Amid the sun-drenched beaches of Thailand’s Ko Samui, Sophia Thomalla, the charismatic girlfriend of world number two tennis star Alexander Zverev, has been turning heads with her unwavering commitment to fitness. The 35-year-old German actress, model, and television presenter recently shared a glamorous gym mirror selfie on Instagram, showcasing her toned physique and dedication to staying active even while on vacation. The post, radiating confidence and discipline, comes as Zverev prepares for a crucial clay-court campaign at the 2025 Madrid Open, where he aims to build on his recent BMW Open triumph in Munich.
Thomalla’s fitness journey has been a consistent theme throughout Zverev’s 2025 season, with her gym selfies becoming a staple on social media. From Argentina to Acapulco, Miami to Monte Carlo, she has documented her workouts with stylish flair, often captioning posts with witty remarks that reflect her surprise at her own discipline. “I can’t believe I actually made it to the gym,” she wrote during Zverev’s Argentina Open campaign, a sentiment echoed in her latest Thailand post, where she flexed her muscles in a sleek black sports outfit. Her dedication is not just personal; it’s a source of inspiration for Zverev, who credits her presence with giving him “peace and security” on the ATP Tour. “I think for tennis players it is always very important who you have next to you,” Zverev said in 2021, a testament to Thomalla’s role as his steadfast supporter.
The couple, together since 2021, has navigated the highs and lows of Zverev’s career with a bond that thrives despite their demanding schedules. Thomalla, born into a family of actors in East Berlin, has carved her own path in the entertainment industry, starring in German TV shows like Der Bergdoktor and hosting the local adaptation of Are You the One?. Her vibrant personality and outspoken advocacy for women’s rights have earned her a loyal following of over 1.3 million on Instagram, where she blends fitness updates with glimpses of her life with Zverev. Their relationship, marked by a seven-year age gap, has faced scrutiny, but Thomalla remains unfazed. “I don’t think anything of it,” she told reporters, dismissing critics. “It doesn’t really matter to me, and it was clear from the start that people are suspicious.”
While Thomalla soaked up Thailand’s tropical allure, posting a stunning beach selfie in a red dress, Zverev was back on the grind in Madrid, fresh off his 24th ATP title in Munich. His 6-2, 6-4 victory over Ben Shelton at the BMW Open marked a turning point in a season that began with promise but faltered after a runner-up finish to Jannik Sinner at the Australian Open. Early exits in Monte Carlo, Argentina, and Indian Wells—where he became the first top seed to lose his opening singles match after winning the first set—tested his resolve. Yet, Thomalla’s absence from Madrid’s early rounds hasn’t dimmed her support; she’s expected to join Zverev soon, as she did in Munich, where her cheers from the stands fueled his success.
Thomalla’s Thailand getaway reflects the couple’s ability to balance work and play. Their romance, sparked through a mutual friend in 2020, has weathered challenges, from Zverev’s past controversies to the relentless pace of their careers. “We don’t have a simple life together,” Thomalla admitted in a documentary, highlighting the contrast between Zverev’s rigorous tennis schedule and her unpredictable acting commitments. Yet, moments like their cozy selfie at a Boca Juniors game in Argentina or their fist-bump ritual during Zverev’s Australian Open run reveal a partnership rooted in mutual respect. “This is the coolest version of German you can be,” Zverev joked about their handshake, a lighthearted nod to their shared heritage.
As Zverev eyes a deep run in Madrid, where he’s a two-time champion, Thomalla’s fitness focus underscores the discipline that binds them. Her gym selfies, whether from Thailand’s shores or Miami’s courtside, are more than vanity; they’re a symbol of resilience, mirroring Zverev’s own fight to reclaim the world number one spot. With Thomalla’s return to the stands imminent, the tennis world awaits the next chapter of this power couple’s journey, where love, ambition, and a good workout keep them in sync.
