K-Drama ’24-Hour Fitness Club’ Promises Rom-Com Sparks Inside a Gym

Korean drama fans, get ready to feel the burn—emotionally and physically. KBS2’s highly anticipated new Wednesday-Thursday series, 24-Hour Fitness Club, is set to premiere on May 30 at 9:50 PM KST, bringing a unique blend of gym culture, personal growth, and romantic comedy to late-night TV.

The drama stars Lee Jun-young as Do Hyun-jung, an overzealous gym trainer also known as a “fitness freak,” and Jung Eun-ji as Lee Mi-ran, a gym newbie (nicknamed “Hell-inie”) who ends up becoming his student—and possibly more. Recently released couple posters have already set fans’ hearts racing with strong chemistry and playful tension that hint at what’s to come.

Striking a pose with a barbell and a warm sunset backdrop, the poster captures an intimate backhug that feels more dreamy than sweaty. Their smiles, shared gaze, and physical proximity tease a slow-burn romance sure to charm viewers. The tagline “Wanna build muscles with me?” only adds to the drama’s comedic romantic flair.

24-Hour Fitness Club isn’t just about gains and gym routines. It’s a light-hearted but emotional romp into the lives of people trying to rebuild themselves—inside and out. Hyun-jung is determined to change Mi-ran’s life, and along the way, he seems to be changing his own heart. From transformative training montages to accidental emotional breakthroughs, this series aims to deliver laughs, sweat, and maybe even a few tears.

This gym-based rom-com is being brought to life by director Park Joon-soo, known for Gaus Electronics and God of Music, and writer Kim Ji-soo, who penned Birthcare Center. Together, they promise a genre mash-up that’s both fresh and full of heart.

If you’ve ever fallen in love between reps or dreamed of gym crushes turning real, 24-Hour Fitness Club might just be your next binge-worthy obsession. Mark your calendars—the afterhours are about to get a lot more interesting.
