I have always had trouble using treadmills. They never keep my attention for more than a half-hour. Then I was introduced to a great game that helps you loose weight and is addictive! Its called Dance Dance Revolution, and it is no different than jogging. The game plays techno/dance music and arrows appear on the screen. When the arrow enters the stationary arrow at the top of the screen, you press the corrosponding arrow on a "dance pad" that you stand on. It is very addictive and well worth the cost of about $50 for the game and $20 for the dance pad. They sell it for playstation 2 and Xbox. I have told numerous people at my school and they all went out and bought it. Within the last 7 weeks i lost 30lbs just by playing it for 45min a day and eating healthy. If you get a chance, definately try this out!
