10 Best Incline Treadmills 2025 in the United States

The NordicTrack T Series 10 is a solid option for anyone looking for an incline treadmill that balances performance and convenience. It offers a 0-12% incline range, which is good for simulating hills and adding variety to workouts, helping you target different muscles for walking, jogging, or running. The motor produces 3 to 3.6 horsepower, enough to support speeds up to 12 mph, so it can handle most training paces comfortably, from walking to running. The running surface measures 20 inches wide and 60 inches long, which provides enough space for most users to move naturally without feeling cramped. This treadmill also folds easily to save space, which is a real plus if you have limited room.

The tilting 10-inch touchscreen adds a modern touch, letting you control speed and incline quickly, and it connects to iFIT for interactive workouts and syncing with other fitness apps. However, keep in mind that the full iFIT experience requires a membership, which is an additional cost. The treadmill can support users up to 325 pounds, which fits a broad range of adults. While the cushioning offers some joint protection, those with sensitive knees or joints might find it less soft compared to higher-end models. Assembly is required and might take some time, which is typical for treadmills but worth noting.

This treadmill serves as a practical choice for adults wanting a variety of incline options, solid speed, and foldability in a compact design, especially if interactive workout programs are valued and investing in the iFIT membership is an option.

The NordicTrack T Series 6.5S Treadmill offers a 0-10% incline range, which is helpful for varying workout intensity and targeting different muscle groups. Its 2.8 horsepower motor is adequately powerful for most home users, supporting speeds up to 10 MPH, suitable for walking, jogging, and running. The running surface is 20” x 55”, providing enough space for a comfortable workout, although it may feel slightly cramped for taller users or those with a longer stride. The treadmill features SelectFlex cushioning, allowing users to adjust the softness or firmness to match their preference, which can help reduce impact on joints during workouts. It includes a range of programs and features through the 30-day iFIT membership, offering access to over 10,000 workouts and personalized coaching using SmartAdjust technology. The ActivePulse feature adds the convenience of heart-rate-based adjustments for a more tailored experience.

With a weight capacity of up to 300 pounds, it is suitable for a wide range of users. The treadmill's foldable design and compact size make it easy to store, saving space in your home. However, the 5” LCD display is relatively small, which might be a drawback for those who prefer larger screens for better visibility. Additionally, while the treadmill has built-in speakers and Bluetooth connectivity, some users may find the sound quality to be average.

The NordicTrack T Series 6.5S is a versatile and user-friendly treadmill with robust features that cater to various fitness levels, making it a solid choice for home use. Potential buyers should consider the screen size and space requirements based on their personal preferences and needs.

The NordicTrack Commercial 1250 incline treadmill stands out in the incline-treadmill category, making it a solid choice for adults interested in running, walking, or jogging. One of its notable strengths is the extensive incline range, allowing users to adjust from -3% decline to a steep 12% incline, which can enhance workout intensity and variety. The 3-horsepower motor ensures smooth operation, supporting speeds up to 12 mph, accommodating different fitness levels and preferences.

The 10-inch tilt and pivot touchscreen is another plus, as it offers customizable views for on and off-equipment workouts, such as yoga and strength training. With iFIT integration, users can benefit from automated workout adjustments based on personal performance and heart rate, promoting a more tailored fitness experience. Cushioning is also a highlight, featuring Runner’s Flex technology to provide comfort during longer runs and reduce joint impact. Additionally, the SpaceSaver design with transport wheels facilitates easier storage, making this treadmill a practical option for those with limited space.

There are some drawbacks to consider. At 275 pounds, it may be challenging to move, even with the EasyLift Assist feature. The requirement of an iFIT membership for full features could be a downside for users seeking a more straightforward, cost-effective machine. While the treadmill is well-built, its assembly can be complex, which might not be ideal for all users. The machine's size may not be suitable for everyone, and it requires a dedicated space. The NordicTrack Commercial 1250 is a robust treadmill for serious fitness enthusiasts, but potential buyers should weigh its size, assembly requirements, and ongoing costs for iFIT against their specific needs.
