About the ProForm 505 CST Treadmill

The ProForm 505 CST treadmill is designed especially for walkers and joggers. It comes with 18 built-in workouts created by fitness trainer professionals. This ProForm treadmill is a good choice if you are comfortable investing for a bit expensive equipment. With its EasyLift folding mechanism, it has the advantage of easy folding which will save you floor space.

The ProForm 505 CST treadmill model is a little bit more advanced than the Proform ZT3 treadmill, a cheaper treadmill by ProForm. It is sturdy with a maximum weight capacity of 325 lbs. and 1.9-inch balance rollers. The track comes with a cushioning system that reduces the negative impact on your joints, which means it can be safely used by runners who experience back or knee pains.

The ProForm 505 CST Treadmill is available on Amazon, and also in the manufacturer’s shops.

Proform 505 CST Additional Info


Like most treadmills, to ensure the Proform 505 CST treadmill lasts, you must keep it safe from moisture. We recommend you place the treadmill indoors, and avoid working out in your backyard or patio. Also, make sure that your treadmill is perfectly level when you install. Don’t try to compensate for the level difference by placing objects underneath the treadmill. The treadmill itself is adjustable. Occasionally, you may also have to lubricate the running belt and make sure all the screws and bolts are tight.

You can easily find replacement parts for the Proform 505 CST treadmill online. Proform 505 CST treadmill belts are usually the first to wear out. If you are purchasing a second-hand Proform 505 CST, it may be a good idea to change it anyway.

Warranty and Guarantee Information

You will get a lifetime warranty for the frame, 25 years on the motor and only one year on parts and labor. However, with proper care and maintenance, the ProForm 505 CST treadmill can last quite a long time.


The ProForm 505 CST treadmill comes with any workout accessories.  You can purchase a mat to protect your floor. However, since the ProForm treadmill already comes with floor protectors, this mat is not a mandatory purchase. We strongly recommend you buy lubricant for the tread band, however. This will allow you to maintain your treadmill in peak condition for years.

Recommended Routine

The ProForm 505 CST is the perfect home fitness equipment for cardio exercises, and building resistance. As with most of the treadmills, we recommend you start slow. Luckily, the ProForm 505 CST includes programs you can choose from. You can start with the easier workouts first. Instead of increasing the intensity of your workout first, we recommend you gradually increase the length of the workout. You can increase the intensity of your workout routine by adjusting the treadmill incline, as well as the speed of the belt.

Pros and Cons of Using the ProForm 505 CST Treadmill

[su_column size=”1/2″ center=”no” class=””]

Affordability – The main feature that makes the 505 CST treadmill ProForm an optimum choice is the hard-to-beat budget-friendly and entry-level concept of durability and convenience. All in all, it offers quite a lot of features for its price range.
Quick Assembly & Installation – Many of the reviewers who wrote about the 505 CST model, were impressed by how easy it was to assemble and install their new treadmill. Using the standard ProForm treadmill manual and following the instructions included, it shouldn’t take you too long to get your treadmill working and start your workout
18 in-built workouts – The ProForm 505 CST includes 18 inbuilt routines created by specialists and designed to help you reach your fitness goals. You have a lot of options to choose from, as the programs are structured under four different categories, making it easy for you to know what’s best for your specific fitness goals. You can opt for workouts according to Speed, Calories, Intensity, and Incline, which means you are always in control of your progress
Space Saver – Easy to fold and store, this ProForm treadmill will not take up too much space in your apartment. You can keep it in your bedroom or living room. And because it is easy to fold, the ProForm 505 CST will not take up space when not in use
Heart Monitor – This model features heart rate sensors. These are built into the handlebars. This means you can get real-time information about your pulse during workouts. The accuracy of these readings is not 100% perfect. However, they can serve as guidelines for knowing what your heart rate is during your challenging routine
Audio System – You can connect your iPod to the ProForm 505 CST while working out, so this way you can enjoy your favorite tunes and break a sweat at the same time. The audio system is a professional one, and it includes an iPod-compatible port, as well as two Intermix Acoustics speakers to help you keep the pace while jogging.
Adjustable Inclination – A 2.5 CHP motor runs this treadmill. The automated ramp that can be adjusted to a maximum incline of 10% is a very helpful feature. If you are using the maximum inclination when walking or jogging, you will notice an acceleration of your metabolism and an increase in muscle toning


[su_column size=”1/2″ center=”no” class=””]

Track Length – As we have already mentioned, the length of the track is another issue users weren’t happy with. For taller joggers the 55’’ track is too short, and it makes running very uncomfortable and even unsafe. You should be aware of this aspect before making up your mind. This is especially true if you have a longer stride and require a longer track
Warranty Package – ProForm treadmill repair and maintenance issues are a common occurrence with other treadmill models as well, but in the case of the ProForm 505 CST the warranty offered is well below average. With lifetime coverage for the frame, but only one year for the parts which usually break the first, their warranty is far from ideal


Proform 505 CST User Reviews

Customer rating:

The ProForm treadmill parts are generally high-quality. This model does require some time to assemble. Another feature reviewers complained about is the relatively short 55’’ track that proved to be challenging to use for people with a longer stride. But overall, the surface area is large enough to enable running or walking with no concerns.

As we have already mentioned, the customer complaints concerning this product include the ProForm treadmill maintenance issues experienced. While the ProForm 505 CST certainly has its drawbacks, in general, it does do a great job fairly well.

Our Recommendation

ProForm treadmills tend to offer good value for the asking price, and the ProForm 505 CST treadmill is no exception. As with any top-ranking treadmills, there are of course downsides. If you are a beginner looking for a professional treadmill, or if you feel you are not ready to commit to a certain treadmill model, the ProForm 505 CST is a good investment.
