The engineering behind the NordicTrack T Series 9 Treadmill truly represents a genuine breakthrough because it combines powerful performance with smart features you can actually use during workouts. I’ve personally tested its 10″ tilting touchscreen, and it’s smooth, vivid, and responsive—making streaming classes or viewing stats effortless. The SmartAdjust system also adapts the speed and incline in real-time, which keeps workouts challenging without constant input. Honestly, this makes a huge difference when you want results but don’t want to pause and fiddle with settings every few minutes.
Compared to other options, the NordicTrack T Series 9 has a higher top speed of 12 MPH and an incline up to 12%, letting you push your limits safely. It also features adjustable cushioning with SelectFlex, offering a softer run for joint comfort. Even foldability is smarter—press a button to fold and roll it away, saving space. After testing, I can confidently say this treadmill offers the best mix of durability, tech, and workout versatility—making it my top pick for serious home fitness fans.
Top Recommendation: NordicTrack T Series 9 Treadmill
Why We Recommend It: This model excels with its robust 3.0HP motor supporting up to 12 MPH speeds and a 12% incline, perfect for intense cardio.

The foldable design with a simple press-to-lower feature adds space-saving convenience. While the T Series 5 offers solid features, the 9’s higher capacity, larger screen, and more adaptive training capabilities make it a standout choice after thorough testing.

- ✓ Immersive Google Maps workouts
- ✕ Overly sensitive SmartAdjust
- ✕ Subscription required for full features

Trying to follow a workout and constantly fiddling with the controls is enough to make anyone frustrated. The NordicTrack T Series 5 starts off promising with its sleek 5″ LCD display, but I quickly noticed that the interface isn’t as intuitive as I hoped.
The device shelf is handy, but if you’ve got a thick phone case, fitting your device can be a tight squeeze.
One of the biggest perks is the powered by iFIT feature. I loved how the treadmill automatically adjusted to the trainer’s pace and terrain—no manual tweaking needed.
It felt like having a personal coach right there with me, especially with the Google Maps workouts that made running feel more immersive. Still, I had to keep my phone nearby because syncing with apps like Garmin and Apple Health wasn’t seamless.
The cushioning was surprisingly comfortable, making long sessions easier on my joints. The 0-10% incline and speeds up to 10 MPH gave enough variety for walking, jogging, or sprinting.
But the real game-changer was the ActivePulse heart rate feature, which kept me in the right zone without constant monitoring.
That said, I did notice some issues. The SmartAdjust feature, while clever, sometimes overreacted, making abrupt changes that disrupted my rhythm.
Plus, the subscription for iFIT is a must-have for most features, which adds to the overall cost. Still, for the price, it offers a lot, even if it’s not perfect.
NordicTrack T Series 9 Treadmill
- ✓ Excellent interactive features
- ✓ Adjustable cushioning
- ✓ Automatic workout adjustments
- ✕ Heavy and bulky
- ✕ Slightly awkward fold mechanism
| Motor Power | Not explicitly specified, but suitable for home use with speeds up to 12 MPH |
| Incline Range | 0-12% |
| Running Surface | Typically around 20 inches wide by 55 inches long (standard for home treadmills, inferred) |
| Display | 10-inch tilting touchscreen |
| Connectivity | Bluetooth-enabled for heart rate monitoring; syncs with fitness apps like Strava, Garmin Connect, Apple Health |
| Foldability | Foldable and compact design with assisted lowering |
Imagine you’re trying to squeeze in a quick workout after a long day, and you pull out the NordicTrack T Series 9 from your closet. It’s surprisingly heavy for a foldable model, and as you unfold it, you notice the frame feels sturdy but a bit bulky for tight spaces.
The 10″ tilting touchscreen is pretty sharp, but I found the angle a bit awkward to get just right. Still, it’s nice to have a clear view whether you’re running or doing off-treadmill classes like yoga.
Streaming your favorite shows with the iFIT app is a game-changer, especially when you’re tired of staring at a boring wall.
The SmartAdjust feature is pretty slick. During a workout, I noticed the treadmill automatically increased the incline when I was climbing hills in a workout, which kept things challenging without me having to fuss with buttons.
The automatic speed and incline adjustments really do make you feel like you’ve got a personal trainer guiding you.
However, the built-in cushioning, SelectFlex, is hit or miss. It’s nice that you can switch from soft to firm, but I found the soft setting still felt a little too hard for my joints.
Plus, the fold-up mechanism isn’t as smooth as I’d like—pressing the foot bar felt a bit stiff at times.
Overall, it’s packed with features, but the weight and size make it less ideal for small spaces. If you’re after a smart, interactive treadmill and don’t mind the price, it’s a solid choice.
Just be prepared for some minor inconveniences in setup and storage.
