Best Non-Folding Treadmills (2024): Don’t Sleep on These Ultra-Sturdy and Powerful Cardio Machines

We’re suckers for a good foldable treadmill here at Garage Gym Reviews, however there is something about a non-folding treadmill that we cannot deny: They are typically heavy-duty and ultra-durable pieces of exercise equipment. That also means treadmills of the non-folding variety have a bigger price tag associated with them. 

While folding models give you back floorspace in your home gym, non-folding models make up for less floorspace with powerful motors and long running decks perfect for both running and sprinting. I’m going to give you a rundown of the best non-folding treadmills we’ve tried and share our insights into each one so you find the machine that is best suited for your fitness goals—whether that’s weight loss or faster running times. 

The GGR expert product testers have tried more cardio equipment than you can imagine: Dozens of exercise bikes, ellipticals, rowers, and treadmills. But when it comes to treadmills, we’ve had our hands on everything from budget models to commercial-grade machines. This roundup is a series of non-folding machines we’ve put to the test with our own sweat and tears. 

We not only test the fitness equipment we write about, we know what we’re looking for, too. We’re a group of certified personal trainers, CrossFit Level 1 Trainers, former college athletes, and nutrition coaches here to help bring you the most accurate information to guide your home gym buying process. We rate each machine from 1 to 5 based on the following factors:

• Customizations
• Durability
• Tech features
• Warranty/Value

Good for: Anyone seeking an incline trainer with up to 40% grade

Best Incline Non-Folding Treadmill

NordicTrack X24 Treadmill

GGR Score: 4

Check Price Save 8% for Black Friday

Product Highlights

* Goes down to a -6% decline or up to a 40% incline * Speed range of 0-12 mph * 24″ swiveling touchscreen * SmartAdjust technology automatically adjusts speed and incline levels during iFIT classes * Powerful 4.25 CHP motor

Pros & Cons

Pros

• Monitor doesn’t wobble even when running at top speeds
• High-quality speakers
• Large belt deck of 60″ x 22″
• Lifetime warranty on the motor
• 400-lb weight capacity
• Monitor has streaming capabilities
• Can create custom, simulated maps with Google Maps

Cons

• Expensive at around $4,500
• Handlebars are a little slippery
• Cushioning could be better
• High step-up height of over 13″
• Weighs over 400 lbs in the box

Bottom Line

The new NordicTrack X24 Treadmill has an impressive incline/decline range of -6% to 40% and features an impressive 24-inch touchscreen monitor with high-quality speakers. It includes several conveniences, like water bottle holders and a cooling fan that adjusts automatically based on the intensity of your iFIT class. However, the $4,500 price tag is steep, and this large, heavy treadmill could be difficult to move around.

The NordicTrack X24 is hefty in every way possible: size, weight, technology, and price. That said, a certain type of  home gym owner (with the willingness to fund the roughly $4,500 machine) will likely not be disappointed. If you are someone who identifies as a serious runner, hiker, hill climber, or triathlete, the X24 might be the right machine for you. This bad boy offers a range from -6% decline all the way up to 40% incline. 

It’s a sturdy machine, it’s got a powerful motor, and top speeds of 12 MPH. The X24 also has an extra set of handlebars that flank either side of the console, so you can safely work on your hill climbing and have the ability to physically hold onto the machine. 

All that and you’ll also get a 24-inch iFIT-enabled touchscreen for a huge selection of on-demand workouts. You can also use Google Maps technology to drop a pin pretty much anywhere in the world and let the auto-adjust technology change your incline and decline depending on the terrain. The iFIT membership will cost an additional monthly fee on top of the initial price of the machine. 

Best Curved Non-Folding Treadmill: TrueForm Trainer 

Good for: Runners looking to improve form and increase speed

Best Curved Non-Folding Treadmill

TrueForm Trainer

GGR Score: 4

Check Price

Product Highlights

• Well-designed treadmill to help refine running form
• Smooth belt
• Expensive, but worth the money
• Not made in the USA

Pros & Cons

Pros

• Curved running surface to promote better form
• Durable frame
• Hefty weight capacity
• Excellent for HIIT and sprints
• 60 percent more affordable than the TrueForm Runner

Cons

• Costs around $3,000
• Non-motorized treadmill
• Basic monitor
• No preset workouts

Bottom Line

The TrueForm Trainer is a unique treadmill designed to help runners improve their form.

The TrueForm Trainer is a unique treadmill featuring a non-folding design and a curved running surface. The TrueForm trainer is a manual treadmill, which means you, as the runner, are creating power and driving the running belt—there is no power cord or motor in this machine.

