NordicTrack T Series 5 Treadmill Review: Worth It?
The NordicTrack T Series 5 suits home walkers and runners who want iFIT guidance, speeds up to 10 MPH and a 0–10% incline. Its 55 x 18 in deck and 5 in LCD are straightforward, while connected training features require an iFIT Train membership.
Choose it if you value guided workouts and automatic adjustments. If you want a wider running surface or a steeper incline, compare the Sunny or MERACH options below.
What does the NordicTrack T Series 5 offer?
The T Series 5 combines up to 10 MPH, 0–10% incline and KeyFlex cushioning with an LCD display. You can use a phone or tablet to follow iFIT trainers and have the treadmill adjust to workouts.
NordicTrack T Series Treadmills for Home: Best for guided iFIT workouts
- Up to 10 MPH
- 0–10% incline
- 55 x 18 in deck

A home treadmill for walkers and runners who want iFIT guidance and automatic speed and incline adjustments. The 55 x 18 in deck and 10% incline are the main limits to weigh against alternatives.
Pros
- Up to 10 MPH
- 0–10% incline
- KeyFlex cushioning
- iFIT workouts can adjust speed and incline
Cons
- iFIT membership required for connected features
- Bluetooth heart rate monitor sold separately
- Narrower deck than the Sunny alternative
The product title covers a T Series family that includes the T5, T6.5s, T7, T10 and T16. Confirm that the exact model you are considering is the T5.
Who should consider the NordicTrack T Series 5?
This treadmill may suit you if you plan to walk, jog or run at up to 10 MPH and want incline changes during workouts. If you are choosing footwear for treadmill sessions, see the best running shoes for treadmill use.
Its iFIT features may appeal if you follow trainer-led sessions and value speed and incline adjustments that match the session.
It may be a weaker fit if you want more than 10% incline, a wider belt or connected workouts without a membership. Compare the exact model and your room measurements before deciding.
What matters most in the T Series 5 review?
The key trade-off is guided iFIT workouts versus running space and incline range. The T Series 5 offers automatic workout features through iFIT, while alternatives have wider belts or higher maximum inclines.
| Treadmill | Speed | Incline | Running surface or deck | Distinctive feature |
|---|---|---|---|---|
| NordicTrack T Series 5 | Up to 10 MPH | 0–10% | 55 x 18 in | iFIT guided workouts and KeyFlex cushioning |
| Sunny Health & Fitness Fully Assembled Auto | Up to 10 MPH | Up to 15% | 20 x 53 in | Fully assembled setup and 24 workout programs |
| MERACH 15/18% Auto Incline | Up to 8.7 MPH | Up to 18% | 18 x 47 in | Hydraulic folding system |
NordicTrack specifies deck dimensions, Sunny gives a running surface and MERACH gives a running belt. Compare the measurements with your stride and the space you have.
What do you need for the iFIT features?
The T Series 5's connected training features require an iFIT Train membership. Consider whether guided workouts are part of your routine.
With membership, the treadmill can automatically adjust to match a trainer's pace and terrain. SmartAdjust can adapt speed and incline based on workout history and performance, while Google Maps workouts offer map-based routes with terrain simulation and Street View.
ActivePulse uses a Bluetooth-enabled heart-rate monitor, sold separately, to adjust speed and incline around a heart-rate zone. Through iFIT, the treadmill can also sync workout information with Strava, Garmin and Apple.
These features may be useful if you follow guided sessions often. If you mainly walk at a steady pace, compare speed, incline, fit and controls with the features you expect to use.
For more context on connected training, see our guide to the best iFIT treadmills for home.
Is the 55 x 18 in deck large enough?
The T Series 5's 55 x 18 in deck gives you a surface to compare with your stride and available floor space. Consider your usual pace and how much side-to-side room feels comfortable.
Measure the treadmill's full footprint and the route into the room before ordering. Its dimensions are 68.3 in deep, 30.5 in wide and 48.7 in high, and it weighs 130 lb.
