The New Social Club

Sweat Is the New Social Glue

On any given morning in New York’s West Village or Los Angeles’ Silver Lake, the lines outside boutique fitness studios and run clubs increasingly resemble those outside nightlife venues a decade ago.

But the appeal is no longer just physical transformation. It is social. Across major urban centers, workout groups—once a solitary or purely utilitarian pursuit—are rapidly becoming the backbone of new communities, friendships, and even professional networks. In an era marked by digital fatigue and declining traditional social institutions, fitness has quietly emerged as one of the most powerful engines of human connection.

The data underscores the shift. According to a 2024 report by McKinsey & Company, the global wellness market has grown to over $1.8 trillion, with fitness communities and group-based experiences among the fastest-growing segments. Meanwhile, ClassPass reports that nearly 60% of its users now attend classes with a social component in mind, a figure that has doubled since 2019. Strava, the social fitness platform, has seen club participation increase by more than 30% year-over-year, with urban run clubs in cities like New York and Los Angeles driving much of that growth.

This is not merely a trend but a structural response to broader societal changes. The U.S. Surgeon General’s 2023 advisory on loneliness described social isolation as an epidemic, noting that nearly half of American adults report experiencing measurable levels of loneliness. Traditional avenues for connection—religious institutions, civic organizations, even workplaces—have weakened or shifted, particularly in the wake of remote work. As Harvard’s Graduate School of Education has observed, “Young adults today are significantly more disconnected from community institutions than previous generations, creating a vacuum for new forms of belonging.”

Fitness has stepped into that vacuum with surprising efficiency. Unlike many social environments, workout groups offer a built-in sense of purpose, routine, and shared struggle. “There is something uniquely bonding about collective physical exertion,” said Dr. Emma Seppälä, a Yale School of Management lecturer and author on well-being. “It accelerates trust and connection in ways that traditional social settings often cannot.”

In cities like New York, run clubs such as Midnight Runners and Nike’s community-based initiatives have transformed into social hubs, drawing hundreds of participants weekly. In Los Angeles, collectives like November Project and Koreatown Run Club blend fitness with post-run social gatherings, creating ecosystems that extend well beyond exercise. These groups often incorporate coffee meetups, networking events, and even travel experiences, blurring the line between fitness and lifestyle.

Boutique fitness studios are equally central to this evolution. CrossFit, one of the earliest pioneers of community-driven fitness, has long emphasized group identity as a core pillar. Its model—small classes, shared workouts, and communal accountability—has influenced an entire generation of fitness businesses. Today, studios are doubling down on that approach, recognizing that emotional engagement drives retention far more effectively than programming alone.

“Community in fitness isn’t something that can be manufactured with marketing. It comes from creating an environment where people genuinely feel known and valued,” said Brett Ehrlich, owner of Cycle x Strength, an independent studio in Stamford, Connecticut. “At Cycle x Strength, we focus on small details that build connection over time, whether that’s decorating your locker for your birthday or first class, celebrating milestones like 100 or 500 classes or simply having instructors and staff who know members by name. Authenticity matters more than ever. People can tell the difference between a transactional workout and a place where they actually belong.”

Ehrlich’s observations align with broader industry findings. A 2023 report from the Global Wellness Institute noted that community-centric fitness businesses report retention rates up to 40% higher than traditional gyms. The same report highlighted “belonging” as one of the most critical drivers of long-term engagement, particularly among Millennials and Gen Z consumers.

Influencers and entrepreneurs in the space have capitalized on this shift, building large-scale communities that function as both fitness brands and social networks.

Joe Holder, Nike Master Trainer and founder of The Ocho System, has emphasized the cultural dimension of group fitness, stating that “movement is one of the most accessible ways to bring people together, regardless of background.” Similarly, entrepreneur and fitness personality Katie Austin has built hybrid online-offline communities that blend digital engagement with in-person events, reflecting the growing demand for real-world connection.

Even venture capital has taken notice. Investment in community-driven fitness platforms has surged in recent years, with firms backing startups that integrate social features into workouts. According to PitchBook, funding for fitness-tech companies with social or community components increased by more than 25% between 2022 and 2025, signaling confidence in the durability of the trend.

The appeal is not purely social—it is also psychological. Research from Stanford University has shown that individuals are significantly more likely to maintain exercise habits when they feel socially accountable. Group settings create what behavioral economists call “positive peer pressure,” reinforcing consistency and motivation. “Humans are inherently social creatures,” noted Stanford health researcher Dr. Thomas Robinson. “When exercise becomes a shared activity, it taps into fundamental drivers of behavior that go beyond willpower.”

For many participants, the benefits extend far beyond the gym floor. Friendships formed during workouts often translate into broader life connections—dinners, travel, even business partnerships. “My favorite moments in the studio are seeing people who met at the studio making plans to get together outside of it,” Ehrlich added. “When members feel like they’re part of something bigger than just a class, that’s when retention, energy, and word-of-mouth really take off.”

Gamification has further amplified engagement, turning fitness into a shared narrative. Studios and clubs increasingly incorporate challenges, leaderboards, and themed events to foster collective experiences. “We’ve seen members respond really well to light gamification like Bingo challenges or fun community contests tied to events like the Super Bowl,” Ehrlich said. “It gives people shared moments and keeps the energy in the studio high.”

What emerges is a redefinition of what fitness represents in modern urban life. No longer confined to personal health goals, it has become a primary channel for social interaction, identity formation, and community building. In a world where traditional social structures continue to erode, the humble workout group has evolved into something far more consequential: a new kind of third place, where physical effort and human connection intersect.

As the lines between wellness, social life, and even work continue to blur, one conclusion becomes increasingly clear. The future of fitness is not just about getting stronger or faster. It is about belonging.
