But if those Christmas cookies and cups of eggnog are starting to catch up with you, don’t worry, there are plenty of fun winter weather activities to offset those extra servings. The best news is that exercising in the cold air ups your calorie burn, so get off your couch and get moving—you’ll be back in shape in no time.
