NordicTrack X24 Treadmill Review: The New Top Treadmill?

Dimensions/Storability

The NordicTrack X24 is a large, non-folding treadmill. If you want the most training options, you must have room for them. Its dimensions are 69.9” L x 38.1” W x 73.3” H.

To use it safely, you should factor in these dimensions plus a few extra feet surrounding the treadmill’s deck.

Most people shove their treadmill in the corner of the room. If you’re going to do this, make sure the deck has enough space to incline. You might need to position the X24 further away from the wall than other treadmills.

You will also need to factor in the height. When flat, the deck is 14” tall, and when fully inclined, it is 31.5” tall. To ensure your ceiling is tall enough to use the X24, especially at its 40% incline, I would add 31.5” to your height (in inches) and another 6 to 12” to account for your movement when walking and running. (If you plan to run at higher speeds, I would add 12”.)

So, if you’re 6’ (72”), you’ll need a roughly 9’6’ tall ceiling to use the X24. It requires a taller ceiling than most, but it inclines higher than most treadmills.

With great size comes great weight. The X24 weighs 445 lbs when delivered in the box. It does have front transport wheels so that it can be moved, but only some of our team members can; I can’t. Although, I’m slowly increasing the weight in my squats to get there.

But still, the X24 is hard to move.

There isn’t a good area to hold it to lift it, either. It’s best to keep it where you plan to use it. Think of it as a new roommate with its own space. It does take up less floor space than the X32i, so we’re happy to see the overall floor space needed for it was cut down.

Onboard Workouts & Apps

Workout apps are all the rage. NordicTrack has had iFIT on its treadmills and other fitness equipment for years. It is a big aspect of the treadmills. Here is what you can expect with the membership.

iFIT

The iFIT Pro membership available on the X24 gives you access to everything the treadmill’s touchscreen has to offer.

iFIT is a complete training program that requires a monthly subscription. The cost is $39 per month. However, you can purchase one-, two-, or three-year memberships upfront to save on the monthly price.

iFIT has a large library of trainer-led workouts.

There are indoor and outdoor workouts for the treadmill and other equipment. The NordicTrack X24 includes workouts for the treadmill and mat classes for off-the-treadmill training. There are indoor filmed trainer-led workouts filmed in professional studios. A camera faces the instructor; sometimes, other participants surround the instructor.

Where iFIT stands out is the outdoor workouts.

These are filmed on every continent. Beaches, cities, roads, trails, mountains, and more make up the locations. You can hike up mountains in Hawaii and walk through cities in Italy.

The instructor leads you through the location, often discussing the area throughout the workout. These let you explore the world from the comfort of your home, specifically from the X24.

SmartAdjust and ActivePulse

iFIT also has awesome features to help you improve your training experience on the X24. SmartAdjust is where the treadmill automatically adjusts the speed and incline to match the format of the iFIT workout. SmartAdjust uses the instructor’s cues and your previous workout history to make the treadmill adjustments.

iFIT considers your prior workouts to determine an appropriate speed based on your fitness level and previous performance. You can override this and adjust the X24 anytime, but this is a cool feature for hands-free training. The Follow Trainer button also lets you follow what the instructor has specifically programmed regarding speed and incline levels.

The incline will adjust with SmartAdjust to match the terrain of the outdoor workout. So, if you’re running up a hill, the X24’s incline will adjust to match.

ActivePulse is another awesome feature. It adjusts the treadmill to keep you at specific target heart rate zones throughout the workout. To use this feature, you must use NordicTrack’s heart rate armband (sold separately) or a compatible heart rate tracker, like a Garmin watch.

My Apple watch doesn’t connect to much fitness equipment, so I can’t connect it to the X24 to see my heart rate tracked on the touchscreen. Hopefully Apple will make their watches more compatible with fitness equipment in the future.

iFIT also syncs your workouts to apps like Strava, Google Fit, Garmin Connect, and Apple Health for more tracking. I can see my workout history from iFIT in the Apple Health app.

