📋 Drama Overview
Everything you need to know before you hit play.
Lee Mi-ran walks into Do Hyeon-joong’s gym convinced it’s a nightclub, which tells you everything about the state of her judgment three drinks into a bad breakup. He’s a former world-champion bodybuilder who vanished from competition years ago and now spends his nights keeping a struggling 24-hour gym alive on stubbornness alone. His pitch to her is blunt to the point of rude — total life care, no shortcuts — and it should be a dealbreaker. Instead it’s the thing she can’t stop thinking about.
What follows resists the easy version of this premise. Pump Up the Healthy Love isn’t really interested in Mi-ran’s body changing so much as her relationship to herself changing, and it uses Hyeon-joong’s own unfinished business — a mentor he’s avoided, a gym he refuses to let die — to make the point that neither of them is actually fixed yet. Jung Eun-ji plays the frustration and the small victories with equal conviction; Lee Jun-young lets Hyeon-joong’s gruffness slip just enough to keep him sympathetic rather than insufferable. KBS2’s Wednesday-Thursday slot rarely gets this much sincerity out of a gym-set rom-com.

Spoiler Warning — This section covers the full finale of Pump Up the Healthy Love. Stop here if you haven’t finished the series.
What actually happens Do Hyeon-joong and Lee Mi-ran’s relationship becomes public right as the 24-Hour Health Club’s closure looks certain, and Mi-ran’s ex, Yeom Jun-seok, resurfaces to admit the breakup that started her journey was about his own insecurity, not her body. Mi-ran takes the year-long Hawaii program anyway — the finale’s clearest statement that loving Hyeon-joong was never going to replace choosing herself. She returns a year later to a gym relocated to a thriving rooftop space, with Rosa and Alex established in their own right and Hyeon-joong having rebuilt his sense of purpose without her standing in for it.
What Mi-ran’s arc actually proves The finale’s real subject is whether Mi-ran ever stopped needing outside validation, and the answer arrives in the choice itself — she leaves the man she loves for a year without asking him to wait, and he doesn’t ask her to stay. That’s the whole thesis the show spent twelve episodes building toward. Her body was never the problem her ex made it out to be. Neither was her relationship. The problem was always whose approval she was training for.
Why Kang Sol’s death matters to the ending Kang Sol’s illness and death in episode 10 aren’t a detour from the romance — they’re the event that forces Hyeon-joong to confront the same avoidance pattern that’s defined his relationship to his mentor and his gym. Losing her a second time, after losing his competitive career, is what finally makes him let the community carry him instead of the other way around. Without that loss, his reunion with Mi-ran in the finale would read as convenient rather than earned.
What the gym’s survival means The rooftop relocation isn’t just a happy-ending flourish — it answers the show’s running question of what the 24-Hour Health Club actually is once you strip away the building. It was never really about the address. It was about Hyeon-joong’s refusal to let his mentor’s legacy, and the people who showed up for him, disappear along with his own championship years. The new space proves the thing survived the thing that almost killed it.
The KDW verdict on the ending Pump Up the Healthy Love earns its reunion by making both leads leave before it lets them stay. Mi-ran gets Hawaii; Hyeon-joong gets a year of standing on his own. The show could have rushed the finale toward a proposal or a montage of matching gym gear, and it doesn’t — it trusts that a year-later reunion, quiet and unhurried, says more about what they built than a bigger gesture would. For a drama that started as a gym-versus-nightclub mix-up, that’s a genuinely earned landing.

Our honest read on why this drama is worth your time — and who it’s for.
🏋️ Gym as Sanctuary
😢 Grief Between Reps
❤️ Earned, Not Rushed
There’s a moment early on where Hyeon-joong tells Mi-ran, without softening it at all, exactly what’s wrong with how she’s been living — and the show trusts that bluntness to be the hook rather than a red flag. It’s a risky choice for a rom-com lead, playing someone whose love language is closer to a drill sergeant’s. Lee Jun-young makes it work by never letting Hyeon-joong’s harshness curdle into cruelty; there’s always visible care underneath the volume. It’s the same trick that made My Lovely Boxer work — a sports-adjacent romance where physical toughness turns out to be the least interesting thing about the tough character.
Jung Eun-ji’s Mi-ran carries the show’s emotional register almost entirely on her own for the first four episodes, and she’s good at the unglamorous version of heartbreak — the kind that curdles into spite before it resolves into anything useful. What’s smart about the writing is that it doesn’t rush her past that spite phase to make her more likeable. She’s allowed to want to get fit purely to make an ex regret something, for longer than most rom-coms would risk. Like the rooftop-apartment healing at the center of Doctor Slump, the show understands that recovery looks messier and pettier than the montage version, and it’s better for showing that mess.
Kang Sol’s arc is the drama’s biggest gamble, and it mostly pays off. Introducing a potential love-triangle rival in episode 8 only to reveal, within two episodes, that she’s terminally ill and searching for genuine connection rather than romantic competition, could have felt manipulative. It doesn’t, mostly because the show never plays her illness for a cheap twist — it uses it to reroute the entire back half toward grief and community instead of jealousy. The gym members rallying around Hyeon-joong afterward is the show’s best sustained stretch.
