The Black Friday sale is a perfect time to invest in one of the best treadmills, but which model should you choose? Plenty of options are available on the market, from compact foldable treadmills like Echelon Stride to mammoth running machines with big screens and smart features — such as our favorite NordicTrack x22i, for example. Not to mention, many of the best treadmills come with high price tags, and some models can take up way more space than rowing machines and exercise bikes. But that is where we step in.
A good quality treadmill can be a great investment in your health. Whether you are a novice or a seasoned marathon runner, these exercise machines can be invaluable for boosting endurance and cardiovascular fitness. Running on the treadmill can also improve your body composition, Bianca Grover, an exercise physiologist and personal trainer, told Live Science. More information about the benefits of these machines can be found in our Treadmill FAQs section down below.
At Live Science, we know that buying a treadmill is a big decision, so our testers have tried out lots of different models to help you make the right choice. In our treadmill testing process, we take into consideration price, design, durability, value for money, noise levels and how easy it is to use and set up. We also look at shock absorption, smart features and accompanying apps.

Best overall
The meaty NordicTrack x22i takes the crown — its sturdiness, powerful performance and smart features are hard to match. It is, however, the most expensive treadmill in this guide.
Best on a budget
Compact, foldable and surprisingly sturdy, the Mobvoi treadmill offers great value for money — but it does compromise on the flashy extras and maximum speed.
Best for small spaces
This space-savvy foldable treadmill impressed us with sturdiness and smooth performance, and it comes with an app packed with fun workouts.
Best for high-energy classes
The Peloton Tread is iconic for a reason — this thoughtfully designed treadmill offers some of the best live and on-demand fitness classes out there.
Best incline treadmill
This stylish and durable treadmill can reach up to a 12% incline and 22 km/h of speed, and it is foldable, too — but it does come with a high price tag.

The best treadmill overall
✅ You want a performance-oriented treadmill: Sturdy and powerful, it allows for a wide range of running workouts.
✅ You enjoy fitness classes: There is plenty of great fitness content on the iFit app.
✅ You are tall: This treadmill features a long running belt.
❌ You want something small: It is a beast of a machine, so it will not fit in tight spaces.
❌ You are on a budget: It is the most expensive treadmill in this guide.
🔎 NordicTrack X22i: This beastly treadmill offers an excellent running experience at a premium price — it is quiet, comfortable to use and jam-packed with smart features. ★★★★½
Forget the Peloton Tread, the NordicTrack X22i is one of the best home treadmills we have tested. This meaty machine thoroughly impressed us with its smart features, durability, and unbeatable running performance, which is why we awarded it a rare 4.5-star rating in our NordicTrack X22i review.
Whether you are a beginner or a seasoned runner, this treadmill will keep you coming back for more. With the NordicTrack X22i, you are spoiled for choice with thousands of motivating on-demand workouts, as well as daily live classes (iFit subscription needed), a cinematic 22” HD touchscreen and an impressive -6 to 15% decline/incline range.
With joint-friendly Reflex Cushioning, a meaty 4CHP (continuous horsepower) motor — which is surprisingly quiet — and seemingly limitless iFit virtual content, we could work our way through studio classes, instructor-led virtual routes and off the treadmill training like Pilates or yoga. The only downside to this we found was the screen is a bit hard to see when you are not on the treadmill so we had to rely on audio cues to know what to do next. You can tilt the screen slightly, but it would be good if you could angle it into a more practical position.
Another thing worth mentioning: this is a beast of a treadmill and would be better suited to a garage or home gym than the corner of your living room. The plus side of this monster of a treadmill is it has a 22” by 60” belt, so even our tallest tester (6ft 3”) could enjoy a proper run.
The NordicTrack X22i is not cheap, but it’s definitely one of the best treadmills we’ve ever tried, so if you’ve got the funds, you won’t regret the investment.

