Health Month is a new game (currently in beta) designed to help you find that ever-elusive motivation that you need to improve your health.
I've been playing the Health Month beta this month and it's been a great motivator to get out of my office chair and onto my bike and into some running shoes. I set some pretty high goals for myself and have been doing my best to try and hit them. As crazy as it sounds, I actually forced myself to take a long bike ride the other day when I was still tired from the previous day's exercise simply because I was low on "life points" in the game.
I've lost five pounds in two weeks because I set a goal of exercising 5 times a week instead of the typical 1x or 2x per week I've been doing lately. Due to some of the medications I take, I've been gaining about 3-4lbs a month since last December, so having my first significant weight loss has been satisfying and I'm feeling better than before. The game is just enough to motivate me to try a little harder while still being fun.
The site runs as a month-to-month thing, so be sure to sign up so you can try it out in October.
