10 Best Under Desk Treadmills 2025 in the United States

The Walking Pad Treadmill with APP by Sperax is a versatile fitness solution designed for under-desk use, ideal for home offices. Its compact dimensions (39 x 21 x 3.5 inches) and light weight (27 pounds) make it easy to store and move, fitting conveniently under desks, beds, or sofas. It offers a speed range from 0.2 to 3.8 mph, powered by a 2.5HP motor, which supports a maximum weight of 350 pounds.

The low noise level of under 45 dB ensures a quiet workout, perfect for maintaining focus in a shared space or office environment. The treadmill features an LED display and connectivity with the Sperax Fitness app for real-time fitness tracking, showing metrics like calories burned, speed, time, and distance. Additionally, it includes four vibration intensity levels for post-workout massages, adding a unique element to this treadmill.

The treadmill excels in portability, ease of use, and quiet operation, although its maximum speed of 3.8 mph may be limiting for users seeking higher-intensity workouts. The vibration feature, though interesting, may not appeal to everyone and could be seen as a gimmick. Considering these aspects, this treadmill is best suited for those looking for a convenient, low-impact exercise option that can be easily integrated into a home office setup.

The MERACH W50 is a solid choice if you want an under-desk treadmill that supports heavier users, with a strong 400 lbs weight capacity and a 16.5-inch wide running belt that offers extra stability and comfort. It’s designed with a durable alloy steel frame and a quiet 3.5 HP brushless motor, keeping noise at a low 25 dB, so it won’t disturb your home or office environment. The speed tops out at 4 mph, which suits walking or light jogging, making it great for gentle workouts or staying active while working.

A standout feature is its 12% automatic incline, controlled by a remote, which helps increase calorie burn and reduces knee strain—useful for rehab or more intense exercise sessions. Cushioning is another strong point, with multi-layer shock absorption reducing impact on your joints. The treadmill is compact at just over 50 inches long and 22 inches wide, slim enough to fit under most desks, and it has sturdy wheels to move it around easily. However, it weighs nearly 70 pounds, so it’s not the most lightweight option if you plan to move it frequently.

The maximum speed and incline might be limiting if you're looking for a treadmill for running or very intense workouts. The controls are simple with a handheld remote and LED display, which is user-friendly but lacks advanced features like app connectivity. The MERACH W50 is well-suited for users looking for a quiet, stable, and joint-friendly walking treadmill that fits under a desk, especially if you need higher weight support and incline options. It’s less ideal if you want something lighter or for faster running.

The TRAILVIBER Walking Pad Treadmill stands out with its impressive 12% 9-level auto incline, making it a versatile option for those wanting to enhance their workout by simulating hiking and mountain climbing. Its compact design and dimensions (48"D x 21"W x 4.8"H) make it suitable for small spaces like apartments and offices. The treadmill's weight capacity of 450 lbs is notably high, catering to a wide range of users. Additionally, the 2.5 HP motor ensures smooth and quiet operation, which is great for maintaining a peaceful environment at home or work.

The speed range of 0 to 4.0 mph is suitable for walking and light jogging, though it may not satisfy those seeking high-intensity running workouts. One of its standout features is the RGB LED screen, which provides clear visibility of your metrics like speed, calories burned, time, incline level, and distance. The treadmill also excels in joint protection with its triple cushioned structure design. However, at 44 pounds, it may be somewhat cumbersome to move frequently, despite its portability claims.

Another potential drawback is the maximum speed of 4 mph, which may limit its appeal to serious runners. The product's quiet operation, auto incline, and high weight capacity are major strengths, making it a good choice for individuals focused on low to moderate intensity workouts in constrained spaces. Its commercial-grade build and comprehensive customer service further add to its appeal, making it a reliable option for long-term use.
