ProForm 505 CST Treadmill review

Reviewing different treadmills here at Lifestyle Updated, the ProForm 505 CST is one of those that you can definitely single out. Packed with features and incredibly sturdy, this beast of a treadmill easily justifies the price tag, and then some.

Equipped with a 2.5 CHP motor, it allows you to run through 18 different workout variations, each designed by a certified trainer. Choosing the mode is super easy with the ergonomic and intuitive interface, which features a fully lid screen packed with different measurements.

The operating board is fully compatible with an iPod, allowing you to play audio files on the high quality audio system. Also integrated, are functions like the heart rate monitor, calorie tracker, distance, speed and several goal setting modes.

This feature rich monitoring capability will keep you occupied for weeks to an end, and you’ll have fun measuring your progress.

Premium-grade quality

Manufactured by ICON Health & Fitness, the quality of the ProForm 505 CST is truly impressive. A very sturdy frame, supplemented by strong handles and quality command board, the feel of it is quite an experience even before you fire up the 2.5 CHP motor.

The model features a super quality incline option, which is rather rare given the price range. It can automatically switch between 0-10 percent giving your workouts an additional boost.

The ProShox cushioning (every brand has a catchy name for their shock absorbing technology), is spot on, since I haven’t felt a single bump. The track runs smoothly regardless of your weight and aggressiveness of the run – small or big strides, it just feels the same.

Super convenient

The command board is easy to use, and the 18 apps give you a wide range of training options. Beginner or advanced, the ProForm 505 CST is excellent for both performance improvement, as well as weight loss.

Aside from the height adjustment option, this model (as majority of the ProForm palate) can fold up, and take a vertical position that is suitable for storage.
