Proform 450 CX Treadmill Review

The Proform 450 CX Treadmill is one of the growing number of treadmills offering gym like functions on a home machine for less than £600.

Proform have a number of models in the low to mid-range price bracket and have earnt a reputation for making quality machines at a low price.

The Proform 450CX has a good selection of functions and scores a big plus with its iFit Fitness Journal software that gives you daily, weekly, monthly and yearly fitness reports for you plus one other.

For many treadmill users achieving fitness goals depends on staying motivated, the iFit software is a well-designed feature that helps you track your progress and plan changes in your training. It won’t be long before this sort of feature becomes the standard for all machines as consumers will demand it.

The running deck is about average size compared to its rivals but the ProSoft PlusTM shock absorption system gives it a comfortable feel.

It has 10 pre-set programmes offering a good selection of training options but no heart rate control, a favourite with many treadmill users as it maximises your time in the ‘fat-burning zone’. Currently the cheapest model on the market to offer this feature is the Horizon Treo T707 at around £395.

We liked the console’s layout making it easy to read. Speed and incline can be changed with Proform’sQuick SpeedTM Technology, a fancy name meaning you just press a button once to alter the settings.

The two year on site parts and labour warranty is about par for a machine if this price.

Review Summary - In Brief

The Proform 450 CX offers quite a few useful features for a very reasonable price. The iFit software is a big plus in its favour and we feel gives it the edge over most of its rivals. Proform make good quality machines and have a reputation for reliability so it's a pretty safe buy in our view. The main competitor in this price range is the Horizon Treo T707 which for £50 more has heart rate control and an in-built polar chip for chest strap monitoring without the need or holding the grips. However, it doesn't have anything comparable to ifit. Take a look at both and we're sure you'll find one that will suit your needs.
