10 Best Decline Treadmills 2026 in the United States

The NordicTrack T Series 10 is designed as a solid home treadmill for adults focused on running and general fitness. It offers a decent 0–12% incline range but does not provide decline settings, which may be a downside if you specifically want decline workouts. Powered by a 3.6 horsepower motor, it can reach speeds up to 12 MPH, suitable for walking, jogging, or running sessions. Its 20" wide by 60" long running surface is fairly standard, providing enough room for most users.

A standout feature is the SelectFlex cushioning system, which lets you adjust the deck’s firmness to protect your joints or simulate road running, adding comfort and versatility. The treadmill weighs 245 pounds and supports users up to 325 pounds, offering good stability. The 10" tilting touchscreen makes interacting with workouts and other apps easy, although many smart features require a paid iFIT Pro Membership. This subscription unlocks thousands of workouts, automatic speed and incline adjustments, and health data syncing, which can greatly enhance motivation and progress tracking but adds to the cost.

The treadmill is also foldable, which helps save space in smaller rooms, and it comes with Bluetooth compatibility for heart rate monitors, though those accessories are sold separately. The console is user-friendly, but some may find the reliance on iFIT’s ecosystem limiting if they prefer offline or free workout options. The NordicTrack T Series 10 serves as a compact and comfortable treadmill ideal for those who want guided running and incline workouts at home, with smart features that shine if you're willing to pay for the iFIT membership. However, it lacks decline functionality and may not suit users seeking a more budget-friendly or simple treadmill experience.

One of its standout features is the SelectFlex cushioning system, which allows users to customize the level of cushioning for a more comfortable workout. This is particularly beneficial for those with joint concerns, as it helps absorb impact during exercise. The treadmill is also foldable, making it a great choice for those with limited space, as it can be easily stored when not in use.

The included 30-day iFIT membership offers access to a vast library of over 10,000 workouts led by expert trainers, which can help keep users motivated and engaged.

The large 22 x 60-inch running surface provides ample space, and the 3-zone Variable Response Cushioning system enhances comfort by supporting each phase of your stride, reducing impact on your joints during workouts.
