The best treadmills of 2025, tested and reviewed by fitness experts

Deck dimensions: 22″ W x 60″ L | Max incline: 15% | Max decline: 0% | Max speed: 12 mph | Weight capacity: 350 lbs. | Folding: Yes | Warranty: Lifetime frame and motor, 5 years electronics and parts, 2 years labor | Motor: 3.5 CHP | Standout features: Folding, incline, Bluetooth speakers, quick dial controls

From an extensive list of treadmills, the Horizon 7.4 AT emerged as the top pick for its exceptional balance of functionality and value. This treadmill is user-friendly, runs quietly, supports up to 350 pounds and conveniently folds for easy storage. It’s also packed with features including an audio jack and Bluetooth speakers, a USB charging port, a cooling fan, a water bottle holder and an energy saver mode. 

Our tester particularly liked that the machine allows for multiple user profiles. She has two adults (ranging in age from mid-40s to 50s) in her home, along with teens, and she found that everyone was able to create their own profiles and track their own workouts with ease. She noted that this made it easy to track progress, boosting motivation. The built-in heart rate tracker can also sync to running apps like Zwift and the treadmill can connect with Bluetooth to running apps, including Peloton and Studio — meaning you can choose which instructor-led class platform works best for you and your needs. Just use the tablet holder to angle your screen how you like it and follow along with your preferred app.

An Amazon reviewer thinks this treadmill improves on Peloton, saying “Treadmill is great. It arrived on time was packaged safely and we couldn’t be happier with our decision. This treadmill is wider and better than the Peloton Tread. I just couldn’t see paying the extra money for Peloton again. We use this tread without a problem via the Peloton apps. Would recommend and would buy again.”

The 7.4 AT’s thoughtful design also stands out for interval training. Personal trainer Michael Betts, director of fitness at TrainFitness, recommends using treadmills for interval training by alternating between different speeds and inclines. “This keeps workouts interesting and challenges your body in new ways,” he says. However, not all treadmills have quick adjusting controls, which can make interval changes frustrating. 

One unique and appreciated feature of this treadmill is the quick-change dials, which speedily adjust the speed and incline. With a max speed of 12 miles per hour and incline up to 15%, you’re well covered for a multitude of training programs and styles. This is especially true given that the belt is on the larger side for a home treadmill at 22-inches wide and 60-inches long. With a wider, longer belt, you’ll have no problem performing sprints or HIIT-style workouts without the risk of stepping off the side or back. However, our tester did notice the belt can feel a bit sticky when changing to higher speeds, which can take some getting used to.

Furthermore, our tester noted that the 7.4 AT was easy to assemble with quality instructions, which can’t be said of some of the other treadmills on this list. It’s got a durable frame that limits vibration and comes with a lifetime warranty that includes both frame and motor. A 4-year parts and 2-year service warranty are also included.

Deck dimensions: 22″ W x 60″ L | Max incline: 12% | Max decline: -3% | Max speed: 14 mph | Weight capacity: 400 lbs. | Folding: Yes | Warranty: Lifetime motor, 10-year frame, 2-year parts, 1-year basic | Motor: 4.25 CHP | Standout features: 24″ pivoting touchscreen, 10,000+ workout library, streaming platform connectivity, auto-adjusting fan

If you’re a runner with a little more room in the budget, you may want to consider putting down a little extra cash to enjoy the added features of our top pick for runners over $2,000. The NordicTrack Commercial 2450 Treadmill has a wider belt than the ProForm Pro 9000 (at 22-inches wide), matches the incline and decline settings of the more cost-conscious pick and has a significantly higher max speed at a truly impressive 14 mph. Additionally, it’s designed to support up to 400 pounds and has a 4.25 cph motor, offering serious durability and power. 

As if those added features weren’t enough, it also offers access to NordicTrack’s iFit programs, but takes the tech to the next level with a huge 24-inch HD touchscreen and two premium speakers. Whether you’re watching Netflix or exploring the world through iFIT, the Commercial 2450 makes workouts more engaging.

Our tester, who runs regularly and has owned residential treadmills for years, was a big fan of this tread. “I love it! I have been running on treadmills more than outdoors since I was pregnant (and my son is 11). This one offers great shock absorption and fun features that let you do a basic run or follow along with a program,” she says.

