The active-play phenomenon started by Wii Sports now spreads to your whole body thanks to Wii Fit and the pressure-sensitive Wii Balance Board, which comes bundled with it. Used together players will experience an extensive array of fun, dynamic and surprisingly challenging activities, including aerobics, yoga, muscle stretches and balance oriented games. The focus of these activities is towards providing a "core" workout, a popular exercise method that emphasizes slower, controlled motions, but it's the fun approach to fitness of Wii Fit that will keep players hooked on fitness for years to come.

The Wii Fit Balance Board
The primary tenet of Wii Fit is balance. Your center of balance, the point between your left and right sides when you stand upright, has a lot to do with your health. Those without an even center of balance will be unnaturally compensating for this imbalance, which causes their posture to become misaligned, increasing the possibility of putting unnecessary strain on their bodies. This is where the Wii Balance Board comes in.

Similar in appearance to a step aerobics board, the Wii Balance Board is much, much more. Easily capable of supporting weights up to a maximum of 300 pounds, it is sturdy and precise, able to measure weight and register pressure accurately when placed on a variety of flat surfaces. This advanced level of sensitivity allows for both the wide range of activities found in the Wii Fit software as well as the board's amazing ability recognize individual players by their weight alone.

Getting Started: Create a Profile
Before you jump into doing exercises and activities, you’ll start by creating a profile. This is done easily and intuitively by simply choosing a Mii, entering your height and age information, and doing a few quick tests that will serve as a baseline for your new Wii fitness regimen. These tests are:

BMI Check: BMI, or Body Mass Index, is a measure of body fat based on height and weight that is the standard used by agencies such as the World Health Organization and the National Institute of Health. To check your BMI, you’ll enter your height then stand on the Wii Balance Board and let it read your weight.

Wii Fit Age: After you’ve checked your BMI, you’ll do a basic balance test and find out your current Wii Fit Age. This basic balance test measures how well you can control your left and right balance. Based on the results, you’ll be assigned a Wii Fit Age.

Four Categories of Fun
Once you have created your profile it's time to have some fun. Wii Fit features four main categories of exercises to choose from: Strength Training, Aerobics, Yoga and Balance Games. Wii Fit will guide you through the first three with the help of your own virtual personal trainer, while the balance games offer variety and fun to help keep you engaged and excited about your fitness goals. In addition, as you spend time exercising, you’ll earn Fit Credits that unlock additional exercises and activities within your favorite categories that will allow you to continue to push yourself. See more detail on the four categories below:

Keep Track of Your Progress
Because keeping fit is an ongoing process, Wii Fit also tracks the activities you do the most and puts them into your Favorites category. With this information players can note exercises and activities that they are strong in, as well as others that may need to improve at. Some of the ways players can use this information for are to:

Keep tabs on your daily progress with easy-to-understand graphs and charts. Using your personal profile, you can set goals, view a graph of your BMI results over time, see how many Fit Credits you’ve earned, check your Wii Fit Age and even enter exercise time you’ve done outside of Wii Fit. It’s all about coming back and exercising a little every day, and the personal profile makes tracking your daily progress simple and easy.

Quickly check your Wii Fit Age and BMI without even putting the game in the console by going directly to the Wii Fit Channel.

Allow up to eight family members can create their own profiles in Wii Fit. On the profile-selection screen, everyone in the family can see each other’s recent BMI progress and Fit Credit total. This will allow families to have a friendly competition to exercise and get fit.

It is retailing for $89.99 in the US. I have already pre-ordered mine and I don't even have a Wii! My sister has one and I figure I'll try it out and if I don't like it I'll give it to her, and if I do like it then I'll have to search for my own Wii.
