Is it really one of the best compact treadmills of 2020?

ProForm makes awesome treadmills. From lightweight compact home units to heavy-duty commercial treadmills, they make some of the best machines in the business.

In this article, we’ll review Proform 505 CST treadmill, one of the most compact machines from ProForm.

We’ll outline some of the key features, break down its specs, as well as look at its pros and cons. We’ll touch on some frequently asked questions, and finish up by giving our recommendation on whether or not the 505 CST really lives up to its reputation.


Key Features of Proform 505 CST

Solid Motor

This treadmill is powered by a compact 2.5 CHP Mach Z DC commercial motor that can easily deliver speeds of up to 10 mph.

Even at top speed, the motor runs smoothly and quietly, and it never feels like you’re stressing the machine beyond its limit.

With a 0.5mph to just over 10 mph range, the speed of the treadmill is easily controlled by buttons on the console.

One of the features we really like about the 505 CST is that it comes with 10 Quick Speed Controls, which makes it nice and easy to vary your workouts while you’re running.


LCD Display

ProForm has upgraded the console display on the 505 CST, which is a real improvement from the previous model.

A 5” two-color backlit LCD display is nice and clear and easy to read in almost all indoor lighting conditions. 505 CST LCD Display The display gives you access to multiple different tabs and display modes which give you the power to focus on and analyze your specific workout.

There’s the speed and incline tab, My Trail tab (a virtual 400m track), Calorie Burn tab, and an intensity indicator bar.

The tabs are great features for making it easier to track your progress.


Entertainment Compatibility

The 505 CST treadmill has a bunch of features that make it compatible with many of your entertainment options.

There is a port for your iPod and other mp3 players so you can pump yourself up with your favorite tunes.

The dual 2” speakers housed in the console give great sound and can get really loud if you need some extra motivation.

The tablet holder on top of the console is a nice feature which means you can stream your favorite shows or movies on Netflix or Apple TV and can be connect with ifit coach.


Workout Programs

Another great feature of the this treadmill is that it comes fully stocked with preprogrammed workout routines.

With 19 programs in total, including a manual setting, this has something for everyone. Proform 505 CST Treadmill Workout Programs The workout programs are developed by certified personal trainers and grouped into different categories, including calorie burn, intensity training, speed training, and incline training workouts.

Each category has several programs you can choose from, each with a different intensity or you can use Google Maps running trail across the globe.

Weighing only 192lbs, this ProForm Treadmill is actually pretty light for a treadmill, which makes it easy to maneuver into position or if you have to move it when it’s not being used.

We would definitely advise getting someone to help you set it up during the initial assembly, as the separate components are big and heavy.

Once it is assembled, the 505 CST feels solid and sturdy.

ProForm put a lot of quality into their treadmills’ components, and the 505 CST is no different. So, even though it’s a relatively light machine, it is sturdy enough to feel safe while you run.


Adjustable Incline

The maximum incline of the Proform 505 CST is 10%, and it’s digitally controlled, which is definitely superior to the manual incline adjustment on some of the competitors’ models.

Combined with the 0 – 10 mph speed range, the 0-10% incline offers a great range of running workouts from a gentle walk to high-intensity hill sprints.

You can also use the iFit Smart Cardio App on compatible devices, though this is subscription-based and requires further payments.
