Wii Fit comes with a pressure sensitive Balance board that you put in front of your TV. The board detects any directional changes in balance and is used to interact with the game in various activites. Ofcourse the board uses wireless technology to save you from hurting yourself stumbling over cables on the floor.
The big question people have been asking "can this really get you fit?" In fact several studies have claimed that Wii games can help you with fitness and even promote weight loss because they're so physical. John Moores University in Liverpool found that users could lose up to 12kg a year from exercising daily using Wii Sports sessions
Wii Fit is divided into 4 categories of exercises: Aerobic exercise, Muscle Conditioning, Yoga Poses and Balance Games. In total there are around 40 different activities included. Examples of the training are:
Step Aerobic Exercise: In this game you need to step on and off the Balance Board to music being played in the background.
Muscle Conditioning: Controlled motions using arms legs and other body parts.
Yoga exercise: Make classic poses in this exercise to focus on balance and stretching.
Ski jumping: Make a good jump by squating as low as possible, while maintinging balance, and then quickly standing up.
Balance Games: These fun activities include heading soccer balls and hula hooping. Challanges for the players overall body balance.
Nintendo has said it has at least ten games in development that support the board and not just fitness games either. Fighting and Sports games can also take advantage of the unique balance-based interface.
The wii Balance board can be used for daily Wii Fit tests. Wii Fit will evaluate two key measures tracked via progress charts:
Body Mass Index (BMI): Weight based on a ratio of weight to height. Wii Fit Age: Measured by facturing the user's BMI reading, testing the Wii fit user's center of gravity & conducting balance tests.
Some very overweight persons might feel dissapointment that there is a weight limit of 136kg on the Wii balance board, but if they just work themself down to the weight limit and then start working with the balance board, they will surely lose some weight quickly just by having fun playing.
