10 Best Affordable Treadmills 2025 in the United States

The NordicTrack T Series 6.5S Treadmill is designed for adults who are looking for an affordable yet feature-rich treadmill for home use. It has a 2.8 horsepower motor, which is suitable for walking, jogging, and light running. With a maximum speed of 10 mph and a 0-10% incline range, it provides sufficient versatility for various fitness levels.

The running surface is 20 inches wide by 55 inches long, which is decent for home workouts but may feel a bit cramped for taller users or those with a longer stride. The treadmill includes cushioning to reduce impact on your joints, making it a good option for regular use. One of its standout features is the inclusion of a 30-day iFIT membership, offering access to over 10,000 workouts and personalized coaching, though continuing the subscription after the trial will incur additional costs.

The 5-inch LCD display is straightforward, showing essential workout stats, and there's a device shelf for those who prefer to use their own devices. The treadmill is also foldable, which is great for saving space when not in use. While it includes modern features like Bluetooth connectivity, built-in speakers, and auto incline, the reliance on the iFIT subscription for full functionality could be a downside for those looking to avoid ongoing costs. Additionally, at 203 pounds, it’s relatively heavy, which might be challenging for some to move around despite its foldable design. This treadmill is best suited for users who are looking for an interactive and versatile workout experience and are comfortable with potentially investing in the iFIT subscription to get the most out of the machine.

The NordicTrack T Series 9 treadmill is a solid choice for anyone looking for an affordable, feature-rich treadmill for home use. Its 3.6 horsepower motor delivers enough power to comfortably support running speeds up to 12 mph, which suits walking, jogging, and moderate running workouts. The running surface is a decent size, providing enough space for most users to exercise comfortably. One standout feature is the SelectFlex cushioning system that lets you adjust the deck's softness to reduce joint impact, which is great if you want a gentler or firmer feel depending on your workout intensity.

This treadmill offers a 0-12% incline range, allowing you to add challenge and variety to your exercise sessions by simulating uphill running, which helps burn more calories and engage different muscles. It also folds up neatly when not in use, making it practical for those with limited space. The console is quite advanced, featuring a tilting 10-inch touchscreen that streams iFIT workouts and other entertainment. However, to unlock most of these smart features like automatic speed and incline adjustments, as well as syncing with fitness apps and personalized coaching, an additional iFIT Pro Membership is required, which adds a monthly cost.

At about 210 pounds, the treadmill feels sturdy but may be a bit heavy to move frequently, though the folding design and wheels help with storage. The maximum user weight is 325 pounds, accommodating a wide range of users reliably. The warranty is competitive, covering 10 years on the frame, 2 years for parts, and 1 year on labor and tablet, which shows confidence in build quality. This makes the NordicTrack T Series 9 well-suited for home users who want a treadmill with solid power, adjustable cushioning, and smart features. It's ideal for those comfortable with some tech and willing to invest in a subscription to get the most from the advanced interactive workouts, while users preferring simpler use without ongoing fees might find some features limiting.

The Sunny Health & Fitness Foldable Treadmill offers a strong set of features for an affordable treadmill, making it a good choice for adults looking to walk, jog, or run at home. Its 2.5 HP brushless motor is powerful enough to reach speeds up to 10 mph while keeping noise low, which is great for quiet workouts. The running belt is a roomy 20 inches wide and 53 inches long, offering ample space for comfortable movement and better balance, especially for larger users. With 15 automatic incline levels, this treadmill allows you to easily increase workout intensity and mimic outdoor hills, which adds variety to your exercise routine. The cushioning system uses a double-deck shock absorption setup to reduce joint impact, helping protect knees and ankles during longer or more intense sessions.

Foldability is well handled with a one-click fold design, so storing the treadmill when not in use won’t be a hassle despite its relatively heavy weight of 130 pounds. The console features a clear LED display that shows key stats like speed, time, distance, calories, and heart rate. It also includes Bluetooth connectivity to access the SunnyFit app, which offers thousands of workouts and scenic routes to keep workouts engaging. Added conveniences such as cup holders, a device holder, and a USB charging port improve the overall user experience.

The treadmill’s footprint is fairly large, which might be a concern in tight spaces, and while it's fully assembled on arrival, its weight could make moving it challenging. The warranty covers the frame for 3 years but only 180 days for other parts, which is standard but worth noting. This treadmill suits users who want a feature-rich machine with solid performance and a comfortable running surface without spending a lot, especially those who value incline options and smart connectivity.
