In this ProForm 905 CST Treadmill review, we are going to come closer to this high-quality workout machine’s performance and features.

905 CST treadmill has a heavy-duty steel frame construction and weighs more than 200 lbs when it is fully assembled.

The importance of treadmill weight can’t be overemphasized as it gives the machine a good stabilization, ensuring you to keep a steady running posture.

Although the weight is much, handling of the ProForm 905 CST treadmill is not tricky. The front base frame of this machine is designed with transport wheels, which is good for its relocation or movement.

Its 3.0 CHP motor offers a running speed of up to 12 mph. And the incline can reach to 12%, which provides you a more effective workout option.

It is large but small when it is compared with other models and covers a floor space of approximately 79″L x 37″W or 201 x 94 when measured in centimeters. But for safety, the ProForm 905 CST needs a workout surface when in operation.

There are certain things you must consider before buying to avoid regrets or waste of resources. It would be better to check the pros and cons of this treadmill.


  • High user weight capacity (up to 360 lbs)
  • Compact, stable and quiet
  • It is both Bluetooth and iFit enabled
  • It has an excellent warranty
  • The display of the machine is nice


  • The speaker is not loud enough
  • The fan is not well-positioned as it blows on the face of the user
  • Only the speed is displayed.
  • The running surface is not wide enough for some people
  • The iFit membership is not included, so you may want to pay a monthly subscription (but not mandatory).

Frame & Surface

Every buyer or user is recommended to keep this in mind. Another feature of the ProForm 905 CST treadmill is a folding frame. You can fold and lock the deck in an upright position through the latch located on the left console mast.

Nevertheless, the machine lacks a hydraulic assist system, unlike the Nautilus T618 that supports deck unfolding. It would help if you lowered the deck yourself when you want to unfold the deck. When the deck of the machine is uprightly locked, the length is reduced to 2/3 approximately.

The deck of the ProForm 905 CST treadmill is very strong and can support close to 360 lbs (~159 kg) users. This treadmill utilizes an industrial-grade rubber belt that offers a running surface of 60″L x 20″W (152.4 x 51 cm).

And also, for the reason that it promotes accurate leg extension and a natural stride, this running space will comfortably accommodate users close to 196 cm or 6’5″. 905 CST is a great treadmill option for tall runners.

The belt of the machine rolls more than two precision-machined 4.8 cm crowned rollers, and the crowning increases the belt’s lifespan, and it’s rollers’ grip. Just like every other ProForm treadmills, it has a deck cushioning system (ProShox™), which is made up of 3 spring cell pairs.

As a result, walking or running on the machine leads to lower joints pains and longer exercise duration.

The steel frame of the ProForm 905 CST treadmill is double-coated with both rust and chip-resistant paint finish; the frame is black while the console masts are painted silver.

And durable material is used in constructing or designing the motor cover and other covers.

Incline & Step-up Height

A motorable incline system is used in designing the ProForm 905 CST treadmill. This shows that controlling the incline system from the machine’s console is possible.

You can also connect the unit to a power source. Automatically adjusting the incline is possible because of the many onboard programs the console has.

The incline system of the treadmill has a small lift that is located below the deck’s front section, and this small lift gradually takes the front section of the deck up when the incline is adjusted from the console controls.

The console offers the users a 1% adjustment increment and 12% incline levels. There are two types of incline controls located on the console, the quick incline adjustment, which covers the 12% (0% – 12%) settings, and gradual incline adjustment.

The running surface is 20 cm above the floor level when you are considering the step-up height of the deck while the height of the front pack will get to 34 cm or 13.5” when the incline is set to its highest position.

Using the ProForm 905 CST treadmill inside a room that has close to 38 cm or 15” ceiling height more than your height is recommended. So, install your machine to this height to make the most out of it.

ProForm 905 is the upgraded version of ProForm 705. There are big similarities between the ProForm 905 CST treadmill and the ProForm 705 CST treadmill, like their dimensions and frame construction.

