The ProForm Carbon TLS is a folding home treadmill designed around iFIT classes on your own device: a 2.6 HP motor, 0–10 mph, 0–12% incline and an 18 × 55-inch deck with ProShox cushioning. A 5-inch LCD and a device shelf replace a built-in touchscreen, and a hydraulic foot bar helps lower the deck.
We score it with the weights of our best treadmill with classes guide, since iFIT classes are the main reason to buy it. This review covers the build, motor, deck, incline, iFIT features and membership, folding and warranty, and which connected treadmill to choose if you want a bigger screen.

ProForm Carbon TLS FitScore
FitScore rates each treadmill on six categories from structured product data, weighted for one buying intent. The Carbon TLS is bought mainly for iFIT classes, so its score uses the weights of our best treadmill with classes guide. Features count most (70%), then performance (10%), with durability, comfort, practicality and affordability at 5% each, because buyers in this group choose a treadmill for the class experience first. For this intent, a membership app with a workout library counts as a feature, since buyers pay for the latest workouts and videos.
FitScore for Guided Classes
How this FitScore was calculated
This FitScore combines 6 category scores using the weights of the buying intent above.
- Features (89): full iFIT auto-adjust support, but on your own device rather than a built-in screen.
- Performance (80): 12% incline and 10 mph cover most class formats except fast running.
- Affordability (90): one of the more budget-friendly ways into iFIT.
- Practicality (71): folds with hydraulic assist and rolls away.
Design and Build Quality
The Carbon TLS uses an alloy steel frame in a folding design that measures 67.5 × 31.6 inches assembled. At about 205 lb, it is a solid machine, not a light one.
The folding frame and hydraulic foot bar are aimed at tighter spaces: fold it after a workout and roll it out of the way.
Bottom line: a sturdy folding frame for rooms that need the floor back.
Motor and Performance
The 2.6 HP motor drives the belt from 0 to 10 mph, and incline goes up to 12%. That fits walking, hiking-style incline sessions and jogging classes, but 10 mph limits faster running workouts.
One-touch speed and incline buttons let you jump straight to a setting without stepping through each increment.
Bottom line: strong incline range, modest top speed.
Running Deck and Cushioning
The 18 × 55-inch deck is fine for walking and jogging. Taller runners or anyone with a long stride may prefer a 60-inch deck.
ProShox cushioning is designed to absorb impact and keep strides comfortable for walking, jogging, running or hiking.
Bottom line: comfortable for walking and jogging classes.
Incline and Programs
With an iFIT Train membership, the treadmill automatically matches the trainer’s pace and terrain, adjusting speed and incline as the class runs. SmartAdjust also adapts workouts to your performance over time.
ActivePulse adjusts speed and incline to keep you in your heart-rate zone, using a compatible Bluetooth heart rate monitor sold separately. These features require the membership.
Bottom line: hands-free incline changes, if you subscribe.
Console, Apps and Subscription
The 5-inch LCD shows your stats, and the device shelf holds the phone or tablet that runs iFIT. iFIT Train gives access to more than 10,000 workouts, plus AI Coach guidance by text message, all with a membership.
That is the main trade-off against the models ranked in our classes guide: rivals like the Peloton Tread and NordicTrack Commercial 2450 build classes into a 24-inch touchscreen. Without a membership, the Carbon TLS works as a basic treadmill.
Bottom line: full iFIT control on a small screen; bring your own tablet.
Footprint, Folding and Noise
The folding frame frees floor space between workouts, and the hydraulic foot bar helps lower the deck smoothly. The assembled footprint is 67.5 × 31.6 inches, compact for a folding treadmill.
Use a mat in apartments or upstairs rooms to reduce vibration.
Bottom line: folds for small spaces, but it is still about 205 lb.
Assembly, Warranty and Support
Plan on two people for delivery and setup given its weight.
ProForm covers the frame for 10 years and the motor, parts and labor for 1 year. That is short motor coverage, so register the warranty when it arrives.
Bottom line: long frame coverage, short motor coverage.

Alternatives to the ProForm Carbon TLS
Best class experience: Choose the Peloton Tread if you want classes on a built-in 24-inch touchscreen, 12.5 mph and 12.5% incline (Peloton membership required).
Immersive iFIT: Choose the NordicTrack Commercial 2450 if you want a 24-inch touchscreen, 14 mph, 3% decline and a 22 × 60-inch deck.
iFIT with a touchscreen: Choose the ProForm Pro 9000 (New) if you want a 16-inch touchscreen, a 20 × 60-inch deck and a 350-lb rating.
Adaptive coaching, steeper incline: Choose the Bowflex T7 if you want JRNY coaching, 15% incline and 15-year frame and motor coverage.
Final Verdict
The ProForm Carbon TLS is a budget-friendly way to get iFIT classes with automatic speed and incline on a folding treadmill. The small LCD means you will run classes on your own tablet, and the motor warranty is short. If the class experience matters most, the Peloton Tread or NordicTrack Commercial 2450 is the stronger choice.
