It was built to run 50,000 miles and last 20 years. The hotel upgraded their cardio floor. Now it's sitting in a warehouse, barely broken in, going for a fraction of retail. Meanwhile you're about to spend $3,000 on a big-box brand that'll wobble after 18 months.
That's the pre-owned advantage. Commercial-grade equipment is engineered for facilities that run it 8–12 hours a day. When those facilities upgrade, the secondary market gets machines that are barely warmed up — and John inspects every single one before it goes anywhere near your home.
Save 30–70% — and put the rest toward something useful
That's flooring, mirrors, a cable machine you wouldn't have budgeted for. Or just money back in your pocket. Either way, it's a better outcome.
Life Fitness. Precor. Cybex. TechnoGym. At actual prices.
The brands you see in real commercial gyms — not the consumer versions with half the frame weight — available through PreOwnedGym.com at prices that make sense.
John inspects every piece personally. That's not a tagline.
Before anything gets delivered to your Nassau or Suffolk home, it gets inspected, tested, and serviced. If it doesn't pass, it doesn't ship. Simple.
You walk in and lift. John handles everything else.
Delivery, installation, setup — coordinated through FitMovers123. Nobody has ever moved a 400lb commercial leg press and thought "that was fun." That's exactly why the crew exists.
Good for the planet. Better for your budget. Both things are true.
Extending the life of commercial equipment keeps it out of the landfill and keeps money in your wallet. It's the rare win-win that actually holds up under scrutiny.
"A $1,200 commercial treadmill from PreOwnedGym.com vs. a $1,200 brand new big-box machine. Same price. About 15 extra years of lifespan. That's the math."

The Network Behind the Network
iBuildGyms × PreOwnedGym.com Long Island's Authorized Dealer.
When commercial gyms upgrade, hotels refresh their cardio floors, or fitness centers close down, the equipment doesn't disappear. It goes to PreOwnedGym.com — and as their authorized dealer and certified broker partner on Long Island, John is first in line.
That means when you call John looking for a Life Fitness treadmill or a Cybex cable system, he's not googling it for you. He already knows where it is, what condition it's in, and what it should cost. That's a different conversation than anything you'll have at a showroom.
Sourced from real commercial facilities
Hotels, corporate gyms, fitness centers, universities. Equipment that was built for daily punishment, not occasional use.
Every piece passes John's inspection before it ships
If it has a frayed cable, a worn belt, or a wobbly frame, it gets serviced or it gets rejected. What arrives at your Nassau or Suffolk home is ready to use.
Life Fitness, Precor, Cybex, TechnoGym, Matrix — at prices that make sense
Not the consumer-grade versions. The real commercial machines, sourced through the PreOwnedGym.com inventory network, at 30–70% below new retail.
Delivered and installed. Not dropped at the curb.
FitMovers123 coordinates the logistics. The crew brings it in, assembles it, and leaves you with a gym — not a box of parts in your driveway.
Something breaks later? Still John.
Through Gym Tech Fitness, the service relationship doesn't end at the sale. Maintenance, repairs, parts — one call, same guy.
"I'm not just pointing you to a website. I know the PreOwnedGym.com inventory, I inspect the pieces, and I coordinate everything after. One call. Done."
— John Mavros, iBuildGyms
There Is No Bad Lead
Whatever You Need. John Has a Play for It.
The person hunting for one used dumbbell and the corporate facility manager sourcing 40 pieces of cardio equipment are both John's clients. The entry point doesn't matter. The outcome is always the same — a gym that works.
Tight Budget
Build a Serious Gym. Not a Serious Bill.
You've got $3,000 and a spare room. John can get you a pre-owned commercial treadmill, a cable system, rubber flooring, and a squat rack — brands you've seen in real gyms — delivered and installed. Try doing that at a showroom.
💡 A $1,200 pre-owned Life Fitness treadmill outperforms a $1,200 new big-box machine — every single time. Same money. 15 more years.
"I Don't Have Space"
Yes You Do. You Just Have Too Many Holiday Boxes.
John comes in person, measures the actual room — ceiling height, door width, flooring, power access — and designs around what's there. Wall-mounted racks. Fold-away benches. High-efficiency layouts. He's turned single-car garages into commercial-grade gyms with room to park the SUV.
💡 Free in-home consultation anywhere in Nassau or Suffolk. John brings the iPad, scans the room, and builds the 3D layout right there.
Time to Upgrade
Old Gear Out. Better Gear In. John Handles Both Ends.
Already have equipment you want to trade up from? John brokers the outgoing gear through the PreOwnedGym.com buyer network, coordinates the removal through FitMovers123, and sources the new pieces. You don't manage a single contractor — it's one call, start to finish.
💡 Your old equipment has real value. John's buyer network across the Tri-State area means it moves fast — and that money goes back toward your new setup.
Commercial Facility
Hotels. Offices. Schools. Full Floors, Fully Handled.
Managing a hotel gym refresh, a corporate wellness center, or a school weight room? John sources at scale through PreOwnedGym.com, coordinates a full 3D floor plan, and manages installation across the entire facility. The same white-glove service — just a bigger room.
💡 Pre-owned commercial equipment is the obvious call for facilities — same brands your members recognize, at a fraction of what you'd pay for new.

"I am the 'I know a guy' guy. Need flooring? Me. Need a treadmill repaired? Me. Need to move a gym across town? Me. Need to lose 10 lbs while you're at it? Also me. Stop coordinating five different companies. One message. Problem solved."
This is a rotating sample of what's moving through the PreOwnedGym.com pipeline right now. Inventory changes fast — if you don't see what you need, message John anyway. Odds are he either has it, knows where it is, or can find it in the next 48 hours.

Cardio
Pre-Owned Commercial Treadmill
Commercial-grade. Built for facilities that run it 8 hours a day. Inspected, serviced, and cleared by John before it goes anywhere near your basement. This is the machine your gym pays $8,000 for new. You're not paying $8,000.
A full selectorized strength circuit sourced from a commercial facility. The kind of machine your big-box store either doesn't carry or charges three times as much for. Refurbished, tested, and installed by the crew — you just show up and train.
Most people forget about the floor until they've already dropped a 45-pound plate through it. Commercial rubber flooring — the thick stuff, not the rolls from a sporting goods store — sourced secondhand and available at 70% below what you'd pay new. Your joints will thank you.
This isn't a showroom with 200 units collecting dust. John sources specific pieces for specific clients through the PreOwnedGym.com network, and good equipment goes quickly. If you're hunting for something — a brand, a machine type, a price point — message him now. He either has it, or he knows exactly where to find it.
No Showroom. No Commute. John Shows Up at Your Door.
