IN ONE CORNER of Instagram, there are “science-based” trainers who teach you to “optimally” isolate muscle groups like biceps and rhomboids and serratus anterior. In another, there are those who explain why you don’t need to always go your hardest, and how recovery (between sets and workouts) is your ultimate key to gains.

And yes, recovery and “form” are important. But to build muscle and strength, you also must train with intensity and push your limits. And that’s a critical lesson you learn in hardcore weight rooms like Diamond Gym, a bodybuilding haven in Maplewood, New Jersey. In 2026, gyms like Diamond can feel like relics within a wellness landscape that’s all about AI, cold plunges, ring lights, and the perfect Instagram shot. But venture inside, and you’ll learn three concepts that can propel you forward on your fitness journey.

Diamond is an old-school space, a gritty gym with pictures of greats who’ve come through before on the walls, and plenty of starting-to-rust 45-pound plates. And it’s become a social media sensation thanks to the workouts shared by Haddy Abdel and “Unk”, whose clips have amassed nearly five million followers and hundreds of millions of views. These are blood-and-guts sessions that often include burpee “taxes” (that even a delivery driver needs to pay, hill sprints for rule violations, and a level of intensity that’s attracted athletes, influencers and even NFL legend James Harrison.

It’s all very much like Westside Barbell, the revered Ohio powerlifting gym that popularized belt squats and the use of chain resistance. (I trained at Westside for awhile, by the way, and learned plenty of lessons there.) And while Diamond Gym isn’t pushing any new fitness science, it is delivering throwback lessons intensity and fitness community that will help elevate your training.

You Will Be Judged. Just Not for the Reasons You Expect.

Gritty, hardcore gyms can be intimidating to anyone—although really, any gym space (from a CrossFit box to a Pilates studio) can be. When you walk in and see a community of people already connected to a workout protocol, you’ll feel like an outsider. That can leave you wondering if they’re judging your physique and your squat technique and maybe even your outfit.

But there’s a way to beat that. The currency that pays for your spot at any gym is effort. You see that at Diamond. The guy who deadlifts 700 pounds, but could deadlift 800 if he gave his all, will never be respected as much as the guy who gave everything he had to deadlift significantly less.

That’s the same in any gym. Cruising at five miles per hour during a Barry’s class when everyone else is sprinting? You’re not exactly endearing yourself here, either.

Regardless of the gym, being compared to your absolute potential can feel scary—and you’ll want to resist. But this pressure becomes positive if you embrace it, and it’s a key lesson of training in a hardcore gym.

You’re (Very Likely) Much Stronger Than You Think

Watch almost any video from Diamond Gym and you’ll see a bunch of jacked guys surrounding one person hammering out reps. At some point, the weight will start moving more slowly, as the lifter begins struggling. But often, they don’t stop doing reps. Driven by this fitness tribe, the lifter squeezes out another few reps.

It’s incredibly easy to think you’re at your limits when the weight slows down, especially if you don’t have a tribe to push you. But the strength of places like Diamond (and, really, any gym community) is that they can help you truly understand your limits. When you feel yourself straining just a bit and want to relent, with the aid of a spot, you just might find another few reps. And the closer you get to your limits, the more muscle and strength gains you can make.

Legendary Westside founder Louie Simmons once taught me this lesson firsthand during a deadlift workout. I was happy with a 590-pound deadlift. With Simmons guiding me, I finished the workout by pulling 680.

Guys in spots like Diamond see through what you believe is possible and all the excuses you have. That’s the ultimate in workout accountability. Can’t get that? Try to find at least one consistent training partner; they’ll eventually learn your limits and help you squeeze out a few more reps here and there, too.

Your Hard Work (and Suffering) Will Form Unbreakable Bonds

From NFL receiver A.J. Brown to influencer Larry Wheels to a host of bodybuilders, plenty of big names have come through Diamond Gym. And sure, you may think of them as celebs, but when you watch them in action, you see them grimacing and sweating and grunting—just like everyone they’re training with.

Bonds are formed when you sweat with somebody. If you’ve ever played on a high school sports team, you’ve already experienced this. And tough workouts (whether F45 or a Hyrox or Diamond Gym’s fiercest) remind you of this.

When you’re pushing yourself to the absolute limit, you can’t be anything but you. And that means those you’re training with see that real you—and they’re showing you themselves, too. There’s a vulnerability to going hard in a workout—and relationships can form here.

This can help you inside and outside the gym. Inside of it, some of the bonds you form training hard with others will become your “why” when you need it the most. They’ll get you to show up, they’ll get you to push through when it hurts.

And don’t be shocked if some of those who sweated alongside you become your friends when you leave the gym, too. Tough gyms like Diamond have the power to show you who and what you can be when you break through where you believe your limits are now.
