treadmill Doctor Note :
The new Lifespan 4000i 's impact will depend upon how well dealers explain the features. Having an infinitely variable update available via a USB is a great idea but it has to be used to get the benefit.
The new i series from Lifespan is one of the most innovative features we've seen come to market. Using a proven platform, they are using a new console that can interact with a USB port on the console and then update it online by transferring the USB to your computer.
