Level up your walking or running routine

Deck dimensions: 22 x 60 inch | Max incline: 40% | Max decline: -6% | Max speed: 12 mph | Folding: No | Warranty: Lifetime motor, 10-year frame, 2-year parts, 1-year labor | Motor: 4.25 CHP | Standout features: iFIT compatibility, pivoting touchscreen, USB-C charging port, auto-adjusting fan

With the broadest incline range of any treadmill we tested — and built tough enough to handle whatever workout you dream up — the NordicTrack X24 is our pick for the best overall incline treadmill.

It tilts from a steep 40% incline down to a -6% decline, letting you tackle both uphill and downhill terrain without leaving home. The 24-inch HD touchscreen swivels to show your workouts, and if you add an iFIT Pro subscription ($39/month), you can access trainer-led sessions filmed in beautiful locations worldwide. The coolest part? The treadmill automatically adjusts to match the terrain in your workout, so when you head uphill on a mountain trail in Aspen, your machine follows right along with you.

We were thoroughly impressed by the design and quality of the NordicTrack X24. For example, the treadmill features horizontal and vertical handrails to help keep your balance — or even just to hold onto for dear life — during those punishing climbs. If you need to stop in a hurry, there’s an emergency stop button, as well as a safety key that attaches to your clothes with a clip. 

Be warned: This beast weighs 445 pounds and doesn’t fold. While it has wheels, you’ll definitely want to choose a permanent spot for it. And make sure it’s under a high ceiling. The step-up height starts at 13 inches; when fully inclined? Our 6’0″ tester said her ponytail brushed the ceiling. 

Built like a tank, this machine delivers where it counts: it supports up to 400 pounds, offers a cushy running belt and stays rock-solid no matter your speed or incline. It’s admittedly an expensive investment, but one you’ll enjoy for years to come.

If the 40% incline is a bit much for your needs, but you want all the other bells and whistles this NordicTrack offers, you may want to consider our pick for the best smart incline treadmill, the NordicTrack Commercial 2450. 

Deck dimensions: 20 x 60 inch | Max incline: 15% | Max decline: None | Max speed: 12 mph | Folding: Yes | Warranty: Lifetime frame and motor, 3 years mechanical parts, 1-year labor | Motor: 3.0 HP | Standout features: Quickdial controls, integrated adjustable fan, Bluetooth connectivity, connects to Apple and Galaxy watches, Peloton, JRNY, Zwift

Looking for a treadmill that can actually climb without wrecking your budget? The Bowflex T6 earns our Best Under $1,000 spot thanks to a true 15% motorized incline and controls that make mid-workout tweaks feel effortless. Our first-time treadmill tester had an easy start: Bluetooth paired right away, and the quickdial knobs let her easily adjust speed or grade up and down while moving — no hunting for tiny buttons. Incline changes are smooth and nearly silent, and the frame remained steady even when the incline got steep.

You won’t find a built-in touchscreen here, but the T6 syncs with Apple and Samsung Galaxy watches and connects with popular apps including Peloton, JRNY (two-month trial included) and Zwift. The 20″ x 60″ deck size works well for walkers and joggers, and the belt cushioning feels consistent with no buzz or shake, even during uphill efforts.

Comfort touches are thoughtfully done, including an adjustable fan, two large bottle holders, and separate shelves for phone and tablet so you can stream classes or keep stats where you want them. The T6 folds upright, though it doesn’t shrink to a tiny footprint, but the transport wheels make it easy to shift out of the way.

Deck dimensions: 20 x 57 inch | Max incline: 12% | Max decline: None | Max speed: 11.2 mph | Folding: Yes | Warranty: Lifetime technical support, 1-year limited | Motor: 2.0 HP | Standout features: Folds flat and stores vertically, heart rate monitor, wireless charger, low deck height

The Feier Star 100 is the perfect incline treadmill for small spaces due to its compact 5.6′ x 2.6′-footprint and clever folding design. When you’re done running, it can fold flat or stand upright on retractable feet, taking up a mere 3.5 square feet of space against a wall or in a closet.

But there’s more to the Star 100 than its size and foldability. With a sleek LED display, Bluetooth connectivity, safety key and 36 preset workouts that automatically adjust speed and incline, this treadmill delivers the features you need.

Additionally, its low deck height means you can use the full incline range (up to 12%) without worrying about your ceiling height — a common issue with bulkier treadmills.

