Since we all could use a little motivation to get us to exercise especially in Winter, why not bring a little friendly competition into the mix? Challenge a fitness buddy to do 100 miles of exercise in eight weeks. That works out to be 12.5 miles per week, which is totally doable if you exercise 4–5 times a week, and put in three miles each time.

Work out together or apart, just get those miles logged! Don't have to limit the competition to just running. Walking, cycling, swimming, or using exercise machines like the Elliptical or rowing machine count, too. You can keep track of your miles per day and agree on a date to reach the 100 mile goal. Also decide on a way to celebrate. Maybe you treat each other to a massage or manicure — something that motivates you to keep racking up those miles.

Fit's Tips: If you have an iPod nano and the Nike+ Sports Kit, you can go on Nikeplus.com and challenge a friend for 100 miles. After every workout you complete, just plug the nano into your computer and your data gets uploaded and stored on the website. You can check each other's progress and even send each other messages. When you reach your goal, you even get a little award that goes in your "trophy case."
