Bought the EA Sports Active 2, with sensors...program is sensible weight training with cardio intervals. New workout routine each day - never boring. And bonus...you can design you own favourite routines. Program even includes 'rest days' to ensure adequate time to regenerate. Tracks & records heart rate which you can see throughout the workout.
Options include programs for beginners through to some really challenging routines. Workouts are enhanced with use of Wii Balance Board, but board not necessary to use the program. Overall, a really good program.
