My cousin did this with her work. She started before Christmas, the person who lost the most weight during a certain amount of time got $500, second place received $300 and 3rd $200. She got 2nd place. She thought once the contest was over she'd slump back in to old habits but she hasn't. She excercises every morning and swims twice a week. She has lost close to 40lbs, she looks great. I told her I need some of her motivation!