The tradeoffs are fairly modest: The motor is 2.0 horsepower, and the weight limit is 265 pounds. But with a max speed of 11 mph and 12 degrees of incline, it’s a great choice for anyone looking to maximize their space without compromising their workout.

Deck dimensions: 22 x 60 inch | Max incline: 15% | Max decline: None | Max speed: 12 mph | Folding: Yes | Warranty: Lifetime frame and motor, 5 years electronics and parts, 2 years labor | Motor: 3.5 CHP | Standout features: Bluetooth heart rate monitor with chest strap, rotary dial controls, multiple user profiles, app compatibility with Peloton, Zwift, and Studio

Interval training requires quick transitions between effort levels, and the Bowflex T16 delivers the smoothest, most intuitive controls we’ve tested for alternating between challenging inclines and recovery periods. The standout feature is the combination of handlebar-mounted quickdials for fine-tuning speed and incline, plus screen-integrated quick-change buttons that let you flip back and forth between your current and previous settings with a single tap. Our tester gave this system “two enthusiastic thumbs up,” noting how the seamless adjustments made high-intensity interval workouts feel effortless.

The 15% motorized incline provides plenty of range for hill intervals, and the extra-wide 22-inch belt gives you room to move during intense efforts without worrying about drifting off the sides. The treadmill stays remarkably steady throughout incline adjustments, and the 3.6 continuous horsepower motor handles sustained high-intensity work without any strain. The 16-inch HD touchscreen offers access to JRNY programming (included free for two months, then $29/month), but you can also stream entertainment apps like Netflix and Amazon Prime or connect with Peloton and Zwift for third-party workouts.

While the T16 isn’t as rock-solid as heavier, non-folding models, it folds for storage and features wheels for easy movement. One limitation: JRNY workouts don’t auto-adjust speed and incline like some competitors, requiring manual changes even during guided classes.

We did hit a couple of quirks: During testing, the treadmill stopped abruptly mid-session a few times (likely tied to JRNY integration), and a quick unplug/restart fixed it. Priced around $2,000, the T16 lands in that mid-range “serious but not luxury” bracket. If you’re willing to trade down the screen size and those superior interval controls, the Bowflex T6 offers a very similar experience for about $1,000 less — but for athletes who prioritize interval ergonomics and a larger display, the T16 deserves a close look.

Deck dimensions: 20 x 60 inch | Max incline: 15% | Max decline: None | Max speed: 12 mph | Folding: Yes | Warranty: Lifetime frame and motor, 3-year deck/parts, 1-year labor | Motor: 3.0 HP | Standout features: Heart rate monitor, USB port, device holder, free app access

The Sole F63 offers high-end quality at a mid-range price, making it our top pick for folding treadmills. While often available for around $1,000 during sales, it feels like a premium purchase — its sturdy frame supports users up to 325 pounds, and its generous deck allows more room to run than our fave compact model, the Feier Star 100. 

The control panel and the LCD screen are easy to navigate, with shortcuts for speed, incline and basic preset programs, including hill climbs and interval training. Thanks to Bluetooth, you can stream workouts and music from your favorite fitness or entertainment apps or explore hundreds of classes through the included Sole+ app.

All in all, you’ll get a smooth, comfortable run, even during longer sessions with inclines up to 15%. The belt runs smoothly, with just a slight vibration at top speeds.

Of course, given its winning status, the Sole F63 is also super-easy to fold. Four wheels make it easy to roll into storage, and a kick-release latch lets you securely lower the deck when you’re ready to run.

Deck dimensions: 22 x 60 inch | Max incline: 12% | Max decline: -3% | Max speed: 12 mph | Folding: Yes | Warranty: Lifetime motor, 10-year frame, 2-year parts, 1-year basic | Motor: 4.25 CHP | Standout features: iFIT compatibility, 24-inch pivoting touchscreen, auto-adjusting fan

There’s smart, and then there’s NordicTrack Commercial 2450 smart. This top-of-class treadmill brings a clever trick to home running: As you explore virtual trails through Google Maps, it automatically adjusts its incline and decline to match the real terrain. To complete the immersive experience, the massive 24-inch touchscreen pivots nearly 360 degrees to give you the flexibility to perform exercises on and off the deck.

The tech features don’t stop there. The NordicTrack Commercial 2450 seamlessly syncs with iFIT (a virtual training membership, for an extra cost), which tracks your progress and tailors recommendations to your performance. It even fine-tunes your intensity based on heart rate, helping you optimize your training and hit that cardio sweet spot. 