The TrueForm Trainer design features a shallow curve that can help improve your running gait. According to Coop, GGR founder and OG product tester, “the shallow deck helps you run with a midfoot strike,” which can create a more efficient stride for some runners. 

This type of treadmill is designed for serious runners looking to become faster and more efficient. I would not recommend this treadmill for the casual runner, especially since it’s best used for full-out running and sprinting. It’s much harder to get the belt moving while walking or jogging.

Best Manual Non-Folding Treadmill: Assault Runner Pro

Good for: People looking for a manual treadmill and don’t want to pay top dollar

Best Manual Non-Folding Treadmill

AssaultRunner Elite

GGR Score: 4

Check Price

Product Highlights

Introducing the most powerful and personalized manual treadmill ever created. The brand new AssaultRunner Elite is expertly crafted to meet the specific needs of professional athletes, home gym users, and commercial owners alike.

Pros & Cons

Bottom Line

For a manual, non-folding treadmill, the AssaultRunner Pro comes in at a relatively reasonable price around $3,000. I know that sounds like a lot for a non-motorized machine, but there are many other similar manual treadmills on the market that go for over $6,000. 

The Assault Fitness brand boasts that manual treadmills keep you engaged because you drive the power and determine how hard you’re going to work. That said, manual treadmill training is often harder than running on a motorized treadmill, because your own strength and oxygen consumption drives how fast you can go, rather than the horsepower of the treadmill dictating your speed. 

The AssaultRunner Pro has a basic LCD display, but you can connect your own smartphone or tablet via Bluetooth or ANT+ to track your progress and running metrics with the app of your choice.

Best Non-Folding Treadmill Warranty: Sole TT8 

Good for: Tall or heavy runners looking for both decline and incline variety

Best Non-Folding Treadmill Warranty

Sole TT8 Treadmill

GGR Score: 3.7

Check Price

Product Highlights

• High-end treadmill with a spacious running belt
• Incline and decline grades 
• 2-ply cushioned belt
• 4.0 HP motor 
• 400 lb weight capacity

Pros & Cons

Pros

• High user weight capacity (400 lbs)
• Powerful motor (4.0 horsepower)
• Can do incline and decline training (-6% to 15% range)
• Spacious 22” by 60” running surface

Cons

• Expensive
• Large footprint
• Heavy, not easy to move
• No touchscreen

Bottom Line

The Sole TT8 is a high-end treadmill with many great features you’d expect to see on a treadmill that costs around $2,900. It offers both incline and decline levels, which is something we don't see on treadmills very often.

Sole Fitness gets brownie points for having one of the best warranties offered for home treadmills: Lifetime warranty on the frame, motor, and deck. Plus an additional five-year warranty on electronics and two years on labor. 

The GGR expert testers have not actually tested the Sole TT8, but our team collectively agrees the Sole F63 treadmill is one of the best entry-level machines you can buy for your home gym. 

That said, we think the Sole TT8, being the light-commercial treadmill model offered by the brand, will be well-suited for anyone who plans to log some serious miles. We also like the fact the Sole TT8 has a powerful 4.0 CHP motor, which is sure to keep up with your top speeds and distance runs. 

The powerful motor paired with the impressive 400-pound user weight capacity indicates this machine is heavy-duty and inclusive for heavier users. Tall runners will be happy to know the Sole TT8 has a 60-inch running surface and is equipped with a two-ply belt and a cushioned flex deck to help lessen impact on ankles and knees.

Unlike other Sole treadmills, this machine features a 10-inch touchscreen with an Android processing system where you can navigate built-in workout programs, connect to a heart rate monitor (sold separately), and other basic controls. One feature I like is that there are also speed and incline controls on the console, so you can use the treadmill without relying on just the touchscreen.

Best Non-Folding Treadmill with a Screen: Peloton Tread

Good for: Anyone interested in interactive programming with on-demand classes

Best Non-Folding Treadmill with a Screen

Peloton Tread+

GGR Score: 3.74

Check Price

Product Highlights

• Soft, cushioned treadmill
• Tilting touchscreen
• Can be powered via electric motor or manually
• Incline up to 15%
• 67-inch running deck

Pros & Cons

Pros

• Cushioned slat belt
• 67-inch running space is well above the industry standard
• 32-inch tilting touchscreen
• Can be used as a manual treadmill in "Free Mode"
• Adjustable incline up to 15%

Cons

• Expensive
• Weighs 455 pounds

Bottom Line

The Peloton Tread+ is a luxury cardio machine that features a cushioned slat belt, tilting touchscreen, and the high-quality interactive that made Peloton a household name. The downside: A very steep price tag.