Its folded dimensions are also 68.3 x 30.5 x 48.7 in, so folding does not reduce its stated depth.
The Sunny running surface is 20 x 53 in, which is 2 in wider and 2 in shorter than the T Series 5 deck. MERACH's 18 x 47 in belt is narrower and shorter than the NordicTrack deck.
Choose based on the belt dimensions and how you plan to use the treadmill. A compact footprint alone doesn't tell you whether a deck will feel comfortable during a longer stride.
How does the T Series 5 compare with other T Series models?
The T Series 5 is one option in a family with separately named T Series 7, 10 and 16 models. Compare the exact model you are shopping for, since the family name alone doesn't show which features each treadmill includes.
Our NordicTrack T Series 7 review examines another model in the series. You can also read the NordicTrack T Series 10 review and NordicTrack T Series 16 treadmill review to compare other named options.
Our NordicTrack T 6.5 S treadmill review covers that model separately. Compare the features and dimensions for each exact treadmill before deciding which one fits your plans.
Which alternative fits a different priority?
The Sunny and MERACH treadmills suit buyers whose main priority is more incline or a wider running surface. Sunny reaches 15% incline and has a 20 in wide running surface, while MERACH reaches 18% incline and folds hydraulically.
Sunny Health & Fitness Fully Assembled Auto: Best for a wider running surface
- Up to 10 MPH
- Up to 15% auto incline
- 20 x 53 in running surface
- 24 workout programs
A wider running surface and higher incline make this a useful comparison for buyers who want more room or hill settings. It includes 24 preset programs and SunnyFit app access.
Pros
- 20 in wide running surface
- Up to 15% auto incline
- Fully assembled setup
- 24 preset workout programs
Cons
- Shorter running surface than the NordicTrack deck
- LED display rather than LCD
Sunny's treadmill comes fully assembled and has a one-click fold design, 24 workout programs and SunnyFit app access. Its 20 x 53 in running surface is wider than the T Series 5 deck, but 2 in shorter.
MERACH Treadmill with 15/18% Auto Incline: Best for a steeper incline
- Up to 8.7 MPH
- Up to 18% auto incline
- 18 x 47 in belt
- Hydraulic folding
A folding treadmill with an incline reaching 18%, suited to home workouts that focus on walking and hill sessions. Its stated top speed is lower than the NordicTrack and Sunny options.
Pros
- Up to 18% auto incline
- Hydraulic folding system
- LED display and app controls
Cons
- Top speed is 8.7 MPH
- Shorter belt than the NordicTrack deck
MERACH's top speed of 8.7 MPH is below the 10 MPH offered by NordicTrack and Sunny. Its 18% incline may suit you if steep hill walking is central to your routine and that lower maximum speed works for you.

Is the NordicTrack T Series 5 a good choice for seniors?
The T Series 5 may suit a senior who wants a home treadmill with a 10 MPH maximum speed, incline control and guided workouts, if the deck and controls fit their needs. Its stated features alone can't determine whether it's safe or comfortable for a specific person.
Consider stable footing, easy-to-reach controls, room around the machine and the ability to stop quickly. Review the manual, and seek medical guidance before starting exercise if balance, mobility or a health condition is a concern.
For a broader set of considerations, read our guide to the best treadmill for seniors.
How should you decide if the T Series 5 is worth it?
The T Series 5 is worth considering when iFIT guidance, 10 MPH speed and a 10% incline match your routine. Its main trade-offs are the 18 in deck width and membership requirements for connected features.
Pick NordicTrack if you expect to use trainer-led workouts and automatic adjustments. For another brand comparison, see Sunny Health and Fitness treadmills.
Pick Sunny if a wider surface, fully assembled setup or higher incline matters more, and pick MERACH if you want the steepest incline and a hydraulic folding design. For another brand option, compare the best ProForm treadmills for home.
Compare the treadmill dimensions with your room, then decide whether connected training fits your routine. If those priorities don't fit, start with our NordicTrack T Series 7 review or compare the wider choices above.
