[Machiavelli]

Another thing I suggest that's already been mentioned is team sports.

You do NOT have to be good, like a previous poster mentioned. All you need is a certain level of enthusiasm.

From personal experience, I am not the skilled soccer player around but I'm good at running around for the ball (being pretty fast, long legs, etc.) and got into great shape (flat stomach too!) from playing city league womens soccer. Seriously - if you can make it onto any team where you actually like the sport being played, it goes a long way.

You'll be exercising almost the entire time without actually feeling like your exercising.

It helps to be an A-type competitive person, b/c you'll work so hard for fear of losing!

Man, I really need to get back to that soccer...
