ProForm 505 CST Treadmill Review

How does the Proform 505 CST treadmill fair when it’s put to the test?

In this section, we’ll mark it against certain points and rate it out of 5 for each category.

Price: 4.5/5

Sitting just above $500 it’s very well priced.

While not as cheap as a budget treadmill, the jump in price is matched with a significant jump in quality.

You’ll certainly notice the difference over cheaper models.

Its vast array of features makes this treadmill great value for money.

One thing you may find is that the price of this treadmill seems to fluctuate wildly even going over the $1,000 mark.

We’ve given it 4.5 assuming it sits around the $600 mark.

Reliability & Warranty: 4/5

The motor is generally considered reliable and is more than able to last long-term.

What makes the motor stand out is that it’s Mach commercial grade which has the ability to stay cool even at high intensities.

With this machine, you’ll get a lifetime warranty on the frame and 1 year on parts.

This length is quite standard across most treadmill brands.

Concerning the motor, it’s a 25-year warranty, which is good, however, there are competitor brands that offer lifetime warranties on their motors.

That being said, 25 years is still a lengthy amount of time (it often makes me think since they are offering that many years worth of warranty why not make it a lifetime warranty?).

Stability and Quality: 4.5/5

If assembled correctly you should have no issues with shaking or wobbling even when using the machine at higher speeds.

The ProForm 505 CST Treadmill is certainly built with quality in mind and all the features are laid out beautifully around the LCD window.

Power & Noise: 3.5/5

At 2.5 CHP the motor isn’t the most powerful on the market, there are other treadmills around the same price that are more powerful.

If you are a high-intensity running fanatic you may want to look at a treadmill that is slightly more powerful.

However, the ProForm doesn’t simply want to have the most powerful motor, but rather a compromise between power and reliability.

That being said, a 2.5 CHP motor possesses plenty of power which will be suitable for most users.

The belt can spin fast enough to reach 10 MPH and the deck can be raised via its incline functions to intensify any workout.

Size: 4/5

The belt area at 55 x 20 inches, is large enough to walk, jog and run comfortably.

In addition, the treadmill is foldable for those looking to keep their house clutter-free.

The ProForm 505 CST Treadmill is reasonably heavy.

It is possible for one person to assemble it, however, having two people is always better when handling something so big.

Furthermore, assembly of this machine can take just over one hour, however, it’s possible for it to stretch over the two-hour mark.

This isn’t quite as quick as some other machines.

It’s also highly recommended to keep everything organised during assembly as people have reported that the assembly process can be difficult at times.

With this in mind, it may be worth considering paying for professional assembly.

Features: 4/5

The ProForm 505 CST Treadmill has a lot of features, most of which you’d expect for a treadmill of this price.

It has built-in speakers so that you can listen to your own music while you workout.

Just plug your phone into the dock and you should find no need for your own headphones.

There are heart rate monitors built into the handles so that you can see your heart rate when you are on the machine.

Having a heart rate monitor is always a nice touch as this is one of the best ways to measure improvements in cardio fitness.

The LCD panel is quite large which is handy as you won’t find yourself having to move your head to get a better glimpse of the screen.

Furthermore, the 505 CST comes with 18 workout programs, which is enough programs to keep you motivated and challenged.

Should You Buy The ProForm 505 CST Treadmill?

Overall the ProForm 505 CST Treadmill is a decent buy if you want something above a budget level treadmill but don’t want to go too near the $1,000 mark (assuming the price hasn’t fluctuated to this price).

With this treadmill, you’ll be getting a machine that can handle walking to light running with ease, and has the added benefits of being foldable to save space.

ProForm is renowned for its quality and reliability, and even at this price range the ProForm 505 CST Treadmill follows suit.

It has just as many features as some of the treadmills over $1,000, however, costs only a fraction of the price.

You’ll even find that some of the treadmills over $1,000 don’t even have the incline features of the 505 CST.

In summary, the 505 CST is a feature-packed treadmill, which is built to last with the biggest selling point being its price.

It is one of the best value treadmills out there on the market.
