Hello. My name is***** can help you with your question.
If the elliptical is outfitted with iFit, then the easiest way to do it is to change your iFit profile online. Here is the link to that.
There is also an iFit menu on the screen - just hit the icon in the upper right hand corner and that will get you to the ifit menu where you can change your settings. If this isn't what you are seeing, let me know if we can go from there.