Best budget treadmill
✅ You are short on space: It is compact and foldable.
✅ You are on a budget: It costs less than $400.
✅ You want a sturdy machine: This treadmill impressed us with its durable build.
❌ You want the flashy extras: No big touchscreen or dedicated fitness classes.
❌ You want a fast running belt: This treadmill is only for walking and gentle runs.
🔎 Mobvoi home treadmill: This no-frills treadmill impressed us with its foldable design, sturdiness and smooth speed transitions — but it is not suitable for sprinters. ★★★★
A decent treadmill will usually set you back by around $1000, but this budget alternative from Mobvoi is surprisingly powerful and comes in at less than $400. It has a maximum speed of 12km/h, which is ideal if you want to do daily gentle jogs and runs. You can also add or remove the rails on either side of the machine, allowing you to slot it under a desk and use it as a walking treadmill.
At this price, you won't get flashy extras like a dedicated digital running platform with upbeat classes displayed on a HD screen. But there's a handy slot for your tablet or phone at the front of your device, which allows you to watch shows while you workout.
During our Mobvoi home treadmill review, we found the belt sturdy and smooth — a lot of cheaper machines tend to 'jerk' at higher speeds, but that wasn't the case here. We were also fairly impressed with the in-built Bluetooth speakers, which allowed us to blast tunes while we ran. If you prefer a quieter session, then the Mobvoi is great too; it was whisper quiet during our testing period.
You can navigate the different controls on the machine using either the LED dashboard or a handy remote. And because it's so compact, it easily slots underneath a sofa or bed for storage.
We did find the belt felt a little thin and it's quite narrow too, but for this price you can't really complain.

Best treadmill for small spaces
✅ You are short on space: It is compact, foldable, and can fit under a bed.
✅ You enjoy fitness classes: Plenty of engaging workouts on the Echelon app.
❌ You are on a budget: It costs more than $1000.
❌ You want a powerful motor: This treadmill does not offer high speeds.
🔎 Echelon Stride: Compact, solid and packed with smart features, it is a great treadmill for those short of on floor space — and the fitness classes are a treat, too. ★★★★
At $1,299, the Echelon Stride isn't exactly cheap — but it's by far our favorite when it comes to balancing a good set of features with a mid-range price tag. It's the ultimate space-savvy machine, with a compact running belt and fully foldable design — ideal for storing under a bed or behind a sofa. And it seems the saying “good things come in small packages” rings true, with the tread delivering an impressive performance on test (in spite of its diminutive dimensions).
It offers speeds of up to 12mph and incline settings as high as 10%. During our Echelon Stride Auto-Fold Treadmill review, we found the base felt sturdy and secure, with only slight wobbling at the highest paces and gradients, and though it only has a 1.75 horsepower motor the belt moved smoothly with no juddering underfoot.
There is an LED console on the handlebars with several interval sessions of varying difficulty on offer. However, we think it’s well worth investing in the Echelon Fit app which – for a monthly subscription fee – allows you to link the treadmill with your phone or tablet and access a huge selection of engaging classes. During testing, we discovered even those sessions labeled advanced proved on the easier side, but there is a huge selection of on-demand studio classes, live workouts and more to explore.
So, if you’re a running newcomer looking for a compact, affordable option, the Echelon Stride is the best treadmill for you.

Best treadmill for high-energy classes
✅ You want a great running experience: The belt is sturdy but springy and comfortable to use.
✅ You enjoy fun fitness classes: Peloton fitness content boasts great quality.
❌ You are on a budget: It is almost as expensive as the NordicTrack x22i.
❌ You want a space-saving design: This treadmill is not huge, but it does not fold or decline.
🔎 Peloton Tread: This sleek-looking, high-performing treadmill is a great option if you love a heart-pumping fitness class — but it is on the expensive side. ★★★★½
The Peloton Tread is a sleek and well-made treadmill that offers a satisfying running experience for all fitness abilities. It comes in Peloton's signature black and red colors and has a striking minimalist design. During our Peloton Tread review, we particularly liked its wide selection of live and on-demand fitness classes. In fact, we even dare to say that the high-intensity workouts created by the Peloton instructors are some of the best out there. We were also impressed by the machine's fuss-free touchscreen.
Speed and incline dials are positioned on the handrails, so there is really very little to distract you from that shiny display. It doesn't have any kind of base at the front of the tread, so you can run along its full length—useful if you have a particularly long stride.
The machine doesn’t have quite as many features as we'd like to see at this price point, as it's lacking a decline option or in-built fan, both of which you can find in the slightly cheaper NordicTrack model above. You will also need a Peloton app subscription to access those famous virtual classes. All of that aside, it is a satisfyingly compact, stylish and quiet machine for runners of all ability.

