Let’s find out why this model is so popular and what it has to offer.

The ProForm 505cst Specs


This machine has a 2.5 CHP motor, which is average. Importantly, it’s a Mach Z commercial grade electromagnetic self-cooling motor, which means that it is powerful, quiet and long-lasting. ProForm backs this up with a 25-year warranty.

The amount of engine power you need will depend on your fitness goals and your weight. This model’s weight capacity is 325 lbs. The 505cst treadmill is excellent for walking and jogging. If you want to run, however, you might want to look for a more powerful machine.

Running Track

Proform 505 cst - A small treadmill with great featuresAt 20” by 55”, the running area is appropriate for walking and jogging. It might be a bit too short if you are very tall and use the treadmill mainly for running. If this is the case, it is better to consider a belt length of at least 58”. A track width of 20” is fairly standard and would suit most trainees.

This machine’s track is propelled by medium size 1.9” balanced non-flex rollers. The size of the rollers, together with the thickness of the belt and lubrication, is important as it decreases tension and ensures smoother running and therefore longevity of the track.

Track cushioning

ProForm has outfitted this treadmill’s entire running deck with ProShox Lite 3 Cushioning, allowing you to have longer, more frequent workouts.


With a maximum track speed of 10 mph, this treadmill is adequate for most trainees. However, a track speed of less than 12 mph is a problem if you want to sprint or use interval training. In that case, you may need to consider a different model.


The 505cst has a motorized incline up to 10%, which is perfect for putting challenges, such as uphill routes, into your training plan. It helps to burn calories efficiently, tones the muscles in the lower body and allows you to achieve your fitness goals faster.

For a more accurate reading, the manufacturer recommends holding on for 15 seconds.

There is no chest strap included in the package. As such, a wireless, hands-free and continuous heart rate reading is not possible.


The console has a compatible music port for your iPod or MP3 player. There are two 2” Intermix Acoustics Speakers, and if you wish you can turn up the volume and follow with your tempo.

Above the LCD screen, there is a place where you can put your iPod or MP3 player and there are two water bottle holders either side of the dashboard area.

Programmable Features

You have access to a variety of onboard programs: five calorie burning, five timed and five distance programs. This amount of functionality is fairly impressive for an entry-level model. Each workout controls the speed and inclines automatically. The programs were designed by a certified personal trainer, with contributions from Jillian Michaels.

There is an iFit Live mode and a manual mode; if you are not connected to iFitLive, the manual mode will be automatically selected.

You can change the speed in increments of 0.1 or 0.5 mph. While you are exercising, the display can show the elapsed time, the distance traveled, workout intensity, calories burned, the number of vertical feet climbed, the belt speed and your heart rate.

You can unlock access to further workout programs if you decide to upgrade your model with an iFit monitor. When you operate the iFitLive mode, the iFit module communicates with your wireless network, allowing you to download Google Maps, or you can create your own route. If you are interested, please follow this link for further information on the iFit technology.


The machine weighs 186 lbs and will take up an area of 73”x68”x36”. As such, it is a good idea to decide where you want to use it before you begin assembly. The manufacturer advises you to place the treadmill on a level surface with eight feet clearance at the back and two feet on either side. In addition, you might want to consider protecting the floor or carpet with a mat.

Assembly requires two people; it is advisable to study the manual before you start putting all the parts together.

All the nuts, bolts and washers, as well as the hex keys, are included in the package; you will need a Philips screwdriver, an adjustable wrench, a needle nose pliers, and  scissors.

The manual describes the assembly in 15 steps including diagrams and the process of putting everything together should not take you longer than an hour.


The manufacturer has coated the running belt with a high-performance lubricant and advises you not to use silicone spray or any other substances on the tread belt or platform.

Folding and Moving the ProForm 505 cst

And although the running deck is not too heavy, the manufacturer advises that, in order for you to be fit to handle the machine, you should be able to lift 45 lbs with ease.

If you want to move the machine once it’s folded, you may need two people.

Where can I buy the Proform 505 cst?

You can buy the treadmill at Amazon, where this machine sells exclusively to Prime members.

You may also buy the treadmill at Walmart, you have the option of free shipping as well as a free store pickup.

When you checkout at Walmart, for a small fee they offer you a three-year care plan and a four-year care plan. The plan covers you for an unexpected breakdown and goes beyond the manufacturer’s warranty.

The technology is housed in a small removable pod, which allows you to switch bands. The Link works with the iFit app and is compatible with the iPhone 4s and above, iPod Touch 5th generation and above, and Android 4.3 and above.


In case you want to return the treadmill to Walmart, you can do so either by returning the item to the store or you can return by mail. There might be exceptions, and it is a good idea to read their policy before you decide on a particular option. Walmart requires that the item be returned in the original packaging, so be sure to keep all the wrapping for 90 days.

The ProForm 505cst is quite a little marvel. As an entry level model, it has an attractive price point,  is solidly build, has a sophisticated motor and it provides enough room for all your walking, jogging and running, plus it is outfitted with plenty of entertainment features to help you attain your fitness goals.

Other positive points of the machine are its EasyLift folding technology, the ProShox Cushioning, an excellent onboard program variety, together with the 2014 model’s iFit compatibility and the audio capabilities.

And indeed, the manufacturer’s warranty shows that ProForm stands behind a well-constructed machine.

On the downside, the 505cst has no chest strap for wireless heart rate monitoring. You might consider a different model if you intend to do more than light running or if you are a taller runner as the track size is on the short side, and the speed only takes you up to 10 mph. Additionally, there is no workout fan.

Overall, however, this treadmill is an excellent choice if you want to train at home and you need a space saving model. It is also a great buy for you if you are purchasing a home treadmill for the first time and you want a quality entry level model.

The machine has been manufactured using top-notch materials to ensure its longevity. It is backed up by an excellent warranty, which you may not find anywhere in this treadmill’s class and price band.