Create Your Own Workouts

You can now create your own workouts in iFIT. These involve setting goals for your time, distance, and calories. You can also set the time, speed, and incline for different intervals.

In these workouts, a track with all your training metrics is shown on the screen, just like in manual mode.

iFIT is still beta-testing some of the features. At the time of writing this, Google Maps weren’t available. This is where you can draw your route on a map, and during the workout, Google Images will display the location on the screen.

We hope Google Maps will return, but we like the fact that we can now create our own standard workouts in iFIT.

Streaming Apps

iFIT now has streaming apps. Currently, Amazon Prime Video, Netflix, and Spotify are available. You’ll need to subscribe to iFIT to access them and then log into your account for each in iFIT. Other subscription training services like Peloton and JRNY offer streaming apps within their subscriptions.

I like how these apps are integrated into iFIT.

I can take an iFIT workout, mute the instructor, and then pull up a Netflix show and stream while taking the class. If I have SmartAdjust on, the X24 adjusts automatically. I recommend keeping the chart of your workout on the screen at the bottom, so you know when the speed and incline changes are coming.

I like having Spotify, too.

iFIT’s music has been my biggest complaint about the training subscription. iFIT uses a Feed.fm feature with preset playlists of songs split into different genre stations. It’s like listening to the radio in the background of your iFIT workout. You can now skip up to 6 songs per station per hour rather than just changing the station to change the song.

But with Spotify, I can listen to music of my choosing. While I wish some of the indoor workouts had music incorporated into them, having Spotify is a nice trade-off.

AI Coach

An AI iFIT Coach feature is coming soon. This is where you can talk with the AI Coach over texts on your phone and create a personalized workout routine. It will recommend specific iFIT workouts based on your goals. We’re excited to try this feature when it’s available. I’ll update this review here once we can test this feature.

Overall, the amount of content available with iFIT makes a subscription worth it to us on the X24.

Onboard Workouts

You can use the NordicTrack X24 Treadmill without an iFIT subscription. However, you will need to create a free iFIT account to access the ten onboard workouts. Some standard workouts and a few featured iFIT trainer-led workouts are available for free.

These workouts aren’t the most seamless to access. The touchscreen and all of the features iFIT offers are really a part of the whole experience when training on the X24. Just keep this in mind. Manual mode is also available with and without connecting the X24 to the internet.

Console

The NordicTrack X24’s console has been upgraded and streamlined a bit. The touchscreen is 24” instead of 32”. We felt like the touchscreen was too big on the X32i. It covered the cup holders, and the handles covered some of the screen.

24” is my favorite screen size.

It’s large enough to see and reach easily without being overly large. The upper handles don’t cover the screen. Plus, the screen now pivots. So, if you’re taking an iFIT treadmill boot camp class or want to follow up on your hike or run with some yoga or strength training, you can easily pivot the screen to the side to see it.

The upper handles block the screen a little bit when it’s pivoted to the side, but it’s nice being able to turn the screen and use it for more training options with iFIT off the treadmill.

The touchscreen and console are pretty tall. I’m short, but the screen is directly in front of my face.

Even Matt doesn’t have to look down at the screen much, unlike other treadmills.

We’re glad to see that the screen has been updated to be faster with a new processor. Unfortunately, technology can feel dated even after just a few years. The screen is responsive to handle all of iFIT’s new features.

We’ve noticed the touchscreen has some glare. We think this is because iFIT is now in dark mode only. So, the glare is more noticeable when you’re scrolling through iFIT’s library or Spotify, which has a dark background. The screen glare isn’t noticeable during bright outdoor workouts or while watching well-lit movies and TV shows.

The soundbar and fans below the screen have been updated. You can change the position of the fan vents, but there are multiple airflow settings. The fan is fairly quiet, and it hits my neck and face. I’m 5’1”. It hits Matt’s chest, and he’s 6’5”. The speakers are also clear, and the volume adjusts to be loud.

