High-quality Cushioning

The deck area is fully cushioned and allows you to walk, jog, and run comfortably. The cushioning protects your joints and prevents stress related injuries.

Incline Training

Very few treadmills in this price range offer you the option of incline training. The 505 CST can incline up to 10%, which is more than enough to have you sweating bullets in no time. With incline training, you can burn off more calories, stimulate different muscle groups, and develop tremendous cardiovascular endurance.

Heart Rate Training

The built-in sensors in the handlebars measure your heart rate while you train. The heart rate monitoring technology allows you to stay in the right heart rate zone that will help you reach your fitness goals faster.

Powerful Motor

The 2.5 CHP commercial grade motor is quite powerful, especially for an entry level treadmill. It is also very silent, which allows you to watch TV or listen to music while working out without any noisy interruptions.


Workout Programs

The machine comes preloaded with 18 workout programs, which are divided into four different categories – speed, incline, intensity, and calorie. This selection of workout apps is quite good for a budget treadmill. Depending on the program you choose, the machine adjusts the speed and incline automatically.


The frame is covered by lifetime warranty and the motor is covered by a 25-year warranty. It goes to show that the manufacturer is extremely confident in the durability of the treadmill.


The 505 CST comes with an unbelievably small price tag, which is amazing considering the fact that it comes with features like incline training, which are usually found only in higher-priced treadmills.


There are always a few drawbacks to contend with, especially when it comes to lower priced models. Although the ProForm 505 CST offers a lot of bang for the buck, there are some things to note.

Shorter Running Area

The 20″x 55″ tread belt is sufficient if you intend to use the treadmill only for walking and light jogging. If you want to run, you might find it slightly uncomfortable, especially if you are tall. If this is the case you can check out the Performance 600c or one of the Sports Series models.

Lack of Entertainment Options

The earlier version of this treadmill was compatible with iFit Live, which this version lacks. It is quite a downgrade as iFit is one of the favorite features of many people due to the amazing variety of workout options it offers. The machine does have an iPod compatible music port, which allows you to listen to your favorite songs during training sessions.

If iFit is a must, check out one of the other ProForm treadmills.


The assembly may take up to two hours and may require an extra pair of hands. While it is not a big deal for most people, it might be a tad difficult for those who are not mechanically inclined.


The ProForm 505 CST is reliable, extremely affordable, and loaded with a variety of features. Despite a couple of minor shortcomings, the machine is still a very good choice for beginners and casual users. You will be hard-pressed to find a better treadmill or one that offers more value for your money in this price range.
