We Test Treadmills Year-Round — These Are the Best Machines We’ve Tried

Must read

The single easiest way to build fitness is to make walking or running a part of your workout routine—there’s no lower barrier to entry in the world of athletics, especially for an endurance sport. But bad weather, busy schedules, and expensive gym memberships are all hurdles to getting in your exercise.

That’s when it’s helpful to have your own treadmill, which can offer a slew of workout programs and entertainment features to keep you motivated and moving. Plus, you can’t beat the convenience and safety of jumping on a quality machine in your own basement or garage.

Looking for a more heavy-duty treadmill that can handle higher speeds, longer miles, and more complex training plans? Check out our roundup of the best advanced treadmills, which cost more, but offer more training features and sturdier builds.

The Best Treadmills for 2024

What to Consider

Track Width and Length

If you’ve ever run on a narrow sidewalk, you know how uncomfortable it can be to have limited side-to-side movement. The same goes for treadmills, which can easily trip you up if a stray stride lands you on the side of your treadmill instead of the track.

Your preferred track width will vary based on how closely your feet land to your center of mass, but a good place to start is 20 inches wide, minimum. If you’re walking, this may still be worth considering, but you have much more control over your feet and where they land, so you can opt for a narrower track if saving space is more important.

A problem you likely haven’t experienced in the real world, on the other hand, is running out of front-to-back space to plant your feet. If your treadmill is too short and you have a long stride, you could find your feet slipping off the back of the deck during your toe-offs.

Your minimum track length will vary a little more than width between individual runners, since we all have different heights and stride lengths, but a good baseline is to avoid anything shorter than 55 inches for running and 45 inches for walking.

Speed and Incline

As you climb the price ladder with treadmills, two of the sneakier upgrades you’ll find in nicer models are a stronger motor and more incline adjustment. A stronger motor allows your machine to maintain a higher max speed without slowing down under your weight, and more incline adjustment allows you to spice up the difficulty of your workouts.

The most common max speed on this list is 12 miles per hour—roughly a 5-minute mile—but not everyone needs something with that much oomph. Likewise, incline-adjustable treadmills normally have a max incline anywhere from 12 to 15 percent, which will get you a grade twice as steep as what’s allowed on any major U.S. highway.

If you don’t need or want that kind of variation, save yourself some money and opt for a simpler model with less (or no) incline. But that variety can also turn a monotonous indoor run into something far more mentally manageable if you don’t have other entertainment handy.

Why Trust Us

Runner’s World’s team of editors has been testing, vetting, and nerding out about running gear and tech since 1966. We’ve evaluated everything from running shoes to performance shorts to smartwatches, both in our lab and outside on our daily trots around town. After all, we’re runners too, and we care about having the best gear just as much as anyone else.

Treadmills are an especially major investment—it’s not easy to test several before buying one, especially if you want to forecast long-term performance, which is why our mile-devouring test team does it for you. We have decades of experience running for work and leisure, knocking out quick intervals on our lunch breaks and slogging out long runs on cruddy-weather days atop these machines. And the more time we’ve spent on different models, the more we’ve learned what makes each brand, model, and generation stand out.

How We Test

Every treadmill on this list has been thoroughly evaluated and tested by our team of editors. Several treadmills, like the NordicTrack Commercial 1750 and the Horizon 7.0 AT, have been mainstays in the workout room at Runner’s World HQ for years. Others reside in our editors’ homes. To provide better context for our own experiences walking and running on each model we’ve listed, we also spoke with product managers and engineers to better understand how these mills run under the hood.

Trevor Raab

We frequently spend lunch runs indoors, staring out windows at picture-perfect days, to get a full assessment of how each treadmill performs.

We spent hours assessing all the features of these machines. We’ve walked while listening to music, done long runs while watching movies, and completed included workouts to test the machines’ interactive and studio class functions. We evaluated them on performance, price, comfort, durability, value, and reliability to come up with this list of treadmills that will best serve your needs when you can’t get outside.

Our Full Treadmill Reviews

Best Overall

NordicTrack Commercial 1750 Treadmill

Commercial 1750 Treadmill

Key Specs

Deck Size 20 x 60 in.
Max Speed 12 mph
Max Incline 12%
Max Decline -3%
Programs iFit Library
Motor 3.5 HP

When it comes to bang for your buck, the 1750 has always been one of the best treadmills. It has a high-speed 14-inch touchscreen console and a blissfully quiet incline motor, and it features all of the convenience options you can find on other NordicTrack machines—quick keys to jump to a particular speed or incline with a single tap instead of repeatedly pressing a button, for example.

Better yet, you may not need those speed adjustment buttons thanks to 1750’s enormous touchscreen and its ever-growing library of trainer-led workouts that auto-adjust your speed and incline.

The screen offers more than twice as much real estate as earlier models. We find it’s large enough to see the countryside in Germany, for example, where one tester virtually followed pro Lucy Bartholomew on a gentle trail run. (NordicTrack treadmills also come with a free 30-day trial of iFit, the program we used to access this workout.)

Underfoot, the new 20-by-60-inch deck size is spacious enough for long strides, and the machine’s wide body is stable enough to accommodate heavy impacts. The cushioning is just slightly bouncy out of the box, though you can adjust the firmness yourself to eliminate some of that springiness.


Best Value With Smart Features

Pro-Form Carbon TLX Treadmill

Carbon TLX Treadmill

Pros
  • Higher top speed and incline than Carbon T7
  • More powerful motor
Cons
  • No decline

Key Specs

Deck Size 35.1 x 74.3 in.
Max Speed 12 mph
Max Incline 12%
Max Decline N/A
Programs iFit Library
Motor 3.0 HP

We have always appreciated the value a Pro-Form delivers. The sibling brand to NordicTrack, Pro-Form shares much of the same technology, like the former’s iFit interactive workout programs. You get a free one-year subscription to iFit when you buy one of these treadmills, too.

