Gen Z has discovered park aerobics

Going to Lumphini Park at 6pm on a weekday would have seemed deeply uncool three years ago to the demographic now filling it. The aerobics, specifically. The coordinated arm movements, the instructor on a raised platform, the music sitting somewhere between mall PA system and provincial wedding reception. This was, in the taxonomy of Bangkok activities, firmly the territory of a different generation and a different relationship with dignity.

The crowd showing up now is largely in its mid-twenties to mid-thirties, with a significant contingent that appears to have come straight from an office and changed into matching sets in the car park. Everyone knows the steps, and nobody seems embarrassed. The sessions are free, open to anyone, and happening in a public green space in a city that charges for almost everything else, and they have been filling up at a rate that has attracted enough social media attention to make Lumphini’s evening aerobics one of the more discussed lifestyle developments in Bangkok this year.

The moment that crystallised the trend for many people came in early April, when Dada, Miss Grand Kalasin and a Miss Grand Thailand 2026 contestant known for her breakdance-inspired choreography, took to the stage at Lumphini’s Smiley Plaza and led the crowd through a session that drew so many people latecomers spilled onto the surrounding areas. The stage itself was a million-baht donation from LINE MAN Wongnai to the BMA, fitted with international-standard lighting and sound equipment, which is an unusual amount of infrastructure to point at a free public aerobics class and also a reasonable indicator of how seriously Bangkok has started taking this. Dada had gone viral weeks earlier for breaking into hip hop moves during the Miss Grand Thailand swimsuit segment while everyone else walked gracefully, and the Lumphini appearance folded her existing fame into something that felt less like a celebrity appearance and more like a natural extension of where the culture already was.

Something has shifted in how Bangkok’s younger generation relates to the activities it once considered embarrassing by association. The park aerobics boom is the most visible example, but it sits within a broader pattern: the wet market making a quiet comeback among people who used to find it inconvenient, the temple fair as a genuinely desired Friday night, Thai folk music playing unironically in cafes that would have been spinning something Nordic two years ago. The generation that grew up dismissing these things as provincial or dated has started returning to them.

Part of what is driving this is social media. The aerobics class at Lumphini is extremely good content. Colourful, communal, slightly absurd, and free, which is a combination the algorithm responds to enthusiastically, and the content explanation only goes so far. People are not showing up in their hundreds every evening for a reel. They are showing up because it is fun, because it is social in a way that a gym is not, and because standing in a park moving your body in coordination with a large group of strangers turns out to feel surprisingly good regardless of whether anyone is filming it.

There is also something in the economics of it. Bangkok recently ranked number one city in the world for Gen Z according to Time Out’s most recent survey, with 84 percent of young residents reporting happiness with life here and affordability consistently cited as a significant factor. The aerobics class is free, and the park is free, and the growing preference among young Bangkokians for activities that do not require a booking, a membership, or a 200 baht matcha to justify your presence.

What the aerobics trend suggests is less about the activity itself and more about how this generation is starting to relate to Bangkok. The city’s young people have spent the better part of a decade orienting themselves around the new, the international, and the aesthetically considered, and there is nothing wrong with any of that, but there is something in the turn toward the park, the free class, the activity their parents already knew about, that reads less like nostalgia and more like reclamation.

The aunties were doing this the whole time, and it took a TikTok to make it cool, and then it turned out it was just good.
