Heavy Bass, Light Head: The After-Dark Gym Classes Rewriting the Alt Night Out

It is 8pm on a Thursday in a railway arch in Hackney, and the room is lit like the inside of a vampire’s fridge. Red bulbs, a single strobe, a mirror ball doing slow rotations in the corner. The bass is not a playlist. It is a presence. Around twenty people in black shorts, mesh tops and silver chains are moving in time to a remix of something that sounds like Nine Inch Nails falling down a stairwell. This is not a club. It is a darkwave workout class, and it is absolutely the best night out I have had in weeks.

The room where the warm-up is a mood

The format is simple, and that is the point. A trainer leads a circuit or a dance-cardio set while a DJ or a laptop feeds the room a diet of industrial, EBM, synthpop and the harder end of darkwave. The lights stay low. The mirrors are either covered or ignored. There is no fluorescent glare, no Top 40 grin, no instructor shouting about summer bodies. Instead, there is a shared understanding: we are here to sweat, but we are also here to feel like we are somewhere.

Sessions run from 45 minutes to an hour, and they tend to land between 7pm and 9pm. That timing matters. It is late enough to feel like an event, early enough to be home by 10.30 with a shower and a snack. For people who love the texture of a club but not the 2am taxi queue, the 4am kebab or the three-day recovery, this is the sweet spot. You get the bass, the black, the collective movement and the permission to be a bit dramatic. You just also get your steps in.

Who puts the cult in circuit

The people behind these nights are rarely traditional gym chains. More often they are personal trainers with a foot in the alternative scene, promoters who wanted a daytime-adjacent project, or small studios that already cater to queer, neurodivergent and alt crowds. In Manchester, an Ancoats studio runs a monthly industrial strength session with a live DJ. In Glasgow, a Leith-based trainer has been packing out a darkwave spin class with a dress code that reads ‘black, breathable, a bit much’. Bristol has a Stokes Croft circuit night that ends with alcohol-free cocktails and a playlist you can actually name. London, predictably, has several, from Peckham to Dalston, and they sell out faster than you can say ‘fishnet gym leggings’.

Prices tend to sit between £10 and £18, which is cheaper than a club ticket plus drinks, and roughly the same as a boutique fitness class. The equipment is basic: mats, light dumbbells, resistance bands, maybe a punch bag. Nobody is asking you to deadlift a coffin. The point is movement, not punishment.

The dress code is the point

Here is where the style angle gets interesting. Gymwear has spent the last decade being beige, sculpting and deeply boring. Darkwave workouts have given it a goth edit. People are wearing black breathable mesh, layered over sports bras and vests. Cargo trousers with elasticated cuffs. Graphic tees for bands that broke up before the trainer was born. Silver rings, small hoops, the occasional choker that is definitely not gym-safe but looks excellent in the red light. Trainers stay practical — you are not doing burpees in platforms — but the rest is a mood board.

The result is a room that looks like a club and smells like a gym, in the best possible way. It is also a quiet act of reclamation. For anyone who has felt out of place in a mainstream fitness space — too queer, too fat, too alternative, too much — the dress code is a signal. It says: you can bring your whole self here, and your whole self can wear black.

No 2am finish, no 6am regret

The appeal is not just aesthetic. A lot of people in these rooms are sober, sober-curious, or simply tired of the financial and emotional cost of a big night out. They want the social contact, the music and the endorphins without the hangover. Darkwave workouts offer that in a contained package. You arrive, you sweat, you chat, you leave. There is a WhatsApp group. There are post-class coffees and the occasional alcohol-free pint. There is no pressure to stay out until the bouncers turn the lights on.

For the neurodivergent crowd, the format can be a relief too. The lighting is low, the instructions are clear, the music is predictable in its unpredictability, and nobody is trying to make you do a trust fall. You can be in a room full of people without having to make small talk for four hours. That is a nightlife service, whether the venue calls itself a gym or not.

Etiquette: sweat, don’t spectate

The unwritten rules are worth knowing. Don’t treat it as a pickup joint. Don’t film people without asking. Do respect the dress code if there is one, but don’t police how others interpret it. Do bring water and a towel, because the red light is forgiving but your fellow attendees are not. And do remember that the person next to you might be here because it is the only hour of their week that feels like theirs. The vibe is vampy, not vicious.

The catch

None of this is radical if it stays a novelty for people who can afford £15 on a Thursday. The scene will only matter if it keeps its doors open to beginners, to older bodies, to people who cannot afford boutique fitness. The best versions of these nights are the ones that feel like a community project with a good soundsystem, not a marketing stunt with a smoke machine.

Still, there is something genuinely lovely about a room full of black-clad strangers doing squats to a remix of ‘Blue Monday’ and then going home at a reasonable hour. It is nightlife without the debt. It is fitness without the fluorescent shame. It is, dare I say, a little bit Vamper. Fangs on, trainers on, last train home.
