KBS 2TV’s New Drama Blends Fitness and Romance in ‘24-Hour Health Club’ Premiere

The much-anticipated KBS 2TV Wednesday-Thursday series ‘24-Hour Health Club’ finally premieres tonight at 9:50 PM KST, offering viewers a fresh blend of fitness, romance, and comedy.

Set in a 24-hour gym, the series follows Mi-ran (played by Jung Eun-ji), a woman reeling from a heartbreaking breakup with her boyfriend Yeom Joon-seok (played by Jung Wook-jin) who seeks solace in what she thought was a dance club—but discovers instead the intense world of weight training.

Still mourning her lost love, Mi-ran’s chaotic dance session leads her to unexpectedly register as a gym member, guided by the eccentric and energetic gym head Do Hyeon-jung (played by Lee Jun-young). Described as a ‘fitness freak,’ Hyeon-jung is on a mission to transform people’s bodies—and lives. “Yes, this is a club—the hellish club of body fat! We’re open 24/7!” he exclaims in the teaser, pulling Mi-ran into the world of reps and gains.

As Mi-ran begins her sweat-filled journey with Hyeon-jung, she realizes that her true transformation lies beyond physical change. What starts as heartache-driven desperation soon turns into a process of rediscovery. Viewers can expect comic moments, emotional breakthroughs, and unexpected romance as sparks begin to fly between Mi-ran and Hyeon-jung.

The drama’s teaser has already captivated fans, showing the duo inching closer—from lingering eye contact to a near kiss, creating palpable on-screen chemistry. Hyeon-jung’s rule of “no personal feelings in the gym” starts to crack as his heart betrays his words, leading to hilarious and heartwarming situations.

Curiosity peaks when Hyeon-jung utters the unforgettable line, “There’s a callus inside this heart,” hinting at his vulnerable side behind the muscle-bound bravado. With a backstory that saw him rise from a frail child to a legendary bodybuilder, only to now run a run-down gym—his journey offers both inspiration and intrigue.

With its comic tone, emotional core, and fresh twist on the rom-com genre, ‘24-Hour Health Club’ is poised to strike a chord with viewers seeking relatable transformation arcs and laughter-filled motivation.

Tune in tonight on KBS 2TV at 9:50 PM to catch the premiere episode you didn’t know you needed.
