How long will the Proform 505 CST last?

The Proform 505CST comes across as an entry-level treadmill. With the short warranty Icon offers, it tells us that Icon must not have faith in their motor lasting more than a year. The 1-year parts and labor warranty are a bit disappointing as well. Despite this, if you keep your treadmill well-maintained you might get a few years of light to moderate use.

Brief Overview

The iFit® Coach interactive technology within the ProForm 505 CST brings a level of innovation greatly desired by the tech crowd in today’s world. You’ll be able to take on and challenge your limits as you work out with top fitness experts from around the world, no matter where you are—all without leaving the comfort of home!

Overall Quality

No more excuses that you can’t get in shape or work with the experts no matter where you are. With iFit® Coach, it’s no longer an issue of having no time for yourself; maximizing every workout is now possible no matter how busy life gets. The roomy 20”x55” tread belt gives you plenty of elbow room as your work through your fitness goals. The Proform 505CST has a slightly larger footprint at 61” x 36.5” x 73.5” and is protected by a 10-year frame/1-year parts and labor warranty. Not too shabby at this price range. This treadmill helps keeps you motivated and interested in your workouts with 18 on-board workouts. It also has an integrated tablet holder that allows you to read or watch anything you like while getting fit.

The Proform 505CST at its price range comes across as solid treadmill that has some nice features for walking. If you need an affordable treadmill to begin your fitness journey, then the 505CST is worth considering. The machine comes with a lower-range motor at 2.5 HP which is better than some models that cost more and offers a decent warranty considering how less expensive this model is than others in the Proform family.