Under all this intelligence, you’ll find the essentials done right: a powerful 4.25 continuous horsepower motor, a wide 22-inch belt and cushioning that keeps your runs smooth and comfortable. And with a 400-pound weight capacity, it’s built for nearly any user.

Just know that this premium experience comes with a premium price tag (although still lower than our top overall pick) — plus an iFIT subscription comes at an additional cost ($39/month). And while it folds for storage (another feature our top pick doesn’t offer), the machine is big enough you’re not going to want to move it often. If you’re looking for a treadmill that learns and adapts with you, the Commercial 2450 delivers.

Deck dimensions: 20 x 60 inch | Max incline: 12% | Max decline: None | Max speed: 12 mph | Folding: Yes | Warranty: 10-year frame, 2-year parts and motor, 1-year tablet, 1-year labor | Motor: 3.6 CHP | Standout features: iFIT compatibility, 16-inch HD touchscreen, fan, USB-C charging port, easy fold

Serious runners need a treadmill that can keep up, and the Pro-Form Carbon Pro 9000 rises to the challenge. As NordicTrack’s more affordable sister brand, it combines what matters most: a sturdy 3.6 continuous horsepower motor for those long training sessions and a smooth and spacious deck that gives you room to hit your stride. And at 20 inches wide and 60 inches long, the belt is ideal for taking long strides, even if you’re on the taller side. 

The shock absorption? Excellent, according to our tester, striking an ideal balance — softer than road running but firmer than some other treadmills, making it perfect for those who want their indoor training to translate well to outdoor runs. This sweet spot in shock absorption provides a comfortable experience while preventing joint and foot strain during frequent training sessions.

Our tester also loved the Carbon Pro 9000’s quick-adjusting speed and incline controls and the moderate up to 12% incline. The 16-inch touchscreen provides access to iFIT programming (for the $39 monthly fee) and tracks your stats and progress, complete with Bluetooth connectivity for headphones and fitness trackers and built-in speakers.

While it’s a substantial machine, the Carbon Pro 9000 folds to just 44 inches long and 67.5 inches tall when stored. This space-saving design, along with its 350-pound weight capacity and convenient USB-C charging port, makes it an excellent choice for those who want top-tier performance without sacrificing practicality.

Deck dimensions: 22 x 60 inch | Max incline: 15% | Max decline: None | Max speed: 12 mph | Folding: Yes | Warranty: Lifetime frame and motor, 5 years electronics and parts, 2 years labor | Motor: 3.5 CHP | Standout features: Bluetooth heart rate monitor with chest strap, rotary dial controls, multiple user profiles, app compatibility with Peloton, Zwift, and Studio

At $1,800, the Horizon 7.4 AT is an exceptional value pick by packing premium features into a mid-range price point. You get a lifetime warranty on both frame and motor (plus five years on electronics and parts), a powerful 3.5 continuous horsepower motor and a spacious 22-by-60-inch belt that provides plenty of room for intervals and sprint work. The rotary dial controls enable instant, precise adjustments to speed and incline — perfect for HIIT workouts — and the 15% max incline gives you serious hill-training capability.

What makes the 7.4 AT particularly valuable is its versatility and ease of use. Multiple user profiles make it ideal for households where several people want to track their progress, and the treadmill seamlessly connects with popular apps like Peloton, Zwift and Studio, giving you flexibility to choose your preferred training platform. Built-in HIIT workouts provide structure if you want guidance, while the included Bluetooth chest strap and hand-grip sensors offer accurate heart rate tracking. Our tester praised the straightforward assembly process with quality instructions, and the sturdy frame limits vibration even during intense workouts.

The treadmill folds for storage, though it’s heavy to maneuver when folded. The basic screen offers limited features compared to touchscreen models, and our tester noted the belt can feel slightly sticky when changing to higher speeds. However, for the price, you’re getting a durable, well-built machine with a warranty that reflects the manufacturer’s confidence in its longevity.