Best incline treadmill
✅ You want a performance-oriented treadmill: It boasts a wide range of incline and speed settings.
✅ You are short on space: It is foldable.
❌ You are on a budget: It costs well over $2000.
❌ You want excellent connectivity: This treadmill may come with some minor tech issues.
🔎 ProForm Pro 9000: With impressive speed and a wide incline range, this sturdy treadmill will truly put you through your paces — but it does not come cheap. ★★★★
ProForm has taken a minimalist approach to design with the ProForm Pro 9000, using a black and silver palette that gives the tread a slick and subtle look. There’s nothing subtle about the size or price tag of this model though, so you will need some cash and space to house it. However, it is a worthy investment. During our ProForm Pro 9000 review, we were particularly impressed by its wide range of incline settings and foldable design.
The 9000 comes complete with inbuilt dual speakers, fans, and iFit capability which provides access to a vast array of workouts and classes from top-notch coaches and trainers in the game. The 22” eye-catching crisp color touchscreen display will certainly suck you in, and with so much workout choice available, this tread can quench the thirst of even the fittest of running fanatics. The speed and incline quick controls are splashed across the dashboard to offer fuss-free on-the-go adjustments, and you can choose between -3% to +12% incline/decline, as well as up to 22 km/h of speed – all of which can be automated by your trainer during workouts.
While this treadmill does offer an immersive training experience, we found some of the tech tricky to master when we tried it out. There are a couple of tech fixes that could make this model more competitive for the top spot, especially when pitched against models like the NordicTrack X22i.

