Older model LifeFitness X9i crosstrainer in immaculate condition. One owner; residential use. The X9i elliptical trainers were the same as the LifeFitness Commercial Integrity crosstrainers that you would see in the health clubs. The Integrity Series of commercial machines by LifeFitness was arguably the finest commercial grade exercise equipment ever made. The only reason this one is priced this low is because of it’s age. If it was a later model it would easily sell for $1500-$1800.