It’s also worth noting that the touchscreen pivots, allowing you to follow along with off-equipment classes like yoga or strength training. However, like the NordicTrack X24, you do need to pay for the iFIT subscription to unlock the treadmill’s full suite of smart features and maximize the touchscreen’s potential.

As far as the cost, our tester said it’s more than worth the money if you’re an avid runner. “It’s at a good price point. If you’re looking for something cheaper, you’ll undoubtedly be making certain sacrifices, whether that means belt size, speed, incline, stability or technology. At under 3k, it’s fairly affordable for a treadmill. The one I’ve been eyeing is 8k and I don’t think I would really have to give anything up by going with this lower-priced option.” 

Deck dimensions: 20″ W x 60″ L | Max incline: 12% | Max decline: -3% | Max speed: 12 mph | Weight capacity: 300 lbs. | Folding: Yes | Warranty: 10 years frame, 2 years parts, 1-year labor | Motor: 3.6 CHP | Standout features: iFIT compatibility, 22″ HD touchscreen, fan, shock absorption, EasyLift™ Assist for folding

Treadmills are the machines for runners, helping them train rain or shine, but not all treadmills are created equal when it comes to serious training, and most runners will need to spend a bit more to get the features they really need. That said, budget is important, too. The ProForm Carbon Pro 9000 earns our top spot as the best treadmill for runners under $2,000. It’s a machine that’s truly built for runners, supporting incline and decline ranging from 12% to -3%, has easy-adjusting quick dial controls, a 60-inch belt and access to great programming. Our tester (an avid competitive runner) noted that using the super-responsive touchscreen was easy to use during testing, although unlike some other treadmill models, you do have to adjust the incline manually to follow along with classes.

“A more powerful motor can handle higher speeds and incline smoothly,” explains Betts, which is another major benefit of the Pro 9000 — it can handle anything a serious runner can throw at it due to a 3.6 continuous horsepower. This means the motor won’t overheat as easily with high, sustained efforts, so you’ll be able to work longer with smoother functionality and better durability over time. 

We also noticed how stable and supportive the treadmill is, with fantastic shock absorption and practically no shaking, even at high speeds. “The treadmill has a nice shock system so I did not feel like I was slamming into the base, even at faster paces,” shared our tester. Another huge plus she loved? The easy-folding tech and wheels that make the treadmill a breeze to store away. “The easy-fold feature of this treadmill is amazing. The treadmill has a resist on lowering so it drops down slowly which helps it feel safer to fold up and down.” 

However, the treadmill didn’t live up to many Amazon reviewer’s expectations. People report issues with the touch screen, and some feel it’s too expensive for the value it delivers.

Deck dimensions: 20″ W x 60″ L | Max incline: 15% | Max decline: 0% | Max speed: 12 mph | Weight capacity: 325 lbs. | Folding: Yes | Warranty: Lifetime frame and motor, 3 years mechanical parts, 1-year labor | Motor: 3.0 HP | Standout features: Quickdial controls for speed and incline, integrated adjustable fan, Bluetooth connectivity, USB port, dual media shelves, oversized water bottle holders, connects to Apple and Galaxy watches, Peloton, JRNY, Zwift; includes 2-month JRNY trial

Finding a quality treadmill that doesn’t drain your bank account can feel like searching for a unicorn, but the BowFlex T6 proves you don’t need to spend thousands to get a solid, reliable machine. Priced under $1,000, this treadmill delivers the essentials that most walkers and joggers actually need without overloading you with features you’ll never use. It’s the kind of machine that makes starting a home workout routine feel accessible rather than intimidating.

Our tester, a self-proclaimed “treadmill newbie,” was pleasantly surprised by how user-friendly the T6 is right out of the gate. Her Bluetooth connected immediately, and the control panel was straightforward enough to figure out without needing to dive into the manual first. The standout feature is the Quickdial controls that let you adjust speed and incline with a simple twist while you’re moving. “I love the rolly dials to adjust the incline and speed while you are in motion,” she shared, noting how smooth and easy the transitions felt.

The T6 handles both walking and running with a max speed of 12 mph and a motorized incline that reaches 15% — more than enough for most home users looking to add challenging hill workouts to their routine. Our tester loved the incline range, especially since her neighborhood is flat. “It’s super steady. I don’t even notice the shift to an incline till my butt tells me!” she said. The 3.0 HP motor keeps everything running smoothly and quietly, with our tester noting she barely heard the machine at work.