Peloton is known for top-notch interactive programming and high-energy instructors through the Peloton app. The Peloton Tread gives you a large, 23.8-inch built-in touchscreen to navigate through the vast library of on-demand workouts and live sessions. 

The touchscreen also lets you track your progress, heart rate (from your Apple Watch), and where you’re at on the leaderboard during live workouts. The Peloton Tread is known for high-quality sound systems for jamming out to your own music or one of the curated playlists offered during classes. 

In my opinion, this treadmill offers a solid build and is well-suited for fitness tech lovers. If you’re not married to the idea of a high-tech machine with interactive workouts, I’d choose a treadmill that doesn’t rely so heavily on the touchscreen to operate the machine (like the Sole TT8 I mentioned above). There are not many controls that can be navigated off the touchscreen, making this machine dependent on a stable connection to wireless internet.

Other Non-Folding Treadmills We Tried and Researched 

Some other non-folding treadmills that came up in my research include:

• The Sole ST90, which is a fairly new Sole treadmill featuring a unique slat-belt design. None of the other Sole treadmills have a slat belt, so I didn’t choose the ST90 for this roundup because none of our expert testers have tried it yet.
• The Grit Runner by Tru Grit Fitness almost made the list with its budget price tag, however this manual treadmill doesn’t seem as durable as others we’ve tested.
• The NordicTrack X32i was a close contender for the best incline category, but the other model in this series (X22i) made the cut because it has a better price point. 

How We Picked and Tested the Best Non-Folding Treadmills

There are certainly a lot of foldable treadmills on the market for home gym owners to choose from, but non-folding treadmills can also be a viable option—you’ll just have to account for the space and the increased budget 

With the exception of the Sole TT8, our product testers have actually tried each of the treadmills that are featured on this roundup of best non-folding treadmills. Here are the factors I used to determine this roundup list: 

• Price range: Non-folding treadmills are typically more expensive than folding treadmills, however this list is a collection of some of the more reasonably priced machines our expert testers have tried. 
• Warranty: Every brand’s warranty is different, so I made sure each product on this list at least meets industry standards. 
• Construction: This is a list of treadmills that didn’t leave our testers feeling shaken around during workouts. 
• Weight limit: Most home treadmills have a maximum user weight capacity of at least 275 pounds. I tried to pick non-folding treadmills that surpass that standard. 
• Deck size: Most non-folding treadmills are pretty big, so each product on this list has around a 60-inch deck to accommodate runners and tall people alike. 
• Display: This list is a mix of high-tech interactive screens and basic LCD displays.  
• Speed range: With a combination of manual and motorized treadmills on this list, I wanted to choose motorized machines that can go at least 12 MPH. 
• Portability: Although no treadmill on this list is not foldable, I tried to choose treadmills that have transport wheels.

Benefits of Non-Folding Treadmill

The main benefits of non-folding treadmills is the added stability because the frame has not been designed to fold or hinge. Non-folding machines are also known for higher user weight capacities due to the heavy-duty solid frame and heavier overall product weight. 

Non-Folding Treadmill Buying Guide

Firstly, create a budget for your non-folding treadmill. It’s important to set a limit, because the non-folding variety of treadmills tend to get pricey. You won’t want to waste your time reading through specs of a treadmill that is three times over your budget. 

Secondly, it’s a good idea to measure your designated treadmill area, because non-folding treadmills are not the best for small spaces. They are typically heavier than folding machines, making it harder to transport from room to room. It will be well worth the time to measure out your designated treadmill area and make sure you have a few feet of clearance on either side and about three feet behind the treadmill belt, according to the National Strength and Conditioning Association (NSCA). 

Lastly, it’s important to decide if you’re looking for a high-tech treadmill with interactive programming or a machine with a basic display. If owning a high-tech machine with on-demand workouts is your priority, that will be good to know before you dive into shopping. 

Manual vs Motorized

There are two types of treadmills that fall under the non-folding category: manual and motorized. Here is a quick rundown of both:

Non-Folding Motorized Treadmill

Motorized treadmills range from budget models to high-end machines. Non-folding motorized treadmills typically have these things in common:

• Sturdy construction
• Long running deck
• Powerful horsepower
• Incline training options
• Good for a variety of paces: walking, jogging, and running

Non-Folding Manual Treadmill 

Manual treadmills are known for being athlete-powered and not requiring an outlet. Here are some quick take-aways about manual treadmills:

• No power source required 
• Reinforces efficient running stride
• Typically low-tech displays
• Potentially higher caloric output to maintain top speeds
• No incline training
