This is so fun!!! It seems like stats matter on this review so I'm 36, 5'2, 120 lbs, extremely active (weights/cardio/tabata/HIIT 6-7 days a week). This is such a refresher to mix in with my standard training. I find I actually work out longer because I'm having so much fun and feel the added competition that comes with defeating monsters and clearing levels. The ability to customize a full work out or play mini games allows concentration on a specific muscle and adds to the intensity of the workout. My husband is not motivated by traditional workout methods and has thoroughly enjoyed this and has taken intitiative to do these workouts by himself. Less nagging from me, more working out for him. I'd call it a win win. Do yourself a favor and get one of these for yourself and MOVE!