The only part of this design I’m hesitant about is the lack of quick-touch adjustment buttons. These buttons have helped to make NordicTrack treadmills very easy and convenient to use. The standard start/stop buttons and the incline and speed buttons are still below the screen. These adjust the speed by a tenth and the incline by 0.5%.

I like all of the changes, for the most part, but I wish these buttons were kept. These buttons are now on the screen to the left and right sides during your workout.

You just have to touch the touchscreen to use them, which can be a little difficult to do while running.

The screen is within reach, but I’d rather have some speed and incline adjustment buttons or dials on the side handles to adjust the levels more quickly.

The cup holders are now accessible on the X24, unlike the X32i, where you had to reach around the screen.

They are a little shallow, but they hold my 40 oz HydroJug. The screen and console are pretty steady. There may be a tiny bit of screen and console shake, but I don’t notice it while using the X24.

There isn’t a device rack, so I just put my phone in a cup holder to keep it nearby. We didn’t expect a device rack since iFIT is a big appeal to this treadmill.

Build Quality

With everything the NordicTrack X24 does, we expected the construction to live up to our expectations, and it does.

The X24 is an impressive and pricy treadmill, but it’s worth its price for everything you can do on it.

Starting with the fact that the X24 has a 400-lb weight limit and lifetime motor warranty, we were impressed before we even set foot on the deck—and rightfully so—with how the X24 performed for us.

Frame

The steel frame sits under the entire deck. The floor frame has beams for more support, and two steel uprights extend from the frame to hold the console.

We like the more rectangular deck and sharper edges of the frame. Together with the all-black design, they make the X24 look sleek.

The side and upper handles are functional for running and inclining.

They are well within reach for all of us, and we range from about 5’ up to 6’5”. There isn’t a front horizontal handle, so keep this in mind. I tend to use the side handles the most for balance and the upper handles when I’m working at an incline from being tired.

Motor

The motor is powerful—it’s 4.25 CHP, the highest DC motor we usually see in home treadmills. DC motors are more commonly found in home treadmills. They are quieter and made for lighter use than AC motors found in commercial treadmills.

The X24 should handle a lot of running for one person and even a whole family. This treadmill was made for distance running and HIIT. You can walk, jog, run, hike, and more on the X24. Considering it goes up to 12 mph, a 5-minute mile pace, this speed will be a sprint for some people, if not a fast running pace for most.

The motor is tucked under the rear of the deck, so you don’t have to worry about hitting a motor hood with your feet. Another motor for the incline and decline is also under the deck.

This motor is for the impressive 40% incline and -6% decline.

We tested the motor responsiveness, which is how long the treadmill takes to adjust from 1 mph up to 12 mph. It only takes 15 seconds. This is faster than the Peloton Tread and Horizon treadmills, which have previously been the quickest to adjust. The NordicTrack 2450 is slightly faster, but only by one second.

If you plan to do interval training and want a treadmill that adjusts quickly, this is it. When I press the buttons, it almost feels like it is adjusting simultaneously.

The X24 isn’t the quietest treadmill we’ve tested. The new Commercial Series treadmills from NordicTrack are quieter, but they don’t offer all of the features the X24 does. Keep in mind that motorized treadmills make noise. Its decibels are around the equivalent of a kitchen exhaust fan on high when it is at its higher speeds.

With how powerful and versatile the X24 is, we didn’t expect it to be as quiet as other treadmills with less power and training capabilities.

We also measured the deck accuracy when fully inclined, declined, and set to 0%. In our testing, we’ve found that most treadmills are slightly inclined when they are set to level 0. The X24 is at a 1% grade when set to 0. This means that you don’t need to worry about inclining the deck slightly to simulate the intensity of running outside.

