I ordered this on a Gold Box or some other special a few months ago, but admit I didn't even crack open the package until last week. I finally decided it was time.
I already have WiiFit, which I do like. I also have Outdoor Challenge, which is very fun and very exercise-y. So, why did I decide to try this one, too? Because the package said it personalized an exercise routine for you.
So, after putting the game in, you run through a whole series of information in setting up your program. Along with age, weight and height, you need to measure your bicep, chest, waist, hips and thigh. You input your resting heartrate, and then your exercising heart rate. You also count squats, pushups and scrunches to help the program determine your current fitness level. It took me about 20 minutes to get all the information entered. Then, on to the exercises.
It is a lot like exercising to a video, except there are certain places you have to input information, and you always have the option of stopping for information on how to do an exercise. And it does base the exercises on your current fitness level (it adjusted some things for me after I told it I could not do something -- I'm currently not very flexible), and you do different exercises depending upon the focus you (or the program) pick for the day.
If I can keep this up, I think this will be better for me than the WiiFit, since I don't have to figure out what I need to do. The program will tell me. I hope I can keep it up. I will update in about six weeks!
