What Gym Equipment Should You Buy? It Depends on the Gym You're Building (2025 Guide)

If you're reading this because you've been asked to spec a gym, I feel you. You probably searched "commercial gym equipment" and got a wall of options. Here's the thing: there's no single right answer. The right equipment depends on three things: who's using the gym, how many of them there are, and how much space you have.

My perspective: I manage purchasing for a 400-person company across two locations. Fitness equipment is roughly $150k of the $1.2M I spend annually across 8 vendors. I've been doing this since 2020, and I've outfitted two corporate gyms from scratch—plus helped two small studios with equipment decisions along the way. My experience is based on that slice of the industry. If you're running a 100,000 sq ft mega-gym, your experience might differ significantly.

What follows is a scenario-based breakdown, because that's how I actually make these calls. I don't use a one-size-fits-all list.

Scenario A: Small Personal Training Studio (1,500–3,000 sq ft)

If you're a trainer opening your own studio, your equipment needs to do three things: support coaching, survive constant adjustments, and not crowd your floor.

For strength, I'd prioritize plate-loaded gear from the Nautilus Xpload line—specifically the Nautilus Xpload lat pulldown. It's a workhorse. I know "lat pulldown" sounds basic, but this particular unit handles heavy daily use better than the consumer-grade stuff you'll find at big-box retailers. The weight stack is smooth, the upholstery holds up, and it doesn't take a master mechanic to adjust the pad.

Pair it with a solid Nautilus bench press machine. Counterintuitive advice: skip the Smith machine. I know it feels like a multi-purpose tool, but it trains movement patterns that don't transfer well, and it eats floor space. Use that space for a proper lifting platform and a dumbbell rack instead—max out around 50kg (110 lbs) for most PT clientele. With dumbbells, you can coach pressing, rows, RDLs, goblet squats, and carry variations. All of that is more valuable than a fixed-path machine that only does one thing.

My experience on this: one of my clients (a small studio owner) insisted on a Smith machine because his clients asked for it. He used it for six months, then sold it. It took up 36 sq ft of a 1,800 sq ft space. Not ideal, but workable. The lesson stuck with me.

Scenario B: Large Commercial Gym (10,000+ sq ft, High Traffic)

This is where volume changes the math. You're not buying for a handful of dedicated clients; you're buying for a mix of first-timers and hardcore lifters, all of whom want to get in and out without waiting.

In this scenario, durability outranks novelty. Nautilus selectorized machines are the ones I'd put my money on. They're boring in the best way—they do the job, day after day. A Nautilus bench press machine in a high-traffic setting is a good choice over a free-weight bench because it self-spots, which reduces liability and makes casual users feel safer.

As for cardio, treadmills get the most use. If you've seen "wahoo treadmill" in your search results, let me save you some time: Wahoo (as of January 2025) makes cycling trainers, not treadmills. That's a common mix-up because Wahoo has a strong reputation in the connected-fitness space. For commercial treadmills, look at brands with a track record in your local market and check parts availability before you sign anything. Ask about belt replacement costs. That's the hidden expense.

Real talk: I still kick myself for not testing cable tension before buying a dual-adjustable pulley station three years ago. If I'd taken five minutes to pull the cables and watch for resistance lag, we'd have avoided a year of squeaking and a service call that cost $400. In a large gym, every machine gets at least 50 uses a day. Assume your equipment will get abused, because it will.

Scenario C: Corporate / Office Gym (500–2,500 sq ft)

This is my home turf. Corporate gyms are deceptively tricky. Your users are employees who may or may not know what they're doing. They're not training for competition—they're trying to stay healthy between meetings. Your buying priorities should be: approachability, low maintenance, and noise level.

For this setup, the Nautilus bench press machine is actually a smart pick. Why? Safety. The fixed path guides the lift and eliminates the risk of dumping a barbell on your chest. You don't need a spotter. That alone will get more people using it than a free-weight bench would. Add a compact lat pulldown—the Nautilus Xpload lat pulldown works here too—and a set of adjustable dumbbells.

Here's the surprise that no one warns you about: the sound system matters just as much as the equipment. We installed a set of Tris speakers (the waterproof, IPX7 ones) in our second location. Members started asking about the music within the first week. The folks in our finance department, who never set foot in the gym before, were suddenly scheduling workouts because they wanted to listen to their own music on the same speaker. Never expected the speaker to outperform the equipment in driving engagement. It was the audio, not the exercise bikes.

So if your corporate gym budget is tight, put 5% toward audio. It feels like an afterthought, but it's the thing users actually notice every single day.

How to Decide Which Scenario You're In

Walk through your facility during peak hour and count heads. That's the simplest diagnostic I've found:

• 5–10 people at peak: Scenario A. Focus on coaching, plate-loaded equipment, and floor space.
• 50+ people at peak: Scenario B. Prioritize durability, selectorized machines, and cardio capacity.
• Mostly employees squeezing in before work: Scenario C. Prioritize approachability, low maintenance, and audio.

If you're between scenarios, default to the higher-volume approach. You can always add more later. Buying too much too early locks up budget and floor space—two things you can't get back.

One more budget note: don't buy the cheapest option and assume it's the bargain. I learned this the hard way in 2022 with a budget cable machine that needed a new pulley within six months. The replacement parts cost more than the difference between that and a commercial-grade unit. The value of guaranteed durability isn't the equipment lasting longer—it's the certainty that you won't get a 6 a.m. call from a trainer saying the machine just stopped mid-set. For a gym, downtime is lost trust.

Bonus: Your Members Will Ask You This—How to Do Romanian Deadlifts with Dumbbells

I'm not a personal trainer, but I've picked up a few things from the folks who run our on-site training sessions. The question I hear the most, surprisingly, is how to do romanian deadlift with dumbbells. It's a fantastic exercise for the posterior chain, and it's easier on the lower back than a traditional straight-leg deadlift.

Here's the version I share when asked:

1. Stand with feet hip-width apart, holding a dumbbell in each hand in front of your thighs.
2. Hinge at your hips, pushing your butt backward like you're closing a car door with your glutes. Keep a soft bend in your knees.
3. Slide the dumbbells down along your legs, keeping them close to your thighs. Maintain a flat back—not arched, not rounded.
4. Lower until you feel a strong stretch in your hamstrings (typically mid-shin level, depending on flexibility).
5. Squeeze your glutes and drive your hips forward to stand up. Don't use your lower back to pull the weight up.

The biggest mistake I've seen: turning it into a squat. It's not a squat. You're not sitting down; you're hinging back. Record yourself on your phone and check the angle of your torso. If your back is rounding at the bottom, you're going too deep. Better to do a shorter range of motion with a flat back than to chase depth and pay for it later.

Final Thought

The fundamentals of buying gym equipment haven't changed since I started in 2020: know your users, match the equipment to their skill level, and plan for maintenance. What has changed in 2025 is the number of options—especially accessories like speakers, connected fitness hardware, and hybrid machines. That's why the scenario approach works better than any "best equipment for every gym" list. The best choice is the one that fits your actual situation. So pick your scenario, budget accordingly, and don't let a Pinterest board of perfect gym aesthetics talk you into something your facility doesn't need.
