Initially, it may be difficult for you to understand its functions, but once you find out where everything is, the console is easy to use. If updated technology and a streamlined console are your first choice, then you must go with this treadmill.

The top of the console contains four buttons to the right and four to the left for program selection. Below the main screen is Bluetooth, speed up / down and enter and up / down buttons to tilt to the left. Apart from this, there is a button for a fan and a display to adjust the options.

You can set your device here to watch or listen to any type of media. The depth and position of the media shelf is given favorable.


Two pockets on either side of the console have been added to handle your extra stuff, in that you can keep a small water bottle, phone, keys. It also has a large storage tray that adds additional storage.

Keep it near a wall outlet when not in use so that you can unplug it even when it is not being used. Due to this space-saving feature, this folding treadmill remains the first choice of the people.
