Want to ramp up your training sessions? Try a, well ... ramp, as in an incline treadmill. Using the best incline treadmill for you can boost your cardio fitness, calorie burn and overall strength, all while going easy on your joints. In fact, research indicates walking on a moderate incline offers effective cardiovascular benefits while also minimizing joint stress, making these machines valuable for everyone from older adults working to maintain their health to serious athletes. The gains can be significant. While studies on treadmill walking tend to be small, one study published in BMC Geriatrics found that for older adults, walking on a 10% incline may increase calorie burn by up to 23% while activating more muscles in the legs and core.
"Incline workouts target lower body muscles, specifically [the] quadriceps, hamstrings and calves — making them incredibly effective for building strength and tone," explains Maria Vazquez, head of training at MyWowFit, an online fitness platform. When you walk or run on an incline, your body engages your leg muscles more than on a flat surface. Over time, this increased engagement leads to greater muscular endurance and strength that can make other workouts and daily tasks feel easier.
"Incline treadmills also help people train for outdoor adventures such as hiking, skiing and snowboarding at various elevations and climbs," says Sarah Pope, a personal trainer and group exercise instructor at Life Time Clarendon in Arlington, Va.
Incline treadmills are available in a range of sizes and price points, offering different incline levels, speeds, tech features, integrated programs and more. To help you choose the best incline treadmill for your needs, our team went all in: We consulted fitness experts, including personal trainers, coaches and an exercise physiologist; researched leading treadmill brands; and put 16 incline treadmills to the test to find the best solutions for every budget and need.
Not sure you need an incline treadmill? We tested even more treadmills and walking pads you may want to consider, and we continue to review new models as they become available.
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-year parts, 2-year service | Motor: 3.5 CHP | Standout features: Bluetooth heart rate monitor, fan, media rack, USB charging port
Interval training is based on quick transitions between high and low intensity, and the Horizon 7.4 AT is built for just that. Its rotary controls enable you to instantly switch between speeds and inclines with precision — no fumbling with buttons or losing precious seconds during your intervals. This rapid-response design ensures every sprint, climb and recovery phase hits right on cue.
What really sets the Horizon 7.4 AT apart is its powerful 15% incline range and 12 mph top speed. The treadmill offers tons of options for designing fun and progressively challenging interval workouts. The tread provides a range of built-in HIIT workouts, but you can also sync your treadmill with training apps like Peloton or download the free atZone app to gain access to on-demand classes and scenic routes.
To maximize your interval training, the treadmill offers precise heart rate monitoring with hand-grip sensors and an included Bluetooth chest strap, which syncs with fitness apps to keep you on target during recovery periods.
Of note: While the Horizon 7.4 AT does fold for storage, it's heavy and may be challenging to move.
Dimensions: 80.1" L x 21.8" W x 52.7" H | Type: Magnetic | Product weight: 158 lbs. | Weight capacity: 300 lbs. | Membership required: No | Foldable: No
The NordicTrack RW900 is a well-rounded rowing machine that works for all fitness levels. Its magnetic resistance ensures a smooth, nearly silent ride, making it effortless to hop on and start rowing. In fact, our tester called it "one of the most intuitive pieces of exercise equipment I have ever tried. You really just hop on, log in and hit 'start.'"
Among the machines we tested, the RW900 ranked as one of the most comfortable and stable options. Its sturdy construction, featuring a thick rail and wide, steady feet, prevented any wobbling during workouts. Beyond its ultra-smooth glide, the RW900 offers a full range of motion, complete with pivoting pedals and a soft-touch handle that's comfortable to grip and hold for extended sessions.
For those seeking a smart rowing machine, the NordicTrack RW900 is loaded with impressive tech features. Its standout 24-inch touchscreen — one of the largest available for home rowers — integrates seamlessly with iFit (optional), elevating the workout experience. While this does add another cost — $15 to $39 per month, depending on which membership you choose — it's really where the magic happens.
iFit gives you access to hundreds of on-demand classes that take you through workouts for every fitness level, and it truly is an immersive experience. "The resistance is automated and changes with you as you move through programs, which keeps you on track to build endurance and strength," said our tester, who added that when she changed the resistance of a program, the machine's SmartAdjust feature automatically tweaked the resistance during the workout (and future workouts) based on her adjustments, tailoring each session to her progress.
Deck dimensions: 20 x 60 inch | Max incline: 15% | Max decline: None | Max speed: 12 mph | Folding: Yes | Warranty: Lifetime frame and motor warranty, optional extended warranties | Motor: 3.0 CHP | Standout features: Easy fold, rapid sync motor, Apple Watch connectivity
There's a lot to like about the Horizon 7.0 AT, our top incline treadmill pick for under $1,000. Instead of loading up on fancy features, it nails the basics: a clear LED display, simple controls and smart Bluetooth connectivity. While it may not have many integrated workouts, you can sync the Horizon 7.0 AT with your favorite fitness apps like Peloton and Zwift. And thanks to the Bluetooth speakers, you can queue up your gym playlist, set your phone aside and focus on getting a great workout. We also love that you can simply tap to connect your Apple or Samsung Galaxy watch for fitness tracking.