Although both are similar, the weight capacity is higher, together with additional workout programs. Also, the ProForm 905 has a better powerful motor – the 3.0 CHP motor, which is an industrial grade.

This 3.0 CHP motor supports long-distance running exercises without losing performance or having the machine overheating.

The ProForm 905’s motor is designed with a small flywheel, which assists in improving stability, smoother movement of the belt, and reducing vibration.

This motor provides a speed range from 0.5 MPH – 12 MPH. Just like the incline explained above, the console of the motor features controls for both the quick speed adjustment and gradual speed between 1 to 12 MPH.

The gradual adjustment keys make it possible for the increased 0.1 MHP and 0.5 MHP resistance to be adjusted.

When a button is repeatedly pressed, the belt of the machine speed will be changed in 0.1 MPH increment.

On the other hand, the speed of the belt will adjust or change to 0.5 MHP in increment when the button is pressed and held. This alone is one of the exceptional features of the machine.

It makes it easy for trainers to find their pace comfortably during a workout. The noise given out by the ProForm 905 CST treadmill motor is not extreme.

ProForm 905 CST Treadmill Console

The difference between the ProForm 905 CST console and ProForm 705 CST is not much. The ProForm 905 console has a blue LED backlight in addition to large digits and 5 inch LCD that promotes readability.

Heart rate and time are parts of the exercise metrics displayed. The intensity bar of the 905 CST console shows an intensity level and grid of your exercise in an approximate figure.

The 905 console is telemetric that tracks your pulse rate through an accessory known as the Bluetooth HR chest strap transmitter.

You can sync the console of this machine with your smartphone because of being iFit enabled. You can also use your laptop or tablet to sync it provided an iFit app is installed in them.

The synchronization is done with these gadgets to directly stream the data of your workout or exercise to your iFit account. However, an iFit membership is not part of the component of the ProForm 905 CST treadmill.

In the control unit of the machine, you will see 30 different workout programs that are divided into four categories — speed, calorie, incline, and intensity.

Every workout or exercise is shown as a segmented grid. There are one incline and 1-speed setting programmed for every segment. While working out, you will see your speed and incline progress.

Other Features of ProForm 905 CST Treadmill

When amenities are put into consideration, the unit’s console has the following components: 2 accessory trays, a tablet holder, and a cooling fan.

The sound system of the console has two big speakers situated on each side of the machine unit. The console also comprises an audio jack input. With this, connectivity of the console with your phone, MP3, or tablet is possible.

You can listen to music via the speakers that are integrated. Also, there is the availability of volume controls on the console.

The tablet holder of the console is seen on the console unit top. It is very large that it can contain other tablets.

The two accessory trays it comes with are located on each of the console sides, the top of the console unit. You can store hydration bottles (to quench your taste) and other accessories because of its large size.

The powerful cooling fan of the console that has many intensity settings is situated at the base of the unit.

There are different opinions from different users regarding this cooling fan. Most of them consider it more powerful than the older ones.

Assembly & Maintenance

The majority of the treadmills people buy are pre-assembled. This simply means that parts of the ProForm 905 CST treadmill are assembled.

For example, the drive and incline motors are completely assembled just as the deck and the belt.

The cushioning system is also assembled with other elements of the treadmill. As a result of this, you have a little task to do. All you have to do is to attach the console and the console masts.

Assembling this may take you close to 1 hour as it is not difficult. The user manual that the machine comes with plays a big role in the assembling of the treadmill through the clear step-by-step instructions.

For proper movement, the belt of the machine should be lubricated just like other treadmills. The ProForm 905 CST treadmill is already lubricated before you purchase it, so you don’t need to lubricate it for a long time.

Wiping of the running belt with a damp cloth should be carried out after every exercise or workout. This will go a long way to prevent textile fibers or any other small objects entering the motor or dragged into the rollers.

The Verdict

From the strengths which include a good warranty, limited space needed, and stability derived from working out on the treadmill, the machine is a good buy.

Also, if you are overweight, the machine is good for you. The treadmill also has its weaknesses, as stated above, so it is your personal opinion or choice either to buy the machine or not.
