I be 41 year old and a couch potato . I have be use this for about a month now -lrb- 3-4 time per week -rrb- and be feel better . the only issue that I have have with it be that sometimes even though i be in sync with the trainer , it do not recognize that -lrb- most of the time it work fine -rrb- . it have get I up off of the couch and move around . I like see the progress make , and the exercise be fun to do . they can be a little repetitive , but that be ok . I be enjoy this enough that I will probably buy the 2012 version in a few month . overall , this be well worth the money .
