Wendy finally found a use for our Xbox--besides making us all feel guilty for wasting time in front of it.
We found an aerobic/yoga/fitness "game" called Yourself Fitness. Basically, it is a glorified areobic tape, but it appears to be a great way to get personalized aerobic workout without the repetitiveness of a VHS/DVD. It does an interview to find out your fitness level, asks about your goals and creates an individual program for you. The instructor appears onscreen and leads you as in a regular tape, but she's completely computer-generated. The graphics are very well done.
