18 Built-in Workout Programs

It has 18 pre-programmed workouts that were designed by certified fitness professionals. The variation and intensity of the programs are interesting.

I can say for sure that the programs are carefully planned to give a comfortable experience that yields favorable results.



It has a maximum incline of 10%. I like that there are buttons to quickly adjust the incline. I can easily change it without the hassle of having to get off the track. Sustaining momentum is very important, especially while working out with specific fitness objectives.


QuickSpeed Control

There are times when I want a heart-pumping workout and there are also times when I just prefer brisk walking while watching TV. Its quick-select speed control allows me to shift from one mode to another with a single push of a button.

Design And Specifications

The ProForm 505 CST has a 2.5 continuous horsepower motor which makes it run smoothly and quietly. Its 20 in x 55 in tread belt is stable and its sturdy frame can hold up to 300 lbs. Its incline level can be automatically adjusted between 0 to 10% and the speed ranges from 0-10 mph.



Does setting it up need to be done professionally?

No. It is rather easy to assemble, although I recommend two people to do it because of the treadmill’s weight. The only difficulty I encountered was the lack of proper labeling for some screws and bolts.



Is it quiet?

It is not completely silent but the sound it emits is reasonable for an electronic treadmill.


Does it fold?

Yes it does, but not very tightly. I suggest storing it in a place where nobody will get hurt in case it unexpectedly unfolds.


Does it run smoothly?

Yes. I have not encountered any problems with either the motor or the belt.


Does iFit come automatically with purchase?

No. It has to be purchased separately and an annual subscription of $99 must also be paid.


What devices can be connected to the sound system?

An iPod or any player with a standard 3.5 mm jack can be connected to it.


Does it have a fan?

No, it doesn’t.


Alternative Options

If you are looking for a more advanced treadmill, the NordicTrack C990 is a possible option. It costs about $400 more, but it has a web-enabled touchscreen, a higher maximum incline, 32 pre-set workout programs, and a longer tread belt.

On the other hand, a more affordable yet also efficient alternative is the ProForm Performance 300i Treadmill. Except for a less powerful motor, it has about the same features but costs $200 less.
