Built for performance

Designed around a solid 2.5 CHP motor you can build up a top speed of 18kph. At this point, we think that you might be breaking a sweat but your machine certainly won’t be!

A 2.5 CHP motor is certainly enough for the average user, but if you are looking for a treadmill with more oomph then look towards the NordicTrack Commercial 2950C Folding Treadmill which has an impressive 4.25 CHP.

To keep wear and tear to a minimum, there are 1.9” rollers, and to fold the machine away with no trouble, it features a convenient Space Saver design.

With a slightly larger than average running deck size of 20''x 55.1''.  On the 505 CST, you will feel secure and comfortable to give 100% effort without worrying about your stride length.

This ability to push your performance may also bring added stress onto your joints so we’re grateful that ProForm have included their unique ProShox Cushioning.

Let's look a the science of air-based cushioning for those of you who don't know what it is. 

What is air-based cushioning?

With every running session, your knees will feel the pressure of twice your body weight so having correct cushioning is very important.

Every ProForm treadmill is equipped with one of two forms of cushioning.

The 505 CST features ProShox Cushioning technology which is an air-based system that keeps your muscles active whilst reducing impact by up to 28%.

You’ll be able to work out for longer and harder. Just watch as your performance improves dramatically with each session.

So, what programmes are included with the 505 CST?

That's a good question, and we think that you’ll be happy with the response.

The 505 CST comes fully equipped with 18 workout programmes built-in to the system. Each has been designed by professionals to be both motivational and performance pushing. The system includes several calorie burn workouts and one manual setting.

For an additional subscription to iFit, you can also gain access to hundreds of workouts and daily challenges.

Remember that you can always adapt the challenge level of the programme by manually changing the incline feature which can go to 10%. If you were hoping for a treadmill with a decline feature then we would recommend looking towards the NordicTrack X22i which has an impressive 40% incline and 6% decline feature.

Keeping track

Your core workout data is shown in real-time in an easy to read manner on the 5” LCD display. You can easily see your distance, intensity, speed, incline, calories, number of vertical meters and heart rate.

We think that the matrix style setting, which lets you track incline, speed, my trail and calorie tabs all at once is a great way to visually see your performance.

Your heart rate stats are captured either via the hand pulse grips built into the handlebar area or the optional Bluetooth Smart chest strap and wireless receiver.

Additional accessories

The 5” backlit LCD display not only shows you your stats but you can also access the web and watch your favourite television programmes.

There are two tablet holders, on is located in the centre of the console and the second is on top of the console. This way, you can choose to have your tablet in your eyeline as you exercise, much more comfortable!

Low price, great features

Overall, we think that the ProForm 505 CST treadmill is a great addition to any home or commercial gym. It offers a number of excellent features without breaking the bank and is also foldable so can be easily stored.