Another win for this treadmill is its comfort features that enhance the exercise experience without adding unnecessary bulk to the price tag. Our tester raved about the integrated, adjustable fan, which made all the difference during sweaty sessions, and the two oversized water bottle holders that easily accommodate most bottles. The belt felt smooth and comfortable with good support, and the machine remained completely stable with zero vibration even during jogging sessions.

While the T6 isn’t a “smart” treadmill with a built-in touchscreen or streaming classes, it does offer Bluetooth connectivity and can sync with Apple and Galaxy watches, plus it’s compatible with third-party apps like Peloton, JRNY and Zwift. There are nine built-in programs that automatically adjust incline, though our tester noted she preferred the manual controls. For those who want to follow instructor-led workouts, you can prop a tablet on the media shelf and stream your favorite classes.

The treadmill folds for easier storage (though our tester didn’t need to test this feature), and at 76 inches long by 35 inches wide, it’s smaller than many treadmills on the market, making it a solid choice for home gyms with limited space. One small note — our tester’s husband felt the machine seemed “a little cheap,” though she disagreed, saying she felt completely safe and steady throughout her workouts.

For anyone dipping their toes into home fitness equipment, the BowFlex T6 hits the sweet spot. “I was pretty surprised to learn that this treadmill is under $1,000. I have equipment that cost double the amount, but those pieces don’t feel any more high-end at all,” our tester shared. “I think this is a great value for anyone looking for an ‘intro’ treadmill.”

Deck dimensions: 20″ W x 55″ L | Max incline: 10% | Max speed: 10 mph | Weight capacity: 300 lbs. | Folding: Yes (hydraulic, partial) | Warranty: Lifetime frame and motor | Standout features: Bluetooth connectivity for apps and music, quick-dial speed and incline controls, built-in fan, multiple device holders

Budget treadmills often mean big compromises, but the Horizon Fitness T101 Connect strikes an appealing balance between affordability and everyday usability. At around $600, it’s priced for first-time buyers but designed to feel more substantial, with a sturdy build and thoughtful features that make it easy to get moving at home. Our tester appreciated the long 55-inch deck that comfortably accommodates walking or light running without the cramped feel of cheaper models.

Quick-access dials on the handlebars let you adjust speed and incline without fumbling mid-workout, which is especially handy for intervals. The console is straightforward but well laid out, with numbered buttons for direct speed/incline jumps and a strong, three-speed fan that’s surprisingly effective during sweaty sessions. While it lacks a built-in screen, Bluetooth connectivity is a standout perk at this price, letting you stream workouts, music or shows through solid built-in speakers while using your own device.

Storage is decent thanks to a folding frame with hydraulic assist, though it doesn’t collapse fully upright and can still take up some space. The machine also weighs around 180 pounds, so moving it regularly isn’t effortless. Our tester noted that the T101 Connect can shake a bit at higher speeds and has less cushioning than premium models, which may be noticeable for dedicated runners logging lots of miles. Still, for daily walks or light jogs, it delivers steady performance without feeling flimsy.

If you’re looking for an entry-level treadmill that doesn’t skimp on the basics, the Horizon Fitness T101 Connect offers reliable quality, smart design details and app-friendly extras that make it one of the best budget choices for home fitness. Read our tester’s full review here.

Deck dimensions: 20″ W x 60″ L | Max incline: 15% | Max decline: 0% | Max speed: 12 mph | Weight capacity: 325 lbs. | Folding: Yes | Warranty: Lifetime on frame and motor, 3 years on deck/parts, 1-year labor | Motor: 3.0 HP | Standout features: Quick speed dials, Bluetooth speakers, heart rate monitor, USB port, device holder, reading rack

Walking is hands-down one of the best forms of cardiovascular exercise around. In addition to its effectiveness for improving heart health, it’s accessible, affordable and most people can get started without too much fuss. Another benefit? Walkers who want a treadmill to keep their workouts going no matter the weather don’t need all the features that runners may require. This generally means that walkers can get away with paying a little less for a machine that meets their specific needs. 

During our tests, we found the Sole F63 was an excellent option for individuals who are serious about walking (and want a high-quality machine that can stand up to frequent workouts), but who may not want to pay for every feature a runner may require.

This treadmill has a good-sized deck, a max incline of 15% that’s great for adding hill workouts to a routine, a high-quality 3.0 HP motor, an included heart rate-monitoring chest strap and a 325-pound weight capacity. And for any walker who wants to work up to jogging or running, the max speed is more than enough at 12 mph. 

