I was the new monkey at the zoo.

My sudden, unannounced arrival had riled the other males, none more so than the alpha, a burly guy with thick brown hair and a puffed-out chest. Agitated by the presence of a potential rival, he was now strutting about angrily, hoisting heavy objects and grunting monosyllabically. The other males simply steered clear of me, shooting wary glances in my direction.

Having been in this situation before, I knew the dance and tried my best to ease the tension.

”Hey, can I get a spot?“ I asked the alpha. I hoped my admission of vulnerability might reassure him. It didn’t.

”Yeah, right,“ he huffed and turned back to his heavy lifting.

Ah, the first day at a new gym.

That was many years ago, at a stinky little club. It was typical of a dying breed of health club, places where a few big apes—guys who’ve read every back issue of Flex and chugged countless pitchers of Massive Weight Gainer—rule by intimidation. They monopolize the stereo system, cranking their favorite lifting soundtrack—usually AC/DC’s ”Back in Black“—at deafening decibels. They shout things like, ”Push it, you pussy!“ and ”It’s all you, man!“ And, if you’re not one of them, they don’t want you around.

Gyms like that do still exist, and they’re oppressive places for all but the most hardcore of muscleheads. But the nature of health clubs has evolved over the years. More and more these days, the apes are being kept at bay by owners who recognize that the gym is more than just a place to work the body.

At a time when everything from voicemail to e-commerce is making it easier to avoid human contact, the gym is one of the few remaining places where we actually connect with one another. It’s an increasingly important cultural melting pot, often bringing together, in a fairly intimate way, social circles that otherwise might never intersect.

At the best of gyms, we may go to build our muscles, but we grow in ways we might never have expected.

My current gym is a refreshing change from the sweat-soaked iron mills I’ve known over the years. When it opened a few years back, members of several other local clubs cleaned out their lockers and flocked across town. I joined the migration.

My old gym was a loud, cramped, and miserable place. People stepped past each other without speaking, without making eye contact. Located in the same college town as my new gym, the old one attracted its fair share of students and academics, yet it remained largely dominated by locals—cops and construction workers, bartenders and exotic dancers—who generally were slow to warm up to people from other walks of life. The stereotypical tension between town and gown was usually unspoken but nonetheless palpable. Undercurrents of classism and intolerance poisoned the air.

The new gym, in contrast, was big and clean and bright. And from the start, it was clear the owners would set a very different tone. They stuck the stereo in the office and kept the volume at a reasonable level. Their trainers greeted everyone with a smile and spent as much time encouraging the novices as they did pushing the pros.

The new place attracted a mix very much like that at my old gym, but over time a new equilibrium was reached. The muscleheads were still around, but now they seemed out of their element. Many of the less massive members, those who’d seemed so timid at my old gym, suddenly seemed empowered.

I started to notice fascinating interactions. Guys who’d read everything about Yates (that’s five-time Mr. Olympia Dorian) were now swapping dumbbells with guys who’d read everything by Yeats (that’s poet William Butler). It was Burly Man meet Girly Man, so to speak—and more intriguingly, Burly Man meet Burly Girl: The freeweight room—an overwhelmingly male domain at my old gym—was now decidedly coed.

Even the apes seemed liberated.

One day as I took a break between sets, I struck up a conversation with an acquaintance. He was telling me about a sailing trip he’d recently taken and I remarked that I’d just finished reading Sebastian Junger’s sea disaster tale The Perfect Storm.

As we spoke, I noticed this guy was listening in. I recognized him from my old gym. He’d been one of the worst offenders there. A quiet, imposing hulk, he’d often turn up the stereo as if issuing a threat: ”Turn it down—I dare you.“ No one dared.

But now he was listening intently to our conversation, and I could see he wanted to join in. Finally, he did.

”You know what book I’ve been reading lately that’s really good?“ he offered earnestly. ”It’s called The Thornbirds.“

The Thornbirds. Who’d have guessed?

Under the right conditions, a gym can promote a more tolerant community.

Rather than reinforcing divisions, a good fitness club can be a breaker of barriers, allowing us to make connections we probably wouldn’t make in the world outside. At the gym we are freed from the suits and ties, the work boots and lab coats that help us group people by profession or dismiss them as types. In shorts and a tank top, a banker can look very much like a baker—or a biker, for that matter.

Of course, we still size each other up in shorthand. There’s the guy who wears tight Lycra shorts with nothing underneath, the woman who likes to hang upside down from the pull-up bar and do weird twisty things with her body; there’s the couple who pretend they don’t know each other all through their workouts but then leave the gym holding hands.

Engaged in our shared pursuit of good health, we come to know each other—or at least we think we do.

There was this one guy at my gym who always went about his workouts looking sullen. I’d see him most days and nod hello. He’d nod back but then quickly look away. Eventually, I stopped nodding, and so did he.

Then he stopped showing up at all.

A week went by, then another. When he finally returned, I found myself behind him in the line for the water cooler. Feeling the need to make small talk, I asked about this absence.

”Haven’t been in lately, huh?“

”No,“ he confided. ”I’ve been having a pretty tough stretch lately.“ He explained that his mother had just died after a lengthy battle with cancer.

From then on I saw him in an entirely new light; what I’d taken for aloofness may well have been concern, or fear, or sadness. And so too, I imagined, did he see me differently. We went back to nodding hello and never spoke again, but the dynamic between us had changed.

These interactions may not lead to deep friendships, but they are valuable human connections that are becoming easier to avoid. These may not be first-tier friends—the people you’d ask to watch your dog while you’re away on vacation or call for help when your car breaks down—but our connections with them add texture and richness to life at a time when technology seems intent on taking it away