The incline was pretty accurate at 39.4% versus the 40% max. Once I’m over about 20-30%, I’m not noticing a half-percent difference, and I doubt you will either. Considering other treadmills don’t even come close to this incline, we can live with this tiny difference.

The decline measured at -4.9% versus -6%. Most treadmills don’t offer a decline, so this small difference isn’t a big deal to us either.

The decline is definitely noticeable and beneficial for well-rounded training.

Our test doesn’t factor in deck cushioning, which is the amount of give in the deck when your feet land. This could change the deck’s accuracy and our measurements, so keep this in mind. Overall, the X24 is accurate, and when you’re at 39.4%, it feels like 40, and you can still tell your friends you worked out at a 40% incline on your treadmill.

The X24 has a speed cap when the treadmill is at its full max incline. It goes up to eight mph when it reaches a 16% incline and up to 6 mph at a 25% incline and above. Then, at a -3% decline, the speed caps at eight mph, and it caps at 6 mph at the full -6% decline.

This is for safety. The incline on this treadmill is tough and impossible for most people to run at. Trust me, even with the speed caps, you’ll still be challenged.

Deck

The deck is 22” wide and 60” long, which is our preferred deck length for running. Considering all that the X24 can do, we’re glad it is at least this long and wide.

It looked smaller when we first started testing it, but it measures 22” x 60”.

One thing I noticed is that the console and uprights are positioned further back over the deck than other treadmills, like NordicTrack’s Commercial Series.

This means that when you’re using the X24, you’re walking and running more on the middle of the deck. This is nice for inclining. On the previous Incline Trainers, we felt like we would be positioned at the very top of the deck in order to reach the handles. With the handles and console back, too, we can reach them just fine.

I was nervous about losing some of the length of the deck with this design, but we haven’t had a problem running and fully inclining on the X24.

Matt, who is the tallest out of all of us, with the longest stride, has room.

We were very eager to test the deck cushioning. We haven’t figured out how to quantify the shock absorption in each treadmill deck, but so far, relying on our extensive experience running on all kinds of treadmills from different brands is working.

The previous Incline Trainers, the X32i and X22i, have had the softest deck cushioning out of all of the home treadmills we’ve tested. Even the NordicTrack 2450, 1750, and 1250 have softer deck cushioning than other brands like Peloton, Sole, ProForm, and Horizon.

The NordicTrack X24 doesn’t feel as soft as the previous Incline Trainers, but it is softer than other brands. These treadmills felt pretty bouncy at higher speeds, over 8 to 9 mph. The X24 has been improved to eliminate the extra bounciness when running at higher speeds, so the cushioning feels more consistent. It feels more similar to running on the 2450, which has excellent deck cushioning.

The X24 feels incredibly stable and durable overall, which is what you want when training on a treadmill that inclines up to 40%.

Warranty

NordicTrack includes their standard 10-year frame, 2-year parts, and 1-year labor warranty with the X24. The motor is also now covered with a lifetime warranty. We love the coverage on the motor; it indicates that it is well-powered and well-made.

To assemble the X24, you’ll need two people at a minimum. This is a heavy treadmill, and assembling it out of the box is challenging.

Should You Buy The NordicTrack X24 Treadmill?

If you’re looking for a treadmill to take your training to the next level, then yes. Suppose you want to train on a soft-cushioned premium treadmill with the highest incline, yes, again. If you love iFIT and want the most training options when you follow along with the instructors, definitely yes.

If you’re looking for a budget treadmill, this one isn’t it. The NordicTrack X24 is at the top of the brand’s lineup. It has a large, rotating 24” touchscreen; the 40% incline and -6% decline are unreal. It’s worth its price. No other treadmill we’ve tested inclines as high. Plus, in our testing, the X24 held its own in motor responsiveness, deck accuracy, and cushioning.

The X24 is large, heavy, and requires a lot of room, so keep this in mind. If you have the space and budget for it, however, this could be the treadmill of your dreams. I know it’s the treadmill of my dreams.