While the Sole F63 doesn’t have every high-tech feature available, it’s got the basics: Bluetooth-enabled speakers and a tablet holder with a USB charging port, so you can stream and use third-party apps to track your workouts or follow instructor-led programs. You also get free access to Sole’s fitness app which provides additional workout options to keep you motivated. 

Our tester, who happens to be a personal trainer, had multiple people put the tread through its paces. She said it worked well for all ages and fitness levels and that it was a “great budget treadmill from a solid brand.” That said, she noted that the tread did start to vibrate at higher speeds (around 9 mph), which is why it may be less suited for runners and better for walkers or those who add jogging on an occasional (more casual) basis. 

The final nice feature for this treadmill is that’s particularly easy to fold thanks to its kick-release mechanism and hydraulics that make lowering, lifting and locking the deck a breeze (which is why it won the top spot on our best folding treadmills list). Bear in mind, if you’re limited on space, the folding mechanism won’t work miracles. As one Amazon reviewer points out, “Don’t expect to save much room by folding the treadmill up (maybe 8 or so sq. feet of floor space max).” However, they also point out, “What the folding DOES allow is much easier mobility for the treadmill. The folding process and rolling process are very easy and don’t require a ton of effort, which is definitely nice. folding feature isn’t just about saving space.”

Deck dimensions: 19″ W x 59″ L | Max incline: 0% | Max decline: 0% | Max speed: Manual (user-powered) | Weight capacity: 397 lbs. | Folding: No | Warranty: Lifetime frame and belt, 7 years moving parts, 2 years labor | Motor: Manual (no motor) | Standout features: Curved slatted belt, 8 levels of magnetic resistance, multiple handlebar positions for varied movements (backward walking, pushing/pulling, lateral work)

Manual treadmills have come a long way from the clunky, awkward machines of the past, and the curved treadmill in particular has become a favorite among serious athletes looking to level up their sprint training and overall conditioning. Unlike motorized treadmills that do the work for you, manual treads require you to power the belt with every step, which means you’re working harder and burning more calories in less time. The Centr x HYROX Perform Tread takes this concept to the next level with a curved, slatted design built specifically for high-performance training.

This treadmill is designed for athletes who want a serious training tool that requires zero electricity (which means you can even set it up outside if you have a covered porch) and can handle intense sprint sessions, HIIT workouts and functional training movements. The curved design makes it easy to accelerate quickly and hit those faster paces, while the slatted belt provides exceptional shock absorption that’s much easier on your joints than traditional belts. Our tester, Yahoo’s senior health editor who has a master’s degree in exercise science and is an exercise physiologist and former fitness center manager with extensive fitness equipment experience, loved the feel of the belt, noting that “having the separate slats and the rubberized surface provides exceptional support and shock absorption, even while sprinting.”

The treadmill offers eight levels of magnetic resistance to adjust the difficulty of your workout, though our tester noted that even at the highest resistance level, the belt moves fairly quickly, which makes it better suited for running and sprinting than leisurely walking. “Ultimately, it’s a treadmill built for athletes who want to be able to sprint,” she says. The multiple handlebar positions are another standout feature, allowing for backward walking and simulated sled pushes and pulls, as well as lateral movements that allow for side slides and other functional training exercises.

One major advantage of manual treadmills is safety — if you stumble or fall, the belt automatically stops since it’s powered by your movement. The Centr tread also features long side rails and multiple hand placement options for added stability and security during high-intensity efforts.

However, this machine isn’t without its drawbacks. At 400 pounds, it’s an absolute beast that’s difficult to move even a few inches, and it doesn’t fold or offer any space-saving features. Our tester also had significant frustrations with assembly, calling it the most frustrating equipment assembly experience of her career. “If you’re going to buy this tread, definitely consider the white glove assembly service,” she advised. The treadmill also isn’t quiet — the rolling sound of the slats is noticeable, so if you’re looking for silent operation, this isn’t your machine.

Perhaps the biggest consideration is the price point. At close to $7,000, it’s a serious investment, and our tester noted she’s seen similar manual curved treadmills on the market for $3,000 to $4,000. That said, the build quality is exceptional, and the slatted belt design is extremely durable with minimal maintenance needs and a long lifespan. If you’re a serious athlete looking for a plug-free, performance-focused training tool that can handle sprint intervals, functional movements and intense conditioning work, the Centr x HYROX Perform Tread delivers on its promise.

