True. Weight loss is not always positive. In a hypothetical situation where you lose muscle mass, but maintain the same weight, this is a direct reduction in fitness levels as your body fat percentage will increase proportionally and the remaining muscle loses tone.

Under these circumstances, you would experience a reduction in overall strength as well as endurance (lift less, fewer times).

This is why the BMI is not the best index to use to gauge fitness (for athletes) although it is still valid if the individual is not extremely muscular with a low body fat percentage (like an athlete). Muscle weighs more than fat after all.

If you weigh 175 pounds and are 5'6", the BMI scale will say you are definitely overweight. But if your body fat percentage is in the single digits and you can bench press 350 pounds, you are obviously not out of shape as a straight interpretation of your BMI would imply.

Jogging is a good gauge for level of cardio fitness. For example, if you can run a sustained sub seven minute pace over ten miles while maintaining a heart rate of just over 100bpm; you're in fantastic shape. By contrast, if moving at a 10 minute mile pace is enough to get your heart rate above 150bpm; you're out of shape.

i am definately out of shape.

 Nintendo: Guess What???

Chamelean75: what?

Nintendo: You NEED WII FIT!!! 

Some activity is always better than no activity. If Wii Fit can keep a user entertained and interested long enough to see results, the user wins. As for what happens after... That's another issue.

Maintaining fitness isn't like tuning up a car. You're not finished after the tune up so long as you keep putting mileage on it.

That will be the real test for effectiveness. A gauge to see how long the average buyer uses the program. Otherwise, it's no different that the typical exercise equipment that ends up in the closet.

Even if just used as a scale/monitor, when people stop exercising and eating more they tend to stay away from the scale because many would rather live in ignorance, while knowing full well that they are gaining weight.

If they didn't, they'd be weighing themselves regularly to confirm no change in weight.

love ownage :)

Nice review. It's always good to hear different opinions. But I am still getting the game for fun, simple stretching, and the combination. Of course, also for future games with balance board support.
