There is nothing on this planet that is as motivating for the average person as money. According to the theories developed by behavioral economists, if you tie cash incentives to ordinary and seemingly mundane activities people’s motivation actually rises up significantly. People get more inspired to do things out of fear of losing money rather than hoping to win money.
After fully understanding this concept two Harvard graduates named Yifan Zhang and Geoff Oberhofer developed a new and innovative iPhone application that makes you want to go to the gym and exercise. Their app is called GymPact and it currently serves over 40,000 gyms across the U.S.
The app works by making you pay money when you decide to slack off and skip your previously scheduled gym visit. The amount of money that is pooled up from the slackers is then divided between those who did work out on a regular basis. The company takes a percentage of the money lost by the non-exercisers as profits. Killing two birds with one stone, you could use this system to both get fit and earn some extra cash at the same time.