The Carbon TLX is an updated version of the Carbon T7, which is now discontinued. The machine is still dialed back just a little to keep the price in check, costing less than Carbon T7 at $999. Like the Carbon T7, you get only a 7-inch touchscreen display, but the top speed has gone from 10 to 12 mph, with a horsepower motor that’s now 3.0 HP instead of 2.6 HP.


Best for Streaming Classes

Horizon Fitness 7.0 AT Treadmill

7.0 AT Treadmill

Deck Size 20 x 60 in.
Max Speed 12 mph
Max Incline 15%
Max Decline N/A
Programs 7
Motor 3.0 HP

Instead of locking you into its own training ecosystem, Horizon keyed in on this treadmill’s adjustment features to give you greater control of your workouts. The 7.0 AT has limited built-in training options, but it connects easily to an iPad or Android tablet. That keeps costs in check because there’s no built-in television, and it allows you freedom to take Peloton classes or run using Zwift.

We like the thumb dials mounted chest-high on the hand grips that let you quickly adjust your speed and incline—it feels way more fluid than trying to stab at buttons on a console. It has a surprisingly steady platform, too: We set it up in one tester’s home, and he found that the deck didn’t shake at all, even after months of use. The belt is narrower and shorter than we’d prefer for high-speed running, but it’s an ideal size if you’re jogging or walking. Plus, you’ll appreciate the small profile if you’re setting it up in a small room.

Best Mid-Range

NordicTrack EXP 10i Treadmill

EXP 10i Treadmill

Pros
  • Workout fan
  • Google Maps workout tech
Cons
  • Smaller screen and shorter belt than Commercial 1750

Key Specs

Deck Size 20 x 55 in.
Max Speed 10 mph
Max Incline 12%
Max Decline N/A
Programs iFit Library
Motor 2.75 HP

NordicTrack long offered a “T Series” of treadmills, which were just a step below its “Commercial” line—they had smaller motors and rollers, plus a slightly narrower deck. That saved you hundreds on the cost, but the machines were still strong performers.

Now, the EXP line steps into that role, with the 10i at the top of that range. (The number in the name indicates the size of the touchscreen on the console.) The Commercial 1750 is still our top pick here if you’re training for a marathon or competing in road races, but you can save some cash to put toward new shoes if you can work with scaled-back specs. The 20-inch belt is still plenty wide for walking and jogging, and its 12 percent incline is as steep as the Mount Washington Auto Road, so it packs plenty of power and variety to suit a challenging training regimen.


We awarded this walking pad the best overall under-desk treadmill because it’s simple and effective—it comes pre-assembled and ready to use. We tried it out at our offices and it was easy to move around (especially compared to the full-sized treadmills we recommend here) since it’s lightweight and has wheels on the bottom. While you shouldn’t use this for lots of run training—the max speed is 3.7 mph and the deck is relatively short—it’s a great tool to get walking while you’re otherwise busy working at your standing desk or attending virtual meetings.


Easiest to Store

Pro-Form City L6 Folding Treadmill

City L6 Folding Treadmill

Pros
  • Easy to tuck away between uses
  • Tablet holder for streaming your favorite classes
Cons
  • No side rails to grab

Key Specs

Deck Size 17.5 x 45 in.
Max Speed 8 mph
Max Incline N/A
Max Decline N/A
Programs iFit Library
Motor 1.6 HP

Folding treadmills don’t really disappear—you’re not sliding one into a closet when you’re done with your jog, at least not a standard-sized one. But the City L6 collapses nearly flat and could slip under your bed frame, your desk, or a big couch to save you some real estate in a crowded living space.

Because of its small motor and low top speed, this option is best if you want a machine only for light walking—we say the same for most other treadmills that fit under a desk. Running is doable, but you’re likely not going to get an accurate readout of your speed and distance as the motor slows down under your weight. It still packs a lot of the training tools you can find on Pro-Form’s running treadmills: If you have a tablet, you can connect to the iFit interactive training platform to get coaching, workouts, and virtual walks through scenic locations.


How to Install a Treadmill Safely at Home

Even a light-duty folding treadmill is a very large piece of equipment—one that isn’t going to go unnoticed in the corner of your living room. While most can be tipped and rolled by one person, actually setting one up or moving it to another room (or floor) of your home can be a real challenge. So we spoke with Ed Pryts, Chief Sales Officer at Gym Source, who has been selling treadmills for over 30 years, to learn the most important considerations before you purchase a new treadmill for your home.

  • Check your ceiling clearance by adding 15 inches to your body height. So, if you are 6’0”, you need at least a 7’3” ceiling. Behind the treadmill there should be at least three feet of unobstructed space.
  • Make sure all four contact points of the treadmill are solidly on the floor and that the floor is stable. Positioning a treadmill close to a wall can increase stability.
  • If there’s another apartment or bedroom below the treadmill’s room, adding a treadmill mat will significantly deaden the transmitted noise in these situations.
  • If you’re moving a treadmill into a basement or smaller room, hire experts. But if you insist on DIY, move and install the deck first, followed by the uprights and console. Either way, check the dimensions of the base and make sure you have clearance for tight corners.
  • If possible, dedicate an electrical circuit to the treadmill. Additional appliances plugged into that circuit can lead to a power overload and an inadvertent shutdown.
