Wii Fit takes the terrible genre of "Fitness Games" and shines hope on them with this surprisingly good game.
Although the purpose of the game is to make exercise more entertaining and convenient, the game also has a very hardcore workout if that is what you desire. Although there is no weightlifting obviously there are lots of activities that will push even the seasoned veteran (Personally I work out nearly everyday of the week from running, upper body, core, or lower body) this allows a wide variety of possibilities. Some of the activities are push up contests, jogging, tight rope walking, boxing practice, various yoga techniques, and also a large variety of games and exercises. They are divided into four categories Yoga, Strength Training, Aerobic, and Balance Games these four each have their own uses and entertainment.
Personally I am not big on yoga, I am not all that flexible but even for me it is an amazing stretching process to do before a serious workout. Balance games I find to be more of a fun category, filled with various mini-games that although designed to improve balance are more of a form of entertainment than exercise. Aerobic is for mainly for calorie burning, probably the most common reason to exercise due to the wish of weight loss. A variety of exercises designed to keep you entertained while you keep your heart rate elevated for a good balanced calorie burn.
Strength training is the main focus of the workout in my mind being the bulk of the muscle challenging exercises. Having a large variety of exercises to single out specific muscles or muscle groups you can work out the muscles you think you need more work on than others. The ability to increase reps will make you able to change from beginner to expert difficulty easily. Although all these exercises and activities are the large portion of the game there are other features, including a calendar for scheduling and recording workouts and such.
Another feature I found very good and still use is the basic daily test, this tells you your posture, weight, and your current BMI. This allows you to keep a day-to-day track of your workout progress and allows you to see what is working for you and what isn't, it may just be my personal opinion but if you do this everyday it will increase your chances to stay with your goal. Speaking of goals, when you play Wii Fit it asks you to set BMI/weight goals in which it will tell you your progress everyday and tell you how close or far you are from this BMI/weight goal. The "Wii Balance Board" is what truly brings this entire game together allowing all these exercises and games to be both performed and monitored. Although expensive the balance board is an amazing piece of technology, not only is it a great scale worth its cost but also a unique pressure sensitive device that will be used for many Wii games to come.
After playing Wii Fit for a while you come to the conclusion that it is a tool to keep you interested and give you the drive to continue. Nearly everything you could do without the balance board but it wouldn't be visual and interactive giving you less motivation to continue and hit your goals. I would rate Wii Fit a 8.6 out of 10 for an amazing attempt to make a game that can provide a sufficient workout while still being fun. Although no workout game I would rate that highly this is the best of its genre in my honest opinion, if you wish to get a fitness game this would defiantly be my first suggestion.
