10 Best Folding Treadmills 2025 in the United States

The NordicTrack T Series 6.5S Treadmill is a solid choice for those looking to enhance their home workouts. One of its key strengths is the extensive iFIT membership, which offers access to over 10,000 workouts and personalized coaching from expert trainers. The SmartAdjust technology adds a level of convenience by automatically adjusting your workout based on your heart rate, ensuring you stay in your optimal training zone.

The treadmill features a robust motor that allows for speeds of up to 10 MPH and a 10% incline, catering to various workout intensities for both walkers and runners. The SelectFlex cushioning system is also a notable benefit, as it lets you adjust the firmness of the treadmill to suit your comfort level, reducing impact on your joints during workouts.

In terms of design, the folding mechanism is user-friendly, making it easy to store the treadmill when not in use, which is a significant advantage for those with limited space. Additionally, the 5-inch LCD display provides essential workout metrics, and the built-in Bluetooth speakers enhance the workout experience. However, the treadmill's weight of 203 pounds might be cumbersome for some users, especially when folding and moving it. The size of the running surface (20” x 55”) may feel a bit limited for taller individuals or those who prefer longer strides.

The NordicTrack T Series 5 Starter Treadmill is designed for adults interested in walking and running, featuring a compact design suitable for home use. One of its main strengths is the iFIT membership, offering access to over 10,000 workouts with personalized coaching and SmartAdjust technology. This is beneficial for users who value guided training and want to maximize their fitness routines. The treadmill's motor power of 2.6 horsepower is adequate for moderate exercise, and its speed range of up to 10 MPH allows for brisk workouts. Moreover, the running surface, measuring 55 inches in length and 18 inches in width, is fairly standard but may feel restrictive for taller users or those with longer strides.

However, the treadmill requires an iFIT subscription for many features, which could be a drawback for users not wanting ongoing costs. The 300-pound weight capacity is reasonable, catering to a wide range of users, while the cushioning provides a comfortable experience, reducing strain on joints. The folding mechanism helps in saving space, making it a good fit for home environments where space is limited. The treadmill's incline setting up to 10% adds variety to workouts, though it's less steep than some higher-end models.

Console features include a 5-inch LCD display and Bluetooth connectivity, which can streamline fitness tracking, especially with its compatibility with popular fitness apps like Strava and Garmin. The treadmill's warranty covers the frame for 10 years, but motor and parts are only covered for a single year, which might be a concern for long-term users. In summary, this treadmill suits those who are motivated by guided workouts and prefer a compact, foldable design, provided they are comfortable with an additional subscription cost.

The MERACH Foldable Treadmill is a solid choice for home users looking for a compact yet feature-rich machine. Its standout feature is the 15% auto-incline, which helps increase calorie burn, making workouts more effective. The running surface is quite generous at 16.5 inches wide and nearly 41 inches long, offering comfortable space for most users. The folding mechanism is user-friendly with a hydraulic lever that lets you fold and unfold the treadmill quickly and easily, saving valuable floor space when not in use.

With a speed range up to 7.5 MPH, it suits walking and moderate jogging but might feel limiting for serious runners. Cushioning is well thought out, thanks to a 5-layer belt and shock-absorbing pillars that reduce joint impact, which is important for injury prevention. The treadmill can support users up to 300 pounds, covering a wide range of body types. On the tech side, it includes heart rate monitoring and an LED console that shows essential workout stats. The MERACH app integration adds motivation through scenic runs and interactive sessions, which is a nice bonus for engagement.

A few downsides include its weight of about 106 pounds, which might challenge portability despite built-in wheels. Also, while quiet operation is a plus, the absence of motor power details means it is unclear how it handles intense workouts. This treadmill is well suited for people wanting a space-saving, comfortable home unit with incline features and smart workout options, especially if intense running speed is not a priority.
