When I decided to invest in a treadmill, the Proform 400 Ri caught my attention. After using it extensively and researching its features, I want to share my experience and guide you through the key points to consider if you’re thinking about buying one.

Design and Build Quality

The first thing I noticed about the Proform 400 Ri was its sleek design. It’s compact enough for home use but still feels sturdy. The frame is solid, and the folding mechanism works smoothly, which is great if you have limited space. If you value a treadmill that doesn’t feel flimsy, this model definitely meets that expectation.

Motor and Performance

The 2.5 CHP motor provides a quiet yet powerful performance. I was able to run at speeds up to 10 mph without any hesitation or noise issues. The incline feature, which goes up to 10%, adds variety to my workouts, making them more challenging and effective.

Comfort and Running Surface

I appreciated the 20″ x 55″ running belt because it gave me enough room to run comfortably without feeling cramped. The cushioning system reduced the impact on my joints, which is something I always look for in a treadmill since I have sensitive knees.

Technology and Features

One of the reasons I chose the Proform 400 Ri was its interactive iFit compatibility. It comes with a one-year iFit membership included, allowing me to access a variety of workout programs and global routes. The LCD display is clear, showing all the essential stats like speed, distance, calories, and heart rate, which helped me track my progress easily.

Ease of Use and Assembly

Setting up the treadmill was straightforward, although it did take me about an hour to assemble it by myself. The controls are intuitive; even if you’re new to treadmills, you’ll find it easy to operate. Folding and unfolding the treadmill for storage is hassle-free and smooth.

Pros and Cons I Experienced
