NordicTrack X22i Treadmill Review

An in-depth review of the Nordic Track X22i Treadmill, a treadmill with a max incline of 40% and a max decline of 6%.

By on February 7, 2019 | Comments

I know what you’re thinking… what on earth is iRunFar doing? It isn’t lost on us that reviewing an indoor exercise machine is the farthest thing from exploring the natural beauty that this website’s community lives for. But most of us also know that a treadmill can give us an opportunity to maintain and build fitness when outdoor running isn’t recommended or possible due to weather, life logistics, and more.

When I was first approached to test the NordicTrack X22i Treadmill ($2,999), I snickered at the idea that I could possibly build mountain-running fitness on a treadmill. My past experiences on treadmills ran the gamut from using incredibly expensive Woodway treadmills in college to being forced inside due to frigid temperatures when I lived in the midwestern United States. It never gelled, and the most I could ever bang out was around eight miles. I felt awkward on the treadmill, and any attempt at fast running made me worry that I’d face plant.

The NordicTrack X22i Treadmill is not your normal treadmill, though, and it’s become a useful tool for both regular run training and training for mountain running–especially for mountain-running training. What follows is my experience with the X22i Treadmill over the course of the last year as I trained for both mountain ultramarathons and a road marathon. I’ll discuss what I’ve enjoyed about this treadmill in particular as a training tool, and I also have some criticisms for some of its shortcomings. Additionally, I reached out to professional ultrarunner Kyle Pietari to discuss his experiences with the treadmill over the past few years and how he incorporates this tool into his busy life and training.

Nordic Track X22i Treadmill Physical Components

I can honestly say that running on the NordicTrack X22i Treadmill is the first time I’ve enjoyed training on a treadmill. Its wide and long belt (22 inches x 60 inches) feels secure, even while doing things like strides at 5:00/mile pace, and NordicTrack’s Reflex Cushioning technology means that I end workouts feeling less beat up than I would if I had done the workout on the roads. The treadmill itself is large and feels solid all around. It shakes very little, even when I’m running at a high incline, and I haven’t experienced any durability issues in a year of consistent use.

Did I mention that it goes up to a 40% incline? Let’s talk about this incline a bit, because it’s no joke and it’s what makes this treadmill a real tool for mountain runners. In fact, at 40% I can barely stay on the treadmill at a hiking pace without using the sidebars for balance. However, the fact that you can train at such ridiculous inclines is really valuable and translates well to hiking up the steeps in races. The treadmill’s decline goes to a much more normal -6%.

Another feature that sets this treadmill apart from others is the ability to select specific speeds and inclines with the push of a button. On the right side of the console are 12 buttons for speed, one to 12, and if I want to run 8:00/mile pace I just hit the ‘7’ button followed by the ‘5’ button for 7.5 miles per hour. This works great on the fly and the treadmill’s speed ratchets up and down more quickly than other treadmills I’ve tried, making intervals a bit more real feeling. On the left side of the console are 12 more buttons to select your incline and decline, everything from -6% up to the dreaded 40%. Although there are also the typical up-and-down arrow buttons to change the speed and incline, being able to press a button once to go up to 10% is really quick and convenient. The touch screen allows one to toggle through various settings in manual mode to see pretty customized data including total ascent, distance, time, pace, heart rate, and more.

I was thankful for the dual fans at the bottom of the console that I’ve used for every single run. They actually work and I haven’t managed to short any of the electronics out with excessive sweating.

NordicTrack makes four models of basically the same treadmill, but with different-size touchscreens. The X22i, the model I tested, has a 22-inch screen. The smallest screen, on the X11i, is 10 inches, and the largest screen on the X32i is, perhaps you guessed it, 32 inches. You probably can also guess that the models get much more expensive as the screens get larger.

Nordic Track X22i Treadmill iFit Software

Okay, let’s start with the screen upon which you interact with the treadmill’s software. The 22-inch screen on the model I tested was absolutely beautiful with a clear picture and snazzy graphics. The first thing you do when you’re programming the treadmill is to connect it to wifi, but, for whatever reason, NordicTrack did not include a web browser! So, don’t plan on streaming or even accessing YouTube. At first this seemed incredulous, so I called NordicTrack last year and customer service told me that this update had not come out yet. If NordicTrack did include a web browser this would be a huge upgrade, as the high-quality touchscreen and speakers do provide a nice viewing experience.

NordicTrack’s proprietary software is called iFit and is touted as an ‘all-in-one’ coaching service. For a $15/month subscription, you can access studio classes, virtual coaching, and destination workouts. I explored some of the free guided runs, including a three-mile jaunt through some of Silverton, Colorado’s trails, and as I ran the treadmill changed grade quite quickly on the rolling trail. It is fun to be able to look at actual scenery of the beautiful trail, however, the whole experience seems a bit wonky as the scenery does not stream past, but rather provides screenshot-style Google images. While NordicTrack clearly believes that users are in the market for ‘professional trainers’ and ‘personalized’ run training, I never found the urge to pay for the iFit service to be able to access the 16,000 on-demand workouts. Instead, I used the treadmill in manual mode and did my normal training.

iFit also has an app that pairs with the treadmill to see your training data. I found this app fairly useless as it doesn’t communicate with any popular training logs such as Strava. If I wanted to upload a workout from iFit to Strava, it involved downloading and converting a file and then uploading it to Strava.

