10 Best Manual Treadmills 2025 in the United States

The Assault Fitness Runner Pro is a standout option in the manual treadmill category, particularly for those focused on high-intensity interval training (HIIT), cardio, and endurance workouts. One of its strongest features is that it's athlete-powered, which means it requires no electricity, allowing you to train virtually anywhere. This appeals to fitness enthusiasts who prefer a workout that demands maximum effort, resulting in higher calorie burn compared to traditional motorized treadmills. The built-in wireless connectivity via Bluetooth or ANT+ enables easy tracking and integration with fitness apps, adding a modern touch to your workout experience.

Portability is another plus, thanks to its built-in wheels, making it easier to move around. The assembly process is straightforward, and the treadmill requires minimal maintenance, which is a relief for users who might not want to deal with complex setups or upkeep.

The AssaultRunner Pro does have some considerations. Weighing 280 pounds, it’s quite heavy, which may be an issue for those with limited space or who need to maneuver it frequently. Additionally, while it boasts a maximum speed of 20 miles per hour, not all users may need that kind of intensity, which could be overwhelming for beginners. The sturdy alloy steel construction is great for stability but also adds to the weight, making it less ideal for users who prioritize ultra-lightweight fitness equipment. This treadmill is perfect for dedicated adults looking for an intense workout tool, though its weight and advanced features may be better suited for more experienced users rather than complete beginners.

The SB Fitness CT550 is a curved manual treadmill designed for home or light commercial use, making it a solid choice for walking, jogging, running, and interval training. Its 20-inch wide running surface provides enough room for comfortable movement, though the deck length is also 20 inches, which might feel a bit short for taller users or longer strides. One standout feature is the adjustable magnetic resistance with 8 levels, allowing you to increase workout intensity without relying on incline adjustments, which this model does not provide.

The treadmill supports a maximum user weight of 350 pounds, which covers most users comfortably, and its alloy steel frame promises good stability and durability. Since it’s self-powered, it’s energy-efficient and requires no electricity, but this also means the treadmill’s speed depends entirely on your effort, with a top speed of 22 mph. The design includes a water bottle holder, and the LCD screen displays useful workout stats like time, speed, distance, calories burned, and heart rate, helping you track progress easily. Assembly is required, so some setup time should be expected.

While it lacks incline adjustment that some manual treadmill users might miss for varied training, its size and build provide more stability than many folding models. However, it is less portable, so moving it around often could be inconvenient. The CT550 is well suited for users seeking a sturdy, self-powered treadmill with customizable resistance and good tracking features, especially for running and HIIT, but those wanting incline options or easier portability might want to consider other options.

The DELAVIN Curved Manual Treadmill offers a range of features designed to enhance your workout experience. Its standout strength is the curved running belt, which improves running comfort by fitting the natural curve of your feet and reducing joint impact. The treadmill also has a generous belt size of 62.9 x 18.9 inches, providing ample space for running. Another notable feature is its eco-friendly design; it requires no electricity and allows you to control speed naturally by shifting your position on the belt, making it ideal for those who want an energy-efficient workout machine at home.

With a weight capacity of up to 440 pounds, it is robust and suitable for a wide range of users. The treadmill's build quality is impressive, with a sturdy alloy steel frame and corrosion-proof hardware, ensuring durability and low maintenance. The addition of a front digital LED display helps track your fitness metrics in real-time, making it easier to monitor your progress.

The treadmill's portability might be an issue due to its substantial size and weight, making it less convenient to move around frequently. Additionally, the lack of incline adjustment might be a drawback for users looking for varied workout intensities. While it excels in stability and build quality, its portability limitations and lack of incline adjustment options may not suit everyone. This treadmill is best for those focused on high-intensity training and seeking a durable, eco-friendly option for their home gym.
