carlo home, posted the video to her Instagram with the caption, “Reset complete 🌊.” The fifth slide in the carousel really steals the show, as she goes through a series of exercises that highlight her athletic build. It's clear this isn't just about looking good—it's about the hard work that goes into competing at the highest level.
Fans couldn't get enough. Comments flooded in, with one admirer joking, “I’d marry myself… Too bad she’s already married!!! 😂😂😂” Another simply wrote, “Stunning workout, that’s clear,” while others piled on with heart eyes and fire emojis. The video has quickly become a fan favorite, blending fitness with a touch of glamour.
This isn't the first time Kostyuk has turned heads with her off-court style. Last summer at Wimbledon, she rocked a wedding-dress-inspired outfit that had everyone talking. Vogue even highlighted the look, and Wimbledon's own social media called it “a tennis-inspired wedding dress and a wedding-inspired tennis dress.” The dress, designed by Wilson, was actually inspired by her own wedding gown—a full-circle moment that fans adored.
With Wimbledon just around the corner (first round kicks off June 29), all eyes are on what Kostyuk will wear next. She's coming off a strong semifinal appearance at the French Open, and her training regimen suggests she's ready to make a deep run at the All England Club. If her off-court content is any indication, she'll bring the same heat to the grass courts.
Kostyuk joins a long line of tennis stars who've used swimsuit content to connect with fans, much like Genie Bouchard's orange swimsuit photo that drove fans wild. But Kostyuk's workout twist adds a layer of athletic credibility that resonates with sports fans who appreciate the grind behind the glamour.
Her recent rise in the rankings—hitting a career-high No. 12—has been fueled by a relentless work ethic. That same dedication is on full display in the swimsuit video, where she's not just posing but actually training. It's a reminder that behind every highlight reel, there's hours of sweat and discipline.
As the tennis world gears up for Wimbledon, Kostyuk is already serving up content that keeps fans engaged. Whether she's breaking down opponents on the court or breaking the internet with a workout video, she knows how to command attention. And with her game at an all-time high, this could be her breakout Grand Slam.
