NordicTrack Commercial 1250 Review (2026): A Heavy-Duty iFIT Treadmill

The Commercial 1250 is a big, heavy treadmill at about 300 lb, with a 22 × 60-inch deck and a 400-lb user limit. Owners describe a solidly built, commercial-feeling machine, and independent testers found no wobble at 10 mph.

Opinions on reliability are divided, with some owners reporting units that stopped working. Register the treadmill and keep your purchase records so any claim is straightforward.

Bottom line: feels like a gym machine, with mixed reliability reports.

The 3.6 HP motor runs from 0 to 12 mph, which covers easy walks through fast intervals. Owners report that it stays quiet even at higher speeds. On the previous generation with a 3.0 HP motor, one hands-on test measured about 75 dB at one foot at top speed, roughly average for the class.

With iFIT Pro, SmartAdjust adapts speed and incline based on your workout history, and ActivePulse keeps you in your target heart-rate zone using a Bluetooth monitor (sold separately).

Bottom line: strong, quiet running performance.

The 22-inch width gives room to drift without stepping on the side rails, which helps during fast intervals or if you have a wide gait. RunFlex cushioning absorbs impact for more comfortable runs, and one hands-on tester called it one of the best-cushioned decks they had used, with room to spare for tall runners.

The 400-lb user limit makes it one of the stronger choices for heavier runners who want a folding treadmill. On the previous generation, testers flagged 1.9-inch rollers as on the small side for heavy running; the current deck was not measured.

Bottom line: wide, cushioned and built for heavier users.

Incline runs from -3% to 12%, so you can train hills and downhill sections at home. Decline is rare on home treadmills and useful for race preparation. Independent testers found the transitions across the range smooth, and owners like iFIT route workouts that change the incline automatically.

The listing describes workouts through iFIT rather than a set of built-in programs, so plan on the membership for structured training. Without it, reviewers note that only manual mode and a few basic workouts remain.

Bottom line: a full incline and decline range for terrain training.

The 10-inch touchscreen tilts for off-treadmill classes like yoga and strength. An iFIT Pro membership is required to access all iFIT content and connected features, including streaming, for your household.

With the membership, workouts sync with Strava, Garmin Connect and Apple Health, and the iFIT AI Coach can build plans and load your next workout by SMS. Some buyers question the overall value once the membership is included. Testers also found the 10-inch screen smaller and harder to read than on the Commercial 1750 and 2450, noted the lack of quick-adjust speed and incline buttons, and some owners find the touchscreen fiddly for simple walking.

Bottom line: capable iFIT console; the membership is part of the deal.

Assembled, it measures about 77.3 × 37 × 59.5 inches. Folded, the depth drops to about 44.2 inches, but the deck stands about 69 inches tall, and a foot bar helps lower it smoothly. On the previous generation, testers found it still bulky and heavy to move once folded, with small, hard-to-reach wheels.

The 10-inch step-up height raises you higher than most treadmills, so check your ceiling clearance. Owners describe it as quiet, though testers note the fan adds some noise, and a mat helps upstairs.

Bottom line: it folds, but it is not a small-space treadmill.

Owners say it goes together without much trouble, but at about 300 lb, the freight delivery is very heavy and setup is a two-person job.

The data we have lists 2 years on the frame, motor, parts and labor. That is short next to the lifetime frame and motor coverage on the Horizon 7.4 AT and Sole F89, so confirm the current terms on the product page. Testers also point out that the motor coverage is shorter than on the higher Commercial models. One owner reports an early unit failure that was replaced under warranty.

Bottom line: easy to assemble; check the warranty before you buy.