Deck dimensions: 22″ W x 60″ L | Max incline: 15% | Max decline: 0% | Max speed: 12 mph | Weight capacity: 375 lbs. | Folding: Yes | Warranty: Lifetime frame and motor, 3 years mechanical parts, 1-year labor | Motor: Not disclosed (covered by lifetime warranty) | Standout features: 16″ HD touchscreen, Quickdial controls , quick-switch interval buttons, JRNY app with 2-month free trial, integrates with Netflix, Amazon, Instagram, Peloton, Zwift, Apple Watch and Samsung Galaxy Watch, WiFi, Bluetooth, fan, extra-wide 22″ belt

Interval training is one of the most effective ways to boost cardiovascular fitness and burn calories in less time, but constantly fumbling with buttons to adjust speed and incline can disrupt your flow. The Bowflex T16 solves this problem with hands-down the best interval training controls we’ve tested, making it ridiculously easy to switch between work and recovery phases without breaking your stride.

The standout feature here is the combination of Quickdial controls built into the handles and screen-integrated quick-change buttons that let you flip back and forth between your current settings and previous settings with a single push. “I give two enthusiastic thumbs up to the speed and incline adjustment options,” our tester shared. “Between the quick dials for small changes and the buttons on the screen for larger adjustments and interval adjustments, all the bases are covered for flexibility.” She particularly loved how you can quickly switch between intervals with the push of a button, making high-intensity interval training sessions feel seamless.

The T16 delivers solid specs across the board with a 12 mph max speed, 15% motorized incline, and an extra-wide 22-inch belt that gives you more room to move compared to standard 20-inch belts. The wider surface is especially helpful if you tend to drift side-to-side during intense efforts or have a wider gait. The belt feels smooth and supportive, and the treadmill remains steady throughout incline adjustments, though our tester noted it’s not quite as sturdy as heavier, non-folding models like the NordicTrack X24.

One of the T16’s biggest selling points is its 16-inch touchscreen and entertainment flexibility. Unlike some competitors that lock entertainment features behind expensive subscriptions, Bowflex lets you access Netflix, Amazon Prime, Instagram and other apps without requiring a JRNY membership. You can follow integrated workouts, create and save your own interval routines or stream your favorite shows while you workout — all without an additional subscription. If you do opt for JRNY (which comes free for two months), you’ll get access to instructor-led workouts and “Explore the World” scenic routes, though our tester noted that these workouts don’t auto-adjust speed and incline like some competitors do.

The T16 also plays nice with other fitness apps and devices. It automatically integrates with Apple Watch and Samsung Galaxy Watch for seamless workout tracking, and you can easily follow along with Peloton, Zwift or other third-party apps using the built-in tablet holder. “I actually appreciate that Bowflex makes this so easy,” our tester noted, comparing it favorably to NordicTrack equipment that doesn’t offer device holders or integrate with apps outside their own iFit platform.

Our tester did experience a couple technical hiccups where the treadmill stopped suddenly mid-workout (possibly related to JRNY app integration), which required unplugging and restarting. At around $2,000, the T16 sits in the mid-range sweet spot. Our tester pointed out that the T6 model offers almost identical features for $1,000 less if you’re willing to sacrifice screen size, but if the larger touchscreen and superior interval controls are priorities, the T16 delivers excellent value for serious interval trainers.

Deck dimensions: 20.5″ W x 57″ L | Max incline: 12% | Max decline: 0% | Max speed: 12.5 mph | Weight capacity: 400 lbs. | Folding: No | Warranty: 10 years structural frame and motor, 1 year all other parts; extended warranty up to 20 years with maintained membership | Motor: 3.5 CHP | Standout features: Pivoting 22″ HD touchscreen, streams Netflix and other apps, gamified workouts, scenic runs, competitive races, instructor-led classes, WiFi/Bluetooth enabled, low deck step-up height, integrated fan

Let’s be honest — running on a treadmill can feel mind numbingly boring (treadmills started out as prison punishment, after all). Staring at a wall while your feet pound the belt isn’t exactly thrilling, which is why so many people struggle to stay consistent with treadmill workouts. The Aviron Victory Treadmill tackles this problem head-on with a massive 22-inch HD pivoting touchscreen that transforms your workout into an entertainment experience.

