Having a hobby that gets you moving is a fun way to burn calories, but you don't have to be an Olympic athlete. Tending a garden or running around looking for sales can count too (let's face it, shopping is practically a sport). Do you have any hobbies that get you moving? Have you ever kept track of how many calories you burn while doing what you already enjoy? Have you considered a step-counter to record how much you move day-to-day? Are there any hobbies you'd like to try?
