10 Best Running Machines 2025 in the United States

The NordicTrack T Series 6.5S Treadmill is a versatile running machine ideal for adults who enjoy running and various fitness routines. Its 2.8 horsepower motor provides reliable performance for a smooth workout. The 20” x 55” running surface is spacious enough for most users, while the cushioning system helps reduce the impact on your joints.

The treadmill supports speeds up to 10 miles per hour and an incline range of up to 10%, catering to different fitness levels and workout intensities. The 5” LCD display shows essential workout stats, and the foldable design ensures easy storage when not in use. With a maximum weight capacity of 300 pounds, it accommodates a wide range of users. However, some key features, such as personalized coaching, heart-rate-based training, and automatic adjustment, require a separate iFIT membership, which can be an additional ongoing cost.

The built-in speaker, Bluetooth connectivity, and compatibility with third-party apps like Strava and Garmin are nice additions, but again, some functionalities may be limited without the iFIT subscription. The treadmill's assembly might require some effort, so be prepared for that. The NordicTrack T Series 6.5S is a robust and feature-rich treadmill, but consider the extra cost of the iFIT subscription when making your decision.

The NordicTrack T Series 5 treadmill is a solid choice for adults interested in walking or running workouts at home, especially if you value a compact design that’s easy to fold and store. It has a motor with 2.6 horsepower, which provides enough power for speeds up to 10 mph, suitable for walking and moderate running. The running surface is 18 inches wide and 55 inches long, which is decent for most users, though taller runners might find it a bit limited in length. NordicTrack treadmills generally offer adequate shock absorption to reduce joint impact.

The treadmill features up to a 10% incline, allowing you to simulate uphill terrain and burn more calories; however, there is no decline option, which some runners like for variety. The console has a clear 5-inch LCD display and includes basic one-touch controls for speed and incline, making it easy to adjust your workout on the go. It pairs nicely with iFIT, an interactive training platform that offers thousands of workouts and can auto-adjust speed and incline, but this requires a paid membership.

The treadmill supports a maximum user weight of 300 pounds, covering most adults comfortably. Weighing 130 pounds, it's relatively easy to move around on its built-in wheels. The running deck is somewhat narrow compared to higher-end models, and the screen is small if you want more detailed stats or entertainment. The warranty is strong for the frame but only one year for motor and parts. For those seeking a compact, user-friendly treadmill with interactive training features and decent incline options, this model is well suited, especially when space is limited and running needs are moderate.

The NordicTrack Commercial Series treadmill is designed for those who want a premium running machine with advanced features. One of its major strengths is the powerful 3 horsepower motor that allows speeds up to 12 miles per hour, catering to both walkers and runners. The treadmill also offers a wide range of incline and decline settings (-3% to 12%), which are useful for varying workout intensity and simulating different terrains.

The large running surface (60 inches long and 20 inches wide) provides ample space for comfortable strides. Additionally, the Runner’s Flex Cushioning system helps reduce impact on joints, making workouts more comfortable and reducing injury risk. The iFIT-enabled console with a 10-inch touchscreen offers interactive and personalized workouts, although it requires a subscription for full functionality.

The SpaceSaver design and EasyLift assist make it easier to fold and store the treadmill, which is a plus for those with limited space. The AutoBreeze fans are a thoughtful feature, keeping users cool during intense workouts. However, the machine is quite heavy (275 pounds), which might make initial setup and movement challenging. The subscription requirement for many of the advanced features may be a drawback for some users who prefer not to commit to additional costs. The treadmill supports up to 300 pounds, making it suitable for most adults. The NordicTrack Commercial Series is a good option for those seeking a high-end treadmill with versatile features.
