From Headphones In to Arms Wide Open

For most of the 2010s, the dominant fitness culture was intensely personal. The rise of the home gym, the on-demand workout app, and the solo-warrior aesthetic — fueled by influencers doing isolation exercises in perfectly lit bedrooms — made fitness something you did alone, for yourself, optimized for your specific biometrics and goals.

Gen Z inherited that world. They came of age with Peloton leaderboards, Nike Run Club solo challenges, and YouTube workout channels that made a personal trainer unnecessary. And then the pandemic hit, isolating everyone further, making the gym not just optional but legally inaccessible for months on end.

What emerged from that isolation wasn’t a deeper love of solo fitness. It was its opposite: a profound, generation-wide hunger for physical togetherness.

The numbers tell a clear story. But the real explanation lives in something harder to quantify: what it feels like to be a young person navigating adulthood in the most digitally connected — and socially fragmented — era in American history.

Working Out the Loneliness Epidemic

In 2023, U.S. Surgeon General Dr. Vivek Murthy issued an advisory that made headlines: loneliness in America had reached epidemic proportions, and young adults were among the most affected. People aged 18 to 34 reported the highest rates of social isolation of any age group — higher even than seniors, who had long been considered the most vulnerable population.

This wasn’t abstract data for Gen Z. It was lived experience. Many entered college during COVID or graduated into remote-first workplaces where organic socialization — the water cooler, the campus quad, the bar after work — had either disappeared or become logistically complicated. Digital social life, meanwhile, offered connection in form but often failed to deliver it in feeling.

Fitness studios, it turns out, fill that gap with remarkable precision. They are one of the last remaining spaces in American life that are structured, recurring, and built around physical presence in a shared space — the exact conditions that researchers have found most reliably produce genuine human connection.

This is why the feeling of finishing a hard spin class beside a stranger who was also gasping for air can produce a surprisingly warm sense of kinship. It’s not just politeness — it’s neurobiological. And Gen Z, consciously or not, is gravitating toward the environments that deliver it.

The Run Club Renaissance

Perhaps no phenomenon illustrates this better than the explosion of run clubs across American cities. A few years ago, run clubs were the domain of serious competitive runners — small groups organized by pace, meeting at dawn, focused on training metrics. Today, they are a full-blown social institution.

Clubs like November Project (which operates in dozens of cities), New York’s Bridge Runners, Chicago’s South Side Run Club, and hundreds of independently organized groups have transformed running into a community activity. Many don’t even track pace. They show up, they move together, they get coffee or beers afterward. The run is almost incidental.

Strava, the fitness tracking app, reported a 57 percent increase in club memberships among users aged 18–26 between 2022 and 2024. Meanwhile, running specialty retailers have noted that younger customers increasingly cite “social reasons” as their primary motivation for taking up running — a departure from the traditional answers of weight loss, cardiovascular health, or stress relief.

How Boutique Studios Became the New Social Clubs

The fitness industry has not missed this moment. Over the past three years, a wave of boutique fitness brands — some established, many new — have aggressively repositioned themselves not as workout facilities but as communities. The language has shifted. The design has shifted. Even the business models have shifted to encourage regulars, reward loyalty, and foster the kind of familiarity that makes members feel they’re part of something.

Barry’s Bootcamp, which has long cultivated a cult following, has doubled down on its “tribe” aesthetic, with red-lit rooms, instructor personalities that function almost like personalities rather than service workers, and post-class rituals that keep people lingering. Solidcore, the brutal Pilates-on-steroids brand that counts D.C. and New York professionals among its devotees, has built a reputation not just for intense reformer workouts but for the tight-knit regular communities that form around specific class times and instructors.

F45, the Australian-born functional training franchise, explicitly markets itself as a “team training” experience. Life Fitness, the equipment giant, has reported that gyms requesting social-format equipment and layouts — less isolated machines, more open-floor group zones — has increased substantially year-over-year since 2022.

The Instructor as Community Anchor

One of the underappreciated drivers of this shift is the role that fitness instructors now play in Gen Z’s social ecosystems. For many young people, their SoulCycle instructor or bootcamp coach is someone they see more consistently than most of their friends — and whose energy and personality significantly shapes their week.

This is not a casual relationship. Studies on parasocial bonds and group exercise have found that the instructor-participant dynamic in group fitness creates measurable increases in motivation, emotional wellbeing, and — critically — social identity. “I’m a Barry’s person” or “I run with Brooklyn Track Club” has become a genuine social identity marker in the way that “I’m a Crossfit guy” was a decade ago, but broader and more culturally mainstream.

