The NordicTrack T5.5 comes with all the greatness of its brother, the T5.7, but trims off the bulkiness. It still comes with 20 Certified Personal Trainer approved workout Apps, a CarioGrip™ Heart Rate Monitor, 1-Touch™ incline and speed controls, iFit Live™ compatibility, RaceTrack™ display, and a music port for your iPod®.

The cushion, tread belt, and motor are all the same as the T5.7's, and it still comes with the same great SpaceSaver® design to fold up and out of the way.

The only real differences from the T5.7 is the smaller style of the machine, the RaceTrack display, 2% less incline, a 25 year motor warranty (that's plenty anyways), and 1 year warranty on the parts.

If you're not deterred from the shorter warranty package and need a little bit lighter weight treadmill than this could be a great value to you!