Just like Horizon's pricier models, you get handy roller dials to make speed and incline adjustments a breeze. The deck tilts up to 15% for tough uphill climbs, and the 20-by-60-inch running surface gives you plenty of room to move. When you're done with your workout, the hydraulic system helps you fold up the treadmill without risking throwing out your back.
On the downside: We found it rather tricky to put the 7.0 AT together. Horizon, however, does offer a white glove delivery for an extra charge ($349) if you prefer the security of professional assembly.
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 inclined treadmill for small spaces due to its compact 5.6 x 2.6 foot size 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 still 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 two horsepower, and the weight limit is 265 pounds. But with a max speed of 11 mph and 12 levels of incline, it's a great choice for anyone looking to maximize their space without compromising their workout.
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 access.
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-the-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 follow your movements, whether you're joining a live class or exploring a new route.
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: 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: 15% | Max decline: 9% | 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 running 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, and the included remote control makes adjustments simple when the handlebar is folded 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.
From motor power to max incline, here's what to look for when choosing the best treadmill for your needs:
A modest incline range works for occasional challenges. But if you plan regular intense climbs to target your quads, glutes, hamstrings and calves, consider models with extended incline ranges — and possibly decline options. Your experience level should also guide your choice. Beginners — and those overwhelmed by option anxiety — often prefer simpler models with straightforward controls. More advanced users might enjoy premium models with varied workouts and streaming options to keep routines fresh.
Treadmills that remain stable at all speeds and inclines during regular use typically start at around $1,000, with premium models ranging from $2,000 to $4,000 — or more. This higher price point reflects quality construction, ensuring better durability and performance than lower-cost models.
A crucial component affecting cost is motor power. Personal trainer Josh York, founder and CEO of Gymguyz, recommends looking for a motor with at least 2.0 to 3.0 horsepower to ensure reliable performance. Betts agrees, adding, "A more powerful motor can handle higher speeds and inclines smoothly," so if you're serious about incline training, ensure your budget covers a treadmill with enough power to match your needs.
Prices increase with advanced technology like expanded multimedia features and smart functionality. Additionally, some models may require a subscription service to unlock full capabilities. Consider both the upfront price and any ongoing costs when making your final choice.
Most treadmills measure about 3 feet (36 inches) wide and 6 to 7 feet (72 to 84 inches) long, though exact dimensions vary by model and incline capabilities. No matter the size, plan for at least 2 feet of clearance on each side — and 6 feet behind the deck — when choosing your treadmill's location.
And remember, incline treadmills have a higher step-up height, which increases further at an incline. To play it safe, add your height plus the deck's maximum incline height, then allow an extra 1 to 2 feet of headroom. Most users need at least 8 feet (96 inches) of ceiling height to exercise comfortably without worrying about close calls with the ceiling.
Most incline treadmills feature integrated workout programs that automatically adjust the incline based on time or distance. These programs are designed to keep your workouts dynamic and challenging. Higher-end models often offer more built-in workouts and smart features, like iFIT's subscription service with thousands of trainer-led workouts and real-world terrain simulations. For manual control, incline treadmills typically have incremental adjustment buttons. Premium models may include quick-access presets or smooth-rolling dials for precise mid-workout changes.
Standard safety features include handlebars for added support, side guard rails to help you maintain proper alignment and emergency stop mechanisms. The most common is a safety key — a magnetic pin attached to a clip that you wear. If you move too far from the console or fall, the clip detaches and the treadmill stops instantly. Some models even feature a clearly labeled emergency stop button on the control panel for quick access.
Following a fatal accident involving a child, Peloton added a rear guard to their Tread+ to prevent objects from being pulled under the belt. Since most treadmills lack this feature, it's imperative to maintain at least 6 feet of clearance behind the deck for safety. Also, if you have children in the house, it's important to consider how to prevent them from using the treadmill without supervision. A treadmill that has a detachable safety key that you can store away from the machine itself is one helpful solution that can help prevent exercise equipment-related injuries.
There are a lot of incline treadmills out there! To help narrow down the best of the best, we consulted fitness experts and evaluated a slew of treadmills based on motor power, belt size, pricing and warranty to assess each model's durability and overall value. Next, we rigorously tested 16 models, assessing their ease of use, comfort, speed, incline adjustability, entertainment features and display quality. We also thoroughly tested smart feature integrations, like touchscreens, built-in workouts, Bluetooth connectivity and fans. We compared notes, double-checked with experts and — voila! — we whittled the field down to our faves to help you select the best incline treadmill for your fitness goals, lifestyle and budget.
Centr Runr-S: While the incline adjustment is slower than expected, possibly limiting its effectiveness for high-intensity interval training, the Runr-S is an excellent value at $1,559. The sturdy construction, incline range of 0 to 12% and wide assortment of integrated workout options make it a solid choice for many. Plus, you get a complimentary three-month Centr digital membership to enhance your training experience.