The treadmill also comes with an iFit heart-rate monitor that works very well as far as immediately picking up my heart rate when putting it on and it seems very accurate in tracking quick increases and decreases in my heart rate during intervals. Unfortunately, I’ve had major issues with the iFit heart-rate strap which, for whatever reason, seems to cut into my skin a bit and has left some welts. I’ve tried putting various lubes on the chest strap, but this keeps happening. It could be completely particular to my body, but I don’t have this issue with my Suunto chest strap and I think the fabric of the iFit strap is more abrasive.

Nordic Track X22i Treadmill Overall Impressions

I started training on the NordicTrack X22i Treadmill last February while training for a 100k race with about 16,000 feet of climbing. Starting with little mountain fitness, I practiced getting my legs under me by jacking the incline up above 20% and trying to maintain a little over three miles per hour. I was amazed at how my pulse shot up to 160 beats per minute and I was able to build mountain legs, all while my kids played on the floor next to me.

Since then, the NordicTrack X22i Treadmill has really helped me keep my training consistent. After a long day at work and facing a run in the cold and darkness where I live in Colorado, the ability to just throw on shorts and shoes and feel like I’m doing some parenting means that I’m much less likely to bail on the run. This has been the case this winter as I’ve been training for a marathon. With slick conditions and frigid temperatures in the mornings, I’ve moved most of my speed workouts to the treadmill. Despite Jack Daniels’s treadmill-conversion formula, I find that fast paces on the treadmill are actually quite difficult for me, but those paces transfer with ease once I get outside.

If you’re struggling with balance in your family, work, and running, this treadmill can be a valuable tool that has really acted as a reason to not skip runs when I’m struggling with going out in the dark. While the retail price may seem daunting, NordicTrack offers 0% financing options so you don’t have drop $3,000 all at once.

NordicTrack X11i Treadmill Feedback From Kyle Pietari

If per chance you follow the ultra-consistent ultrarunner Kyle Pietari, then you know that treadmill training is common practice for him. His social media shows several photos of him literally wearing two of his children while hiking on his NordicTrack x11i Treadmill. As a competitive ultrarunner, Kyle has been involved with NordicTrack. Kyle received an X11i Treadmill from NordicTrack in 2017 in exchange for his honest and unbiased feedback. As previously mentioned, the X11i is in the same incline-trainer group of treadmills at the X22i reviewed in this article, but it has a smaller touch screen.

I reached out to Kyle to get his thoughts about training on the X11i and to assess the durability of this hefty investment. “I’ve had my X11i Treadmill for nearly two years. The hardware has always seemed well built, and provides a great feel. I’ve had no issues with the hardware,” he said.

I was surprised by Kyle’s take on treadmill training in general, “I’m a big proponent of treadmills for ultra training. I think for trail runners, using steep incline grades on a treadmill is the best way to practice powerhiking. I learned from my treadmill that 30 minutes at a 30% grade is brutal for me, which means I have a lot of room to improve my powerhiking.”

When talking more specifically about his thoughts on uphill training, Kyle says, “I typically do my interval/speed sessions on uphill grades, whether outside or on a treadmill. I think being able to avoid the downhill during many of those workouts is key to optimizing my cardiovascular strength and avoiding injury. In general, I think trail/ultrarunners would ideally run a lot more uphill than downhill in training. Downhill training is important, but a little bit goes a long way. Uphill training, however, can be done very frequently to maximize fitness. The injury risk and cumulative damage to the body is lower with uphill running than flat or downhill running, but the cardio benefits are greater. Using a treadmill to do more uphill and less downhill, especially at high intensities, might improve longevity as a runner. Just think about Kilian Jornet, who hammers steep uphills during ski-mountaineering season, but gets none of the downhill pounding since he glides down the mountains on skis. Then, when he transitions to running season, his cardio fitness is already world-class, but his legs are fresh from a long period with minimal pounding. Most people can apply this skimo-inspired principle using a treadmill.”

The ability to work training into a busy career and family schedule is also a bonus to Kyle, “Aside from being useful for powerhike training and optimizing my uphill-to-downhill ratio, having a treadmill helps me fit my training into my busy schedule. I usually can’t run outside when I’m responsible for all three of my kids, but sometimes I can hop on the treadmill. I also love doing uphill hikes wearing my kids on my back and/or chest (weight-vest training). Finally, running takes less time out of my day if I use my treadmill instead of running outside, since I don’t have to worry about bathroom stops, packing water, or dressing for the weather.”
