CNN PRODUCER NOTE mysqlscott says his New Years resolution in 2012 was to run 500 miles because he was tired of not being physically fit and gaining weight along his midsection. He started using RunKeeper, a fitness application that tracks its user's running progress. 'I am the type who craves detailed feedback and data to measure progress and stay motivated, and RunKeeper gives me all the details I could ever want to track my goals and progress,' he says. With an office job and three kids he says it is easy to get tired and lose track of time, but with RunKeeper he makes exercise a part of his lifestyle. 'Before getting fit I was always tired, ate too much junk food and was really falling into a bad lifestyle routine and generally grumpy and unhappy. I now work hard to keep active, am excited about my weekly running miles, weight loss, energy and health eating,' he says.