The standout feature here is the ability to stream Netflix, movies and other apps directly on the large, crisp screen — no need to prop up a tablet or crane your neck to see a TV across the room. Our tester, who happens to be a certified personal trainer, called this a “definite standout” and noted that the treadmill is impressively quiet, allowing her to watch shows without cranking the volume. The entertainment factor was such a huge motivator that she said she’d absolutely continue using it.

But Aviron goes beyond passive streaming. The treadmill offers gamified workouts that turn running into an engaging activity rather than a chore. Games like Fishin’ Frenzy, scenic runs through beautiful landscapes, competitive races against other users, and instructor-led classes provide tons of variety to keep workouts fresh. “The gamified aspect makes running feel fun and less like a chore,” our tester shared. If you’re someone who finds traditional running boring and needs engagement to stay motivated, this treadmill delivers.

The machine itself performs well with a 3.5 CHP motor, speeds up to 12.5 mph, and a 12% motorized incline that automatically adjusts during programmed workouts. The belt offers good shock absorption, making it feel like you’re running on a softer surface, and the ultra-low deck step-up height (just 4 inches!) makes it easy to get on and off. Controls on the handlebars and screen let you adjust speed and incline on the fly.

However, there’s a significant catch: the $29 monthly subscription (billed annually) is required to unlock all the games, competitive races, and coached programs. Without it, you’re limited to Manual Mode and basic metrics tracking, though streaming apps are available without a membership. That’s an important cost consideration on top of the treadmill’s already premium price.

Our tester also noted that there’s a slight lag when trying to hit speed targets during games. The treadmill weighs 242 pounds and doesn’t fold, so it’s a permanent fixture once placed. White glove delivery adds another $300 to the purchase price but is highly recommended given the weight.

If you’re willing to commit to the subscription and want a treadmill that makes workouts genuinely entertaining and engaging, the Aviron Victory is worth the investment.

Deck dimensions: 20″ W x 55″ L | Max incline: 12% | Max decline: 0% | Max speed: 10 mph | Weight capacity: 300 lbs. | Folding: Yes | Warranty: Lifetime motor and frame, 2 years parts, 1 year labor | Motor: 3.0 CHP | Standout features: 3 months free Centr membership for new users, 10″ touchscreen with built-in streaming apps

Not everyone who wants a treadmill is planning to rely on it for long walking sessions or to help train for a marathon. Some people prefer strength training, high-intensity interval training (HIIT) or sport-specific exercise, but still want the convenience of a treadmill to fit in some additional cardio. 

Truly, the Centr Runr-S is a clear winner for anyone who wants to round-out their garage gym for at-home workouts but doesn’t necessarily need every feature that a runner or walker might prefer. For starters, it’s an excellent all-around treadmill that’s incredibly easy to set up and use. The assembly is tool-free and can be done by one person. We also really liked the variety of built-in workouts, from military-style fitness tests to randomized hill climbs. Again, these programs make for an excellent supplement to CrossFit-style home workouts or other strength-training routines. 

With a max incline of 12% and a max speed of 10 mph, it’s going to serve the needs of most people, particularly those who don’t label themselves “runners” in a competitive sense. Likewise, the 300-pound weight limit and 3.0 chp provide for durability and power that will last for years in a home gym setting. 

In addition to the workout programs, the Runr-S is WiFi-enabled and comes loaded with a number of music and video apps to keep you entertained. You can’t download additional apps, and while we were able to mirror a cellphone to the 10″ touchscreen during testing, video content wouldn’t play. However, the treadmill comes with enough built-in media options to satisfy most users.

New users also get three months of free membership to the Centr app, which gives you access to trainer-led classes, nutrition and mindfulness programs — an excellent way to make your treadmill workouts even more effective for your physical and mental health.

You get excellent value in the build quality, too, as the Runr-S is sturdy, easy to fold when not in use and comes with a number of thoughtful safety features. The handrails feature a slightly rubbery texture in certain areas for added grip, though they may feel a bit low for taller users. The display also adds a thoughtful touch by confirming if you really want to jump to max speed when you ramp up the intensity. And as a fun bonus, triggering the emergency stop treats you to a picture of Chris Hemsworth — if that’s your kind of motivation!

One thing to note is the belt is on the shorter side at 55-inches long. This will suffice for average-height individuals and for those who don’t have a longer stride, but may make the tread less suitable for taller people or individuals who engage in sprint training. 

