10 Best Buy Treadmills 2025 in the United States

The NordicTrack T Series 8 Treadmill is designed for adults seeking a versatile workout machine that combines technology with fitness training. One of its standout features is the iFIT program, granting access to over 10,000 workouts, which can significantly enhance the workout experience for users who enjoy guided training. The treadmill's 3.6 horsepower motor supports a solid maximum speed of 12 mph, making it suitable for both walkers and serious runners alike. Additionally, the varying incline range from 0 to 12% allows users to tailor their workouts to target different muscle groups effectively.

Cushioning is another strength, with SelectFlex technology enabling users to adjust between soft and firm surfaces, providing comfort during high-impact activities. The foldable design is practical for users with limited space, making it easy to store when not in use.

There are some considerations to keep in mind. The required iFIT subscription, while beneficial, can be an added cost for users. Additionally, the treadmill weighs over 200 pounds, which may make it difficult for some users to move around, even with its foldable feature. Assembly is also required, which might pose a challenge for those who prefer a ready-to-use machine out of the box. Moreover, the 7-inch LCD display, while functional, may not be as large or advanced as some users would prefer for easy visibility.

The NordicTrack T Series 6.5S Treadmill is designed for individuals looking to bring their running workouts home. One of its standout features is the 30-day iFIT membership, providing access to over 10,000 workouts led by trainers across the globe. This can create a personalized and engaging exercise experience, especially for those who thrive on variety. The treadmill’s speed range of up to 10 MPH and a 10% incline allows users to adjust intensity easily, catering to both novice and more experienced runners.

The cushioning system is notable as it allows you to adjust the impact level, making it gentler on your joints, which is great for long-term use. Additionally, it folds up neatly for storage, a valuable feature for those with limited space at home.

However, there are some drawbacks to consider. The assembly process might be a bit challenging for non-tech savvy users, as it requires some manual work. The treadmill is also quite heavy at 203 pounds, which could be cumbersome when moving it around, even though it is foldable. The 5-inch LCD display, while functional, may feel a bit limited compared to larger screens on some other models. The weight capacity of 300 pounds is decent and should accommodate most users, but individuals seeking more robust options might need to look further. The treadmill's warranty is good, offering a 10-year frame warranty, which provides peace of mind, but the 2-year parts warranty might leave some users wanting more coverage.

The NordicTrack T Series 6.5S Treadmill is a solid choice for home runners, especially those who appreciate guided workouts and adjustable features. It suits those with space restrictions thanks to its foldability, but potential buyers should be prepared for the assembly and weight considerations.

Its speed range of 0.6 to 6.0 MPH supports a variety of workout intensities, though it may not satisfy users seeking high-speed training options.

The running surface measures 39.37 inches long by 15.74 inches wide, which might feel cramped for taller users or those requiring more space for their stride. However, it’s a reasonable size for basic fitness activities. The manual incline adjustment provides four levels of incline, adding some variety to workouts, though it lacks the convenience of automatic incline settings. One of its standout features is the smart connectivity with the ‘FitShow’ app, allowing users to track their progress, compete with friends, and share achievements on social media.