Peloton Tread+: This premium treadmill comes with a hefty price tag of nearly $6,000 — and you'll have to spend even more to utilize Peloton's All-Access Membership, which includes its renowned workout programming. But the investment brings impressive features: a 0 to 15% incline range adjustable in precise 0.5% increments, an extra-long 67-inch slatted rubber belt, a 32-inch display and a unique manual mode where your movement powers the belt instead of the motor.
XTerra WalkSlim WS300: At under $1,000, the WalkSlim WS300 is worth considering, especially since it provides 10 incline levels and can fold flat to just 8.5 inches for easy storage. The issue? We found that it becomes unstable at higher speeds and incline settings — and the belt tended to catch when the incline was increased.
Egofit Walker Pro: Another walking pad steal at $399, this one is compact with a quiet motor — but its moderate 5% incline is fixed, leaving no room for customization. Another potential drawback: Taller users might find the belt dimensions a bit tight.
Echelon Stride-4S-22: At $1,590, this treadmill delivers a 0 to 12% incline range, low step-up height, easy folding mechanism and a pivoting HD touchscreen. The one bummer? The touchscreen functionality largely requires an Echelon Premier Membership, sold separately at $39/month.
There are lots of benefits to walking or running on an incline treadmill, including:
Increased calorie burn: When you walk or run on an incline, your body pushes against gravity, forcing you to expend more energy and burn more calories. Notably, at least one study suggests that walking at a modest 5% incline increases calorie burn by about 50%. Bump the incline to 10% and calorie burn more than doubles, increasing by about 110% compared to walking on a flat surface. This same-speed-more-results trick is particularly helpful for maximizing your workout over a shorter period of time.
More muscle activation: Walking or running on an incline engages muscles more intensely than flat-surface walking, particularly targeting your posterior chain (glutes, hamstrings and lower back) along with your quads and calves. This increased muscle activation is key for developing strength and toning.
Boost heart health: Incline workouts raise your heart rate more than flat-ground walking, improving cardiovascular fitness. That means regular incline walking or running strengthens your heart and increases blood circulation, helping reduce your risk of heart disease.
Outdoor hills vary in steepness, so you’ll need to adjust your treadmill’s incline to match the specific terrain you're trying to simulate. For help figuring it out, know that moderate hills on a rolling trail start with an incline of around 5% to 10%. But if you're looking to replicate more strenuous inclines, increase your treadmill’s incline to 12% to 15%. Some advanced treadmills also have decline settings, allowing you to simulate walking or running downhill. If you're hoping to copycat the outdoor experience, try a decline of –1% to –3%.
Start conservatively and gradually increase the incline to match your improving strength and endurance. If an incline feels too challenging, don't hesitate to lower it and focus on maintaining proper form. Here's how to choose the right level:
Beginner
Those new to running or incline training should start at about 1% to 2%. This slight increase helps build cardiovascular endurance without overloading muscles while your body adjusts to the intensity.
Moderate
If you're comfortable with flat-terrain exercise, consider starting at 3% to 5%. This range effectively engages your glutes and hamstrings while remaining manageable — ideal for building strength and endurance without hill-sprint intensity.
Intermediate
Got a solid base of endurance and strength? Training for hill running or preparing for a race? If so, an incline between 6% and 10% is ideal. Here, you'll increase muscle activation, particularly in the lower body, and boost both aerobic and anaerobic fitness.
Advanced
For high-intensity training or simulating steep outdoor terrain, a 10% to 15% incline may be more your speed. This is ideal for experienced folks seeking a real challenge that mimics mountainous terrain. Remember, these levels can be very taxing, so use them sparingly to avoid overtraining.
No! In fact, incline training can actually benefit your knees. One small study found that walking at 3 miles per hour on inclines between 10% and 20% reduced stress on the participants' knee joints compared to walking on flat ground. This stress reduction, combined with increased muscle activation in your legs, may help protect your knees and reduce your risk of joint wear and tear and injury over time.
Here are three popular approaches to incline training:
Try your machine's built-in workouts: Many modern treadmills come with preloaded workouts that automatically adjust the incline as you go, making it easy to get started.
Experiment with interval training: To boost your strength and endurance while keeping your muscles engaged, manually alternate between periods of high and low incline. For example, you could walk at a steep incline for 1 to 2 minutes, then lower the incline for a minute to recover. Repeat the cycle for a set duration, like 20 or 30 minutes. This type of workout boosts strength and endurance while keeping your muscles engaged.
Build strength with a pyramid workout: Start at a low incline and gradually increase it while maintaining a consistent speed. Once you reach your peak incline, slowly decrease back to flat ground. This climbing simulation builds strength and cardiovascular fitness.
Whether you're using built-in programs or creating your own routine, it's crucial to warm up before you start — and cool down afterward. And as always, check with your health care provider before starting a new exercise program to ensure it's a good fit for you.
