The ProForm Carbon TL and NordicTrack T Series 5 are two entry-level iFIT treadmills with nearly identical core specs: a 2.6 HP motor, 0–10 mph, 0–10% incline, an 18 × 55-inch deck, a 300-lb rating, a 5-inch LCD and the same listed warranty. The main difference is folding: the TL folds with hydraulic assisted lowering, while the US T Series 5 is listed as non-folding but is lighter and lower.
The TL ranks #3 and the T Series 5 ranks #4 in our best budget treadmill guide. The TL also ranks #4 in our best treadmill for small spaces guide, and the T Series 5 ranks #5 in our best treadmill for shared spaces guide.

FitScore Duel
Both scores use the weights of our best budget treadmill guide: affordability 35%, performance, durability and comfort 15% each, practicality and features 10% each. Budget buyers want the most treadmill for the money, so affordability counts most, but it still has to run well and hold up. The two tie on performance, comfort, features and affordability; the TL edges ahead on durability and practicality, which explains the 1.2-point gap.
ProForm Carbon TL
NordicTrack T Series 5
Key Differences
- The TL folds with hydraulic assisted lowering; the US T Series 5 is listed as non-folding.
- The T Series 5 is lighter, at about 130 lb against about 166 lb, and about 8 inches lower when assembled.
- The T Series 5 is about 1.6 inches narrower; the depth is almost the same.
- The TL uses ProShox cushioning and the T Series 5 KeyFlex cushioning.
- The T Series 5 listing also mentions Google Maps route workouts with an iFIT Train membership.
- Motor, speed, incline, deck, display, weight limit and warranty are the same.
Motor, Speed and Deck
Both use a 2.6 HP motor with 0–10 mph, 0–10% incline and an 18 × 55-inch running surface. That covers walking, incline walking and light jogging, but the narrow, short deck and 10 mph ceiling limit regular runners and taller users on either model.
Amazon buyers say the TL feels sturdy and stable and runs quietly enough for walking and harder sessions. Across the T Series listing, buyers praise smooth running, although owners of the T Series 5 mention the narrow 18-inch track and a few taller users describe it as slightly wobbly.
Winner: Tie
Cushioning and Comfort
The TL uses ProShox cushioning and the T Series 5 KeyFlex cushioning, and both listings describe them as reducing impact on the joints.
Owners of the T Series 5 say its cushioned deck eases knee strain. We have not found independent tests that measure either system, and both score the same on comfort.
Winner: Tie
Console and iFIT
Both have a 5-inch LCD and a device shelf, and both rely on iFIT for classes, SmartAdjust, ActivePulse heart rate training with a Bluetooth monitor, the AI Coach and syncing with Strava, Garmin and Apple Health. Each needs an iFIT Train membership for these features; the T Series 5 listing also mentions Google Maps route workouts.
Owners of both report that the small display is hard to read without extra light and that there are few useful workouts without the iFIT app. TL owners also mention that stopping the belt resets time and distance.
Winner: Tie
Folding, Footprint and Weight
The TL folds, and a hydraulic system lowers the deck smoothly, so you can clear the floor after each workout. The US T Series 5 is listed as non-folding, and owners confirm it does not fold, unlike some versions sold outside the US.
The T Series 5 is lighter at about 130 lb, about 1.6 inches narrower and about 8 inches lower when set up, which makes it less imposing if it can stay in one spot.
Winner: ProForm Carbon TL
Build, Durability and Warranty
Amazon buyers say the TL goes together in about 90 minutes and feels solid, but several report a breakdown within the first year. Across the T Series listing, buyers praise the build quality, while a minority report units that failed within the first couple of years and reviews are split on assembly and noise.
The listed warranty is identical: 10 years on the frame and 1 year on the motor, parts and labor.
Winner: Tie
Who Should Buy Each
Small rooms and shared spaces: Choose the ProForm Carbon TL if the treadmill has to fold away after each workout.
A permanent walking spot: Choose the NordicTrack T Series 5 for a lighter, lower frame that can stay set up.
Consider Instead
If you want more room to jog without leaving the budget range, look at the Schwinn 815, which ranks #2 in our best budget treadmill guide. It folds and has a 20 × 60-inch deck, a 3 HP motor, 12 mph, 12% motorized incline, works with apps such as JRNY, Peloton and Zwift and lists 10 years of motor coverage.
Final Verdict
For most budget buyers, the ProForm Carbon TL is the better buy: it matches the T Series 5 spec for spec and adds a folding frame, with the same listed warranty. Choose the NordicTrack T Series 5 if the treadmill can stay in one spot and you prefer a lighter, lower machine.