Deck dimensions: 20.5 x 57 inch | Max incline: 12% | Max decline: None | Max speed: 12.5 mph | Folding: No | Warranty: 10 years frame and motor, 1 year parts (20 years with maintained membership) | Motor: 3.5 CHP | Standout features: 22″ HD pivoting touchscreen, streams Netflix and apps, gamified workouts, competition modes, coached workouts, 300+ Les Mills programs, Cloud Stride cushioning deck, ultra-low 4-5 inch step-up height

If staring at a wall while trudging through incline workouts sounds unbearable, the Aviron Victory transforms hill training into an engaging experience through games, competitions and entertainment. The massive 22-inch HD touchscreen streams Netflix, Hulu, YouTube and other apps directly (no Aviron membership required), but where this treadmill truly shines is its gamified content that actively incorporates the 12% motorized incline into gameplay. Games like Fishin’ Frenzy turn incline adjustments into fishing mechanics — increase incline to cast your line, crank up speed to reel in catches faster — making hill intervals feel like play rather than punishment.

The $29 monthly Aviron membership (billed annually at $348) unlocks the full entertainment experience: Competitive races against other users or robots, “Pros vs Joes” challenges where you race Olympic athletes at their actual paces, over 70 programs and coached Aviron workouts and the entire Les Mills library of 300+ routines. Virtual scenic destinations let you “run” through beautiful landscapes and all of these workouts leverage automatic incline adjustments to match the programming. Our tester loved how the gamification made “running feel fun and less like a chore,” and the super quiet operation means you can watch shows or focus on games without cranking the volume.

Cloud Stride cushioning gives the deck excellent shock absorption, and since it’s low to the ground, getting on and off is effortless. However, at 242 pounds with no folding mechanism, this is a permanent fixture once placed. The display also vibrates noticeably at higher speeds, which can be distracting. At $2,499 (plus $300 for the practically essential white glove delivery), it’s a significant investment that only makes sense if you’re motivated by competition and gaming and are willing to commit to the ongoing membership costs.

Deck dimensions: 22 x 60 inch | Max incline: 15% | Max decline: None | Max speed: 12 mph | Folding: Yes | Warranty: Lifetime frame and motor, 3-year deck/parts, 1-year labor | Motor: 3.5 HP | Standout features: Four transport wheels, USB port, tablet holder, free Sole+ app access

If you’re into combining screen time with workout time, the Sole F80 makes it easy. The 10.1-inch touchscreen supports both screen mirroring from your devices and direct connection to 12 streaming apps like Netflix, YouTube and Amazon Prime Video. The addition of a tablet holder and Bluetooth speakers make catching up on entertainment super easy.

When it comes to workouts, the Sole F80 continues to deliver with 15 incline levels — more range than many other models — along with a top speed of 12 mph. Its powerful motor and heavy-duty frame support high-impact workouts. And, maybe the best part: You get access to the Sole+ app, which offers more than 3,000 guided workouts, no subscription required. 

The F80 shines when it comes to comfort for all body types. Its spacious 22-inch deck provides plenty of elbow room, while the cleverly positioned console lets taller users maintain proper posture during their workout, even while watching shows. Built solid with a 350-pound weight capacity, it’s a machine that suits most users. One caveat: The handrails are shorter than other models and might not be the best option for people worried about walking or running without holding on.

Finally, with a lifetime warranty on the frame and motor, the Sole F80 is an investment built to last.

Deck dimensions: 16.5 x 42.4 inch | Max incline: 9% | Max decline: 0% | Max speed: 7.6 mph | Folding: Yes | Warranty: 2-year extended warranty | Motor: 2.5 HP | Standout features: Doubles as under-desk treadmill, tablet holder, free UREVO app for tracking and workouts

If you’re looking for something more compact and versatile than a traditional treadmill, the Urevo Strol 2S Pro offers an impressive mix of features in a more manageable package. Unlike bulky treadmills, this walking pad transforms from an under-desk walking solution to a compact walking and jogging machine with its clever folding handlebar design.

The nine incline settings let you dial in your preferred challenge level, while the shock absorption system keeps your joints happy during longer sessions. Dual displays show your stats clearly whether you have the handlebars engaged or folded and the included remote control makes adjustments simple when the handlebar is down — perfect for multitasking during walking meetings or TV time.

While its top speed of 7.6 mph won’t satisfy serious runners, it’s more than enough for a solid jog. The handlebar does double duty, providing stability for users who want extra security and transforming the unit from a walking pad to a more traditional treadmill setup.

The sturdy frame and well-cushioned belt held up through weeks of testing. One minor quirk: The pause function resets to the lowest speed instead of remembering your previous pace. And while the unit is heavy for a walking pad, integrated wheels make moving it around more manageable.