Best treadmills for home use: Frequently Asked Questions
Are treadmill calorie counters accurate?
Put simply, not quite. Treadmill calorie counters are only really estimating your total calorie burn and the number quoted is most likely to be inaccurate, because it doesn’t take into account the multiple variables that affect its total — including age, gender, height, body composition and fitness level.
However, the calorie estimate is useful for indicating the overall intensity of your session. “Having a general sense of calories burned is always better than nothing,” exercise physiologist Bianca Grover told Live Science. Some treadmills may ask you to put in personal details such as age, weight and height before you start, and this is likely to improve how accurate they are. “They don’t have pinpoint accuracy,” says Grover, “but they are likely closer than those that don’t take this information into account.”
Do treadmills help you lose weight?
To a certain degree, yes. “Treadmill exercises – like any physical activity – require you to burn calories, this can help contribute to your desired daily calorie deficit,” Grover says. However, if you’re looking to decrease your body fat percentage, she advises addressing several other factors alongside upping the amount you’re exercising.
“Treadmills are only one factor in the equation. If you are looking to lose weight, you must be at a consistent caloric deficit, meaning you must burn more calories than you are taking in.” Grover recommends “a safe caloric deficit” of between 200 and 500 calories (per day), with a general goal of losing one or two pounds per week. This will enable your body to slowly lose weight without starving it.
Are treadmill distances accurate?
As treadmill manufacturers are aware of the length of their running belt and the speed at which it is moving, distance-trackers on these machines should be able to provide a good level of accuracy.
“It likely depends on the treadmill, but (in general) they are quite accurate,” says Grover, adding: “Keep in mind that they will certainly feel different than running outside or on a track. Treadmills usually impact things such as length of stride and consistency of terrain.”
Does a treadmill build muscle?
Does running build muscle? To a certain degree, yes. A 2015 study published in Exercise and Sports Sciences Reviews concluded that aerobic exercise, such as running on a treadmill at a moderate speed, “should be acknowledged to increase skeletal muscle mass and be considered an effective countermeasure for muscle loss with advancing age”.
But, while running can increase skeletal muscle mass to some extent, it can’t be used to pack on significant slabs of muscle. If muscle gain (or hypertrophy) is your goal, then strength exercises should be your first port of call. We prescribe hitting the weights and following a program that takes advantage of the progressive overload principle.
What is a good treadmill size?
Treadmill size will depend on the space you have available in your home — a folding treadmill may be a good option if you need to pack the treadmill away after your workout.
Your height and stride length will determine the belt length and width you need, as will the type of workouts you wish to undertake. Keep in mind that the required running space, which you can work out via the treadmill belt size, can also impact the overall footprint of the treadmill. A 22 inch wide belt is usually sufficient for runners, whilst walkers can get away with a 20 inch. If you are over six feet tall, then you’ll want a 60 inch length belt, but if you are under six feet then 55 inch is long enough. If you will be walking exclusively, then a 50 inch belt length is suitable.
What does treadmill warranty cover?
Treadmill warranty will vary depending on the model, but a boilerplate warranty will offer different periods of cover for different parts of the machine: frame, motor, parts and labor.
Treadmill warranties are designed to cover manufacturing defects, as well as potential wear and tear on the machine over time. You should ideally look for frame warranties that are 10+ years, motor warranties that are 5 to 10+ years and parts and electronics that are 1 to 3+ years. Most companies will also have a labor warranty lasting 90 days to 2 years, which covers the cost of the repairman if the machine breaks down in that time. Some brands, like NordicTrack and Proform, have clauses that say storing your treadmill in a garage will void the warranty, as it is potentially exposed to damage in this space.
How to choose the best treadmill for you
Before laying down the cash for a large one-off purchase or committing to a long-term payment plan examine all angles to ensure your treadmill is right for you. Most importantly, consider how you want to use it. "Is it for fitness, performance, rehab, walking? How often do you intend to use it? By being clear on your reason for purchasing the treadmill you will be able to refine your list," Harris said.
For example, this will help you ensure the treadmill’s horsepower (HP) — a measure of energy generated by its motor — meets your needs. "Your training frequency and running dynamics all contribute to the work you will make the 'horse' do and what forces it will be absorbing," Harris said. Generally, treadmills with 1.5 to 2 HP suit most users, but for heavier individuals or those who want to train heavily, treadmills with higher HP are a better option. Being clear on your intended use will also help you pick a treadmill with the right specifications, such as the maximum speed and incline range that suits your training regime, she said.
Another key factor to consider is the dimensions of the treadmill. "Treadmills have a large footprint, and even if you can fit the machine into the designated area, you need enough room to feel comfortable while working out. Take the time to visualize and measure out the space you plan to use," Baldwin said. For example, think of the ceiling height and the height of the person using the treadmill. "A low ceiling plus a high treadmill platform plus a tall person can deem the treadmill unusable, and running folded at the waist is not good for your running form," Harris said. If treadmill size is your main concern, pick a machine that can be folded up and stored out of the way.
Then, consider the overall stability and shock absorption of the treadmill platform. "For instance, rubber slat belt treadmills like those from Woodway, Technogym and Peloton Plus are easier on the body and highly sought after by runners. Some runners even prefer them to running outside," Baldwin said. Also, check the noisiness of the tread. "The manufacturer should state how many decibels the tread produces. Generally speaking, the stronger the motor the quieter the treadmill," Harris said.
If you struggle with motivation or training consistency, you may want to splash out on a treadmill with more advanced features, such as an interactive screen and virtual running environments. "Companies like Peloton have done an incredible job making running fun by creating a virtual community environment," Baldwin said. However, this also means you may need to account for any additional app subscription costs.
Lastly, think of the maintenance necessary to upkeep your treadmill. "Read the fine print and most importantly make sure you know about the warranty and how you are going to maintain your new workhorse," Harris said. Baldwin also stressed the importance of finding a quality treadmill technician. "All treadmills encounter issues eventually, and having professional help available can extend the life of your treadmill for many years," he said.
How we tested these treadmills
How we test the best treadmills
Our reviewers. We know a great deal about the best treadmills — we use them all year round at Live Science. As highly experienced exercise professionals and self-proclaimed fitness fanatics, we know firsthand the many benefits of running. However, we are acutely aware that it is not always feasible to go outside for a jog. Plenty of things can get in the way, from poor weather and time constraints to the lack of good running trails nearby. Treadmills solve all of these pesky issues, helping us to rack up the precious miles without leaving the house. We have tested over two dozen different models over the years, so we know what works and what does not tend to live up to expectations. You can put trust in our verdicts.
We know that everyone has different needs and preferences, which is why we strive to be as objective as possible. We test all treadmills to the exact same standard, either in our purpose-built testing center or in the comfort of our homes. After spending at least a day on each running machine, we rank it across the following categories:
Set-up and usability. In short, we want to know who the treadmill is made for. We assess whether the machine is easy to assemble, move around and store away. We also check the maximum user weight.
Design and display. This is where we look into the treadmill's sturdiness, looks and ease of use. We give our verdict on its controls, display (if there is one), frame and running belt, and we make note of any design tweaks that can enhance the user experience and improve the treadmill's accessibility.
Features. We want to know every single feature of the tested machine. For example, we check how many modes and speed levels the treadmill has to offer. Also, does it come with any smart features? Which running stats does it measure? Can this treadmill be controlled remotely? Does it allow you to participate in on-demand fitness classes or watch tutorial videos? If so, do they require a subscription?
Performance. We put the treadmill through its paces to get a full picture of its abilities. At the very least, we complete a longer run, an intense shorter session, and (where applicable) several workout classes. We also check any claims made by brands, including the machines’ functionality at their maximum speed and incline settings.
Value for money. Finally, we give our answer to the very important question: is it worth your hard-earned money?
After testing, we use these categories to calculate a final score out of five, and decide whether the treadmill deserves a spot in our roundup of the best treadmills on the market.
