10 Best Treadmills 2025 in the United States

The Walking Pad Treadmill by Sperax is a versatile fitness solution designed for home and office use. One of its standout features is the 2.5HP motor, which, while not the most powerful in the market, is quite efficient for its primary use as an under-desk treadmill, offering a speed range of 0.2 to 3.8 mph. Its quiet operation, with noise levels below 45 dB, makes it suitable for office environments where minimal disruption is important. The treadmill supports a significant weight capacity of up to 350 pounds, ensuring it can accommodate a broad range of users.

The running surface is compact, measuring 39 inches by 21 inches, which is ideal for walking but may feel restrictive for those seeking a more extensive running experience. The treadmill includes four vibration intensity levels to help in post-workout recovery, adding a unique element to its functionality. However, it lacks incline and decline settings, which might be a drawback for users seeking varied workout intensities. The cushioning is not specifically highlighted, which suggests it might not offer advanced shock absorption as found in larger treadmills.

The LED display and connectivity with the Sperax Fitness app provide essential fitness tracking metrics, although some users might prefer more advanced console features. Its lightweight and foldable design make it exceptionally portable and easy to store, fitting conveniently under desks, beds, or sofas. This treadmill is best suited for those looking for a compact, under-desk workout solution rather than a full-fledged running treadmill.

The NordicTrack T Series 7.5S Treadmill is a solid choice for those looking to enhance their home workout routine, particularly runners and fitness enthusiasts. One of its standout features is the 7” HD Interactive Touchscreen Console, which allows you to stream on-demand iFIT workouts, providing a personalized and engaging exercise experience. Additionally, the included 30-day iFIT membership is a nice bonus, giving users access to a wide variety of workouts and coaching by expert trainers. The treadmill also boasts a SMART-Response Motor that is efficient and reliable, supporting speeds up to 12 MPH, which should suffice for most users.

Additionally, the 20”x55” tread belt offers a good balance of space for running while being mindful of home space constraints. The machine's ability to fold up for storage is another practical feature, making it suitable for users with limited space. The FlexSelect Belt Cushioning is a valuable addition, allowing users to adjust the cushioning to simulate different outdoor running environments, which can help reduce impact on the joints. However, the weight capacity is capped at 300 pounds, which may be limiting for some users. While the treadmill offers a 0-12% incline range, it does not seem to feature a decline setting, which could be a drawback for those looking to simulate downhill running.

Additionally, the machine's weight of 115.21 kilograms may make it difficult to move around, despite its foldability. Another potential downside is the assembly requirement, which could be a challenge for some users. The console features are robust, but the 7” screen might feel small for some users who prefer a larger display. Despite these minor drawbacks, the NordicTrack T Series 7.5S Treadmill offers a comprehensive package that should meet the needs of most home runners, especially those looking for a blend of technology and performance.

The NordicTrack T Series 6.5S Treadmill is designed for home fitness enthusiasts looking for a versatile machine that accommodates running and walking workouts. One of its standout features is the iFIT membership that offers access to a vast library of over 10,000 workouts with expert trainers, which can keep your routine fresh and engaging. The ActivePulse technology automatically adjusts your workout based on your heart rate, making it easier to stay within your target zones for effective training. Additionally, the SelectFlex cushioning system allows users to customize the impact level on their joints, which is great for those who may have sensitivities or prefer a specific feel during workouts.

The treadmill’s speed range of up to 10 MPH and 10% incline capability supports a variety of workout intensities, catering to both beginners and more experienced runners. Plus, its foldability makes it a practical choice for those with limited space, as it can be easily stored away after use. The console features, including a 5” LCD display and Bluetooth connectivity, enhance the user experience, allowing for tracking of stats and syncing with fitness apps like Strava and Google Fit.

However, the treadmill does have some drawbacks. At 203 pounds, it may be cumbersome to move for some users, and while the motor is competent for home use, it may not withstand heavy daily usage as well as higher-end models. The 55-inch running surface may feel a bit short for taller individuals, particularly during sprinting. Lastly, while the treadmill offers a 30-day free iFIT membership, continued access requires a subscription, which adds to the long-term cost.
