Lifespan TR4000i Treadmill Review
TREADMILL DOCTOR NOTE :
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.
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.
