If you feel that way, it's probably because you haven't tried enough different activities to find one that you enjoy. Give yourself and your body a chance to discover that you get more fun from moving then from sitting around. Finding a sport is an important start. There two important things to consider when you're choosing an athletic activity. The only way exercise can help you is if you enjoy it enough to do it several times a week.
Sports sometimes come into the scene in cycles or fads.
You may want to get involved in a particular activity just because it's the one that everyone else is doing. Going for a popular sport can be a good way to get involved in athletics, but it can also be frustrating, discouraging and sometimes expensive. If something like that happens to you, look around until you find a sport that you can do and one that you will enjoy. Trends don't last for long, but the effects of a good exercise program do. Also, it may take you a while to discover how good you are at a sport.
