As delicious as chocolate may be, the days leading up to December 25th don't need to involve copious amounts of sugar. Dare to be active this holiday season. We put together a fitness advent calendar with 25 workout 'dares'. See if you can commit to our daily challenges - each day of the month will correspond to the number of reps you need to perform, or the duration of a particular exercise. While you're following our fitness advent calendar, be sure to use the #DaringDecember tag in all of your posts. This will help you to connect with other people around the world who are just as awesome as we think you are.
