Frequently Asked Questions

Does this treadmill run quietly?

The Proform 505 CST’s motor allows it to run relatively quietly. If you’d like to ensure that the product is entirely silent, have it on a flat surface and on top of a mat in order to reduce vibrations and other factors that may cause noise.

Is the console easy to see even in areas of high brightness?

There is no guarantee that you will be able to see the console in perfect clarity if you are in an area that is very bright, as the console does not have an adjustable brightness. However, it is backlit, so you will be able to see it in most lighting situations.

Is there an area to place a tablet, magazine, or water bottle, or perhaps a fan?
