What are some different ways to judge a fitness cometition among friends?

Started a club to help people get in shape. Within that group there will be sub groups. Each sub group competes against each other for a chance to win some money. Any ideas how to determine a winner beyond weight or bodyfat. Since some of the club members are not looking to lose any weight or bodyfat but gain muscle. But for some people losing body fat is their main goal. I want everyone to have a fair shot at the money. The idea is to get people exercising no matter what their goals are.
