The first thing I noticed about the NordicTrack Commercial 2450, NordicTrack's newest addition to its commercial treadmill series, is the touchscreen. It has a 22-inch HD touchscreen that resembles a desktop computer screen, so it's huge. It also tilts and pivots so you can adjust it for different uses, like if you want to take workout classes on the floor. The treadmill itself is also on the bigger side since it's a commercial treadmill, but it does fold up using its easylift assist feature, so if space is limited you can always prop up the belt. Assembling this treadmill can take about two and a half hours (as one of CNET's warehouse technicians estimated) and will require at least two people. NordicTrack does offer the option to include assembly in the delivery for an extra $299. This treadmill has both decline and incline options, ranging from zero to 15% incline and up to -3% decline. It's a rarity to find a treadmill that declines, so this is a unique feature. The speeds range from zero to 12 miles per hour and there are quick-touch control buttons on the console, which makes it easier to adjust your speed during interval training. To get the most out of the NordicTrack Commercial 2450, you will need an iFit membership that is included as part of a 30-day free trial upon purchase. Afterward, it will run you $39 a month. Besides treadmill workouts, iFit also offers other types of live and on-demand classes, so you can enjoy a variety of workouts on the floor. The treadmill uses Wi-Fi and Bluetooth so you can connect headphones, a smartwatch or a heart rate monitor. I thought it was a missed opportunity that this treadmill doesn't give you the option to connect your music through Spotify or Apple Music. You'll also want to make sure that you have decent Wi-Fi because it can get spotty if the treadmill has a hard time reading it. During the testing process, I enjoyed the smooth, quiet tread belt of the NordicTrack. This would be an ideal treadmill for both short and tall people since the tread belt is long and wide, and it has a 300-pound max user capacity. Although this treadmill has a touchscreen, it also has buttons for users who like having that option. Right beneath the screen, there's a fan and a console that has buttons that control the incline, decline, start, stop and speed buttons. The cup holders on this treadmill are on each side of the treadmill and are disappointingly on the smaller side. The most they can hold is a bottle or towel and your phone. I'm guessing it was designed this way to keep you focused on your workout instead of fiddling with your phone. I like how you have the option to run or walk in manual mode without taking a class, but iFit itself has a diverse group of classes to pick from. One of the interesting features iFit has is that you can create your own trail using Google Maps to exercise anywhere in the world. For example, if you want to run in Central Park, you can select the location to create that immersive experience during your run. The stand-out feature I was most impressed by was NordicTrack's AutoAdjust technology, which allows an iFit virtual instructor to adjust your incline and speed during class. You could be running or walking in the jungle and you'll notice the treadmill adjust to replicate that terrain. This hands-free option lets you focus on the class without having to fuss with any buttons. It's also a good way for runners who need to train for a race to get the outdoor feel indoors.
