ProForm 505 CST Overview

The ProForm 505 CST is a great option for beginner runners who want a decent treadmill at a low price. For only $999, this treadmill is equipped with a number of good features, including a lifetime warranty on the frame, a 25-year warranty on the motor, and a 1-year warranty on parts. Additionally, it offers a convenient and comfortable user experience with ProShox Cushioning to protect your joints as you exercise. However, it is relatively small, with a slightly cramped running area and a max speed of only 10 mph.

Overall, this treadmill will serve you well if you’re looking for a basic treadmill. Don’t expect to be wowed by its entertainment options, compatibility with other electronic devices such as smartphones and fitness trackers, or speed and incline abilities, but if you’re looking for a treadmill that will serve you well for years to come at a low price, this might just be the treadmill for you.


This treadmill does not sacrifice comfort for convenience. It offers the best of both worlds, with a sleek body that can be easily folded up when not in use. As for the running surface, it is a bit small, but it does the trick for less intense workouts and shorter runners. It offers a relatively smooth ride, with decent shocks to protect your ankles, knees, and hips as you run.

  • ProShox Cushioning for added comfort
  • 20” x 55” running surface
  • Quiet, durable motor
  • Foldable with SpaceSaver design

Display and Digital Features

The display is quite small and basic, serving mostly to tell you how fast you are going and what your current heart rate is. However, it can also be used to navigate through any of the 18 different built-in workouts that it will guide you through. It also comes with two 2” Intermix Acoustics speakers that can connect to most smartphones.

  • 2” speakers with smartphone compatibility
  • 18 built-in workout programs
  • Heart rate monitoring

2.5 CHP

The Mach Z motor is a commercial-grade motor that offers a quiet and smooth ride. It is not the strongest motor, as it only has 2.5 horsepower and provides a max speed of 10 mph, but it will last a long time and is covered by ProForm’s 25-year warranty.

  • 2.5 horsepower motor
  • Max speed of 10 mph
  • 25-year warranty
