Wii exercise?

Does the new Nintendo Wii help you exercise while playing video games? To a certain extent, it does. Take for example Wii Tennis. In this game, you basically swing the Wii remote around, trying to imitate real life tennis racket movements. You can move the remote as if you were performing a forehand, a backhand, an overhand, or a serve. If you really get into it, by significantly moving your arms around, you might be able to receive some exercise from Wii Tennis. To do this, you could pretend that you are actually playing real tennis and swing your arms around accordingly. This kind of gameplay is indicative of exercise, because you will be physically moving as if you were really playing tennis. Thus, you will receive at least some exercise. Unfortunately, the Nintendo Wii remote is also a little too sensitive in the sense that you can play Wii Tennis without dramatically moving your arms around. For instance, if you want, you could simply snap your wrist, while keeping your arm motionless, and still be able to play Wii Tennis. The remote will still pick up your small movements. However, this gameplay will definitely not exercise your body, and in the end you'll just be playing any other non-exercising video game. So there are really two directions in which you could go: 1) Play Wii while exercising; 2) Play Wii without exercising. Since the latter does not involve any exercise, we'll forget about it for the rest of this article. So the question really becomes, "If you do exercise while playing the Nintendo Wii, how much exercise do you really get?" Not much. The sole fact remains that the most you can do to exercise is to move around a couple of feet, maybe hop up and down, and swing your arms. Of course, this is much better than any other video game console can boast; but, in relation to physical exercise, the amount of exercise that Wii can give you is next to nothing. Seriously, think about it. All you do is swing your arms around, which definitely does not make your heart beat go anywhere near your target heart rate; so that means you get no aerobic exercise, which means it doesn't improve your cardiovascular system. In addition, there is almost no resistance to your movements--you only swing your arms through the air. So there's not really any strength building going on. Therefore, the Nintendo Wii does not provide much exercise; in fact, it provides almost nothing. This long article arose just because its topic is easy to write about, and not because I'm making a dramatic discovery or trying to prove something amazing. In fact, I think most people already think that the Wii does not provide much exercise. So in conclusion, here's a long article about an idea that people probably already know about: Although it provides some exercise, the Wii provides practically no exercise relative to real physical exercise.
