My Wife and I were done with the club / 24 hr Fitness scene……. Tired of waiting in line for a treadmill or elliptical machine. Went to Dick’s, Sears, and Sam’s to shop but found the sales guys were not much help with info. Online there were many selections and many prices. We found the 6.8 Xterra website and felt we could not go wrong with the warranty and features. One month later I’ve lost 22lbs and my Wife has lost 10. We love our Xterra treadmill.
