How good is Wii Fit as a trainer?

Last year in December, I bought Wii Fit as something fun to do while keeping, well, fit. As you probably know, the activities in Wii Fit are divided into four categories: Balance Games, Aerobics, Yoga, and Strength Training. Balance games are designed to help you with your overall balance, Aerobics are to make you fitter, Yoga is to help you with your posture, and Strength Training builds your muscles. Also, with the help of a special Wii accessory, you can find out your BMI (Body Mass Index) based on how much you weigh on the accessory, the Balance Board. So, how do I rate this fitness game? 


Wii Fit makes daunting exercises a little less daunting. For example, when I was doing the jog/run activity in the Aerobics category (there is one), even doing the 20-minute one, I did not feel like stopping at all. However, this is where the cons come in. Even when you may feel like going  to the max, you may end up cheating to make things easier for you, as Wii Fit is only a virtual simulation, and not a real running spot. The other negative is that you cannot enter your own list of exercise procedures (something that is included in Wii Fit Plus, the follow-up). 


Other than this, though, all in all Wii Fit is a fun experience that you must try out. It'll help you with your balance (which has a big effect on your weight), your muscle strength, if you're going to try that out vigorously, and sometimes even your weight.