When Going Offline Becomes the Point

There is a seeming contradiction at the heart of this trend: Gen Z is the most digitally native generation in history, and yet they are seeking out fitness experiences that are resolutely, emphatically analog. No screens. No algorithms. Just bodies in a room, moving.

But the contradiction resolves quickly when you understand what the constant-connectivity of digital life actually feels like from the inside. For a generation that has spent adolescence and young adulthood navigating social media’s combination of social visibility and emotional distance — being watched without being known, being connected without feeling close — the appeal of a space that offers the inverse is enormous.

Group fitness, at its best, is the opposite of social media. You are present without performing. You are seen without being curated. The feedback you receive — encouragement from classmates, a nod from an instructor, the shared misery of the final set — is immediate, embodied, and real.

This is also reflected in what Gen Z says they want from fitness spaces. Market research from Mintel’s 2024 Fitness Consumer Report found that “sense of community” ranked as the third most important factor for Gen Z when choosing a gym or fitness studio, behind only location and cost — and ahead of equipment quality, class variety, and app integration.

The TikTok Effect: Viral Community, Real World Action

It would be incomplete to discuss this trend without acknowledging the role that TikTok has played in accelerating it — an interesting wrinkle in the “offline” narrative. Run club aesthetics, group fitness “day in my life” content, and the general framing of working out socially as an aspirational lifestyle have flooded the platform over the past two years.

Videos of Brooklyn run clubs with hundreds of attendees, Chicago yoga events in public parks, and Los Angeles outdoor workout groups have racked up millions of views. The content doesn’t just document the phenomenon — it recruits for it, creating a feedback loop where seeing community fitness culture online drives real-world participation, which then generates more content.

In this sense, digital and physical feed each other. TikTok shows the aspiration; the run club delivers the reality. For Gen Z, one doesn’t preclude the other — they’re adjacent parts of the same social ecosystem.

The Access Gap: Not Everyone Gets a Run Club

It would be dishonest to write about this trend without acknowledging its significant fault lines. The social fitness revolution is, so far, disproportionately concentrated among young people in major coastal cities, with college educations and discretionary incomes that make boutique studio memberships financially viable.

A monthly unlimited membership at a boutique fitness studio in New York or San Francisco can cost between $180 and $350. Even “budget” boutique options can run $80 to $120 per month — multiples of what a basic gym membership costs. For the millions of Gen Z Americans working service jobs, living in suburban or rural areas, or managing student debt alongside entry-level salaries, this kind of spend is simply not accessible.

Community-organized run clubs, many of which are free, represent the more democratically available version of this trend. Parks and recreation departments in cities like Denver, Philadelphia, and Houston have responded by funding group fitness programming that doesn’t require a credit card. But the broader boutique fitness boom carries a real risk of becoming another axis of wellness inequality in America — where the social and mental health benefits of community exercise accrue primarily to those who can already afford them.

This is a challenge the industry will need to reckon with seriously if the social fitness movement is to have lasting, broad public health impact rather than simply becoming another luxury amenity for the urban young professional class.

What Comes Next for Social Fitness Culture

The group fitness surge is not a blip. Every indicator — membership data, investment flows, cultural visibility, and the underlying social conditions that created it — suggests it will intensify over the next several years rather than recede.

Several trends are worth watching closely. First, the workplace fitness benefit is undergoing a renegotiation. Remote and hybrid work has eliminated the corporate gym for millions of young workers, and employers are increasingly offering wellness stipends that employees can spend on boutique memberships and run club gear — effectively subsidizing the social fitness experience. Companies like Gympass (now Wellhub) have grown rapidly by packaging access to thousands of fitness options, including group classes, under single-price corporate benefit plans.

Second, outdoor and pop-up group fitness is expanding rapidly. November Project built its entire brand on free, outdoor, weather-optional group workouts — and its model is being replicated in cities across the country. Parks in Miami, Atlanta, and Minneapolis have seen the emergence of informal fitness communities that operate entirely without membership fees, studios, or app subscriptions.

Third — and perhaps most tellingly — the language around fitness is changing in ways that reflect a deeper values shift. “Gains” and “metrics” and “optimization” are giving way to “community,” “consistency,” and “showing up.” The influencer aesthetic of the perfect physique as proof of discipline is losing cultural ground to something messier and more human: the sweaty group photo after a hard class, the shared suffering on a cold morning run, the group chat that forms organically among people who see each other three times a week.

This is not the end of individual fitness goals. People still want to be strong, lean, fast, or flexible. But for Gen Z, those goals are increasingly pursued in community — as if the togetherness is part of the medicine, not a distraction from it.

Because, increasingly, the evidence suggests it is.
