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 9 treadmill is a solid choice for anyone wanting a reliable machine for walking, jogging, or running at home. It has a strong 3.6 horsepower motor that supports speeds up to 12 mph, which is fast enough for intense runs or interval training. The running surface is spacious and the SelectFlex cushioning lets you adjust the feel between soft and firm, helping reduce joint impact whether you’re walking or running. The treadmill offers a 0-12% incline range, allowing you to simulate uphill workouts and target different muscles effectively, although it doesn't include a decline feature which some advanced users might miss.

One standout feature is the tilting 10-inch touchscreen, which makes it easy to follow workouts or adjust settings without squinting or straining your neck. The treadmill includes auto incline to switch settings smoothly during workouts. Weighing 210 pounds and made with alloy steel, it feels sturdy and stable during use, supporting up to 325 pounds safely. For those short on space, the treadmill folds up and has a convenient hydraulic system to lower it gently back down.

With 4.3 stars from over 31,000 users, it’s clear many like its performance and features. Assembly is required and may take some time, so be prepared for that. Also, while the cushioning is adjustable, it might not fully replace the feel of more expensive models with advanced shock absorption. The lack of decline inclination and a larger running deck could be a downside for very tall or serious runners. This treadmill offers a well-rounded set of features that suits most home fitness needs, with good speed, incline, adjustable cushioning, and a space-saving design.

The NordicTrack T Series 5 Starter treadmill is a solid choice for adults looking to walk or run at home without taking up too much space. It offers a 2.6 horsepower motor that supports speeds up to 10 mph, which covers most beginner to intermediate workout needs. The running surface is 18 inches wide and 55 inches long, providing enough room for comfortable strides, though taller or very active runners might find it slightly small.

One useful feature is the incline capability up to 10%, which helps add challenge and better simulates outdoor terrain; however, decline options are not available. The treadmill’s cushioning system likely offers standard shock absorption, suitable for general use but not specialized for heavy-impact training. With a weight capacity of 300 pounds, it can accommodate most users safely. The compact foldable design with EasyLift makes it convenient to store and move, ideal for those with limited space.

The 5-inch LCD display is basic but clear, and one-touch controls make adjusting speed or incline during workouts easy. A big plus is the iFIT compatibility, offering thousands of interactive workouts and automatic adjustments, though an iFIT membership is required to access these features fully. This treadmill serves well for everyday fitness enthusiasts wanting a space-saving machine with smart workout options, while it may not meet the needs of advanced athletes seeking high-end cushioning or wider running decks.