Deck dimensions: 22″ W x 60″ L | Max incline: 40% | Max Decline: –6% | Max Speed: 12 mph | Weight capacity: 400 lbs. | Folding: No | Warranty: Lifetime motor, 10-year frame, 2-year parts, 1-year labor | Motor: 4.25 CHP | Standout features: 24″ pivoting touchscreen, smart workout features

Incline training adds intensity and variety to your workouts, according to personal trainer Josh York, founder and CEO of GYMGUYZ, who adds, “This type of training engages your lower body muscles, making them stronger and more toned.” Boasting a steep 40% maximum incline and a –6% decline, the NordicTrack X24 — our top pick for best incline treadmill — is in a league of its own, delivering a realistic running experience, simulating both uphill and downhill terrains.

The NordicTrack X24’s expansive 24-inch touchscreen offers precise control over speed and incline settings while providing access to streaming apps for music or your favorite shows to keep workouts entertaining while you get your sweat on. With an iFIT membership, you unlock a suite of smart features, including AI coaching and video workouts (our tester preferred the Costa Rica beach runs) that automatically adjust your speed and incline to match the on-screen trainer. However, these premium extras come at a cost — an iFIT subscription runs up to $39 per month. Combined with the treadmill’s already steep price tag, it’s a significant investment for those looking to maximize its features.

With a tank-like build quality, we found the X24 sturdy at all speeds and inclines with minimal vibration. It can support users weighing up to 400 pounds with excellent shock absorption to protect joints, and it has two sets of handrails for extra stability on those tough climbs. This is a big, heavy machine, though, requiring at least two people to set it up — white glove delivery is available at an extra cost in the contiguous U.S. — and taller users with low ceilings need to watch their heads at the steepest incline settings. Our tester is just shy of 6′, and when she kicked the incline up to a full 40%, she said her ponytail would brush the ceiling. 

Our tester (who happens to be an exercise physiologist) says that this is a great, fun tread for athletes who want a way to do hill intervals from the comfort of home, or for hikers who need a way to train inside when the weather is bad. It’s also not a bad option for those who would like a stairclimber but who have low ceilings and can’t fit a taller machine in the home. For the average walker or jogger, though? She admits that it’s probably more machine than most people need. 

One other thing to keep in mind is that the step-up height for this tread is more than a foot high given the extra under-carriage room necessary for the -6% decline functionality. While most people can probably manage it without an issue, those with limited mobility through the hips, knees or ankles may want to take this into consideration before making a purchase. 

Deck dimensions: 20″ W x 57″ L | Max incline: 12% | Max decline: 0% | Max speed: 11.2 mph | Weight capacity: 265 lbs. | Folding: Yes | Warranty: Lifetime tech support, 30 day money back guarantee | Motor: 2.0 HP | Standout features: Fully folding, comes pre-assembled, Bluetooth speakers

Never heard of Feier before? Well, we hadn’t either, until it came time to test treadmills. But this brand came out of the gates swinging with a number of top-notch features at an impressively affordable price.

First things first, the tread comes fully assembled. While our tester noted that it’s heavy and required two people to move it up the stairs to her apartment, once it was where she wanted it, she just had to lift the handles and console and lock them into place and it was ready to use. No confusing or frustrating instructions and no installation fees required. 

It’s also fully foldable and can be stored against a wall, requiring next to no floor space. This makes it perfect for apartment dwellers or those who live in cramped quarters. 

You’d think these space- and time-saving features might limit some of the tread’s functionality (it’s often a give-or-take), but the Feier Star 100 shines in features too. It has a max speed of 11.2 mph (more than fast enough for most people), a 12% incline (rivaling that of most high-quality treads) and offers 36 built-in programs and Bluetooth connectivity so you can connect to and stream your favorite treadmill workouts from other apps. 

Our tester recently ran her first half-marathon and is planning to train for more, and she said she feels confident ditching her gym membership to use this treadmill for her training runs. “The only thing that could make this treadmill better, in my opinion, would be a pivoting touchscreen that allows you to stream news and workouts, though for something like that you’re typically looking at a higher price range and I tend to listen to music anyway,” she said. 

It’s worth noting that the belt on this treadmill is shorter than many of the others we tested at 57-inches. For our 5’4″ tester, the shorter belt worked perfectly, but taller users may find that it feels limiting if they want to lengthen their strides. Also, the maximum user weight is 265 pounds, lower than many of our other favorite treads, so it may not be suitable for larger individuals.
