The holidays can be stressful enough without adding the burden of trying to lose weight. But if you know you're going to want to whip yourself into shape come January, you can at least help yourself out by not putting on any new pounds during the holiday season. While that may seem like a tall order, you might already be doing more than you think. A lot of everyday activities help boost your calorie burn. See how much you can burn without even trying:

• Sitting in a meeting or class: 65 calories/hour
• Driving to your grandma’s house: 75 calories/hour
• Shoveling snow: 353 calories/hour
• Playing pool: 93 calories/hour
• Grocery shopping: 130 calories/hour
• Cooking dinner: 93 calories/hour
• Scrubbing floors: 197 calories/hour

• Baking Christmas cookies: 106 calories/hour
• Chopping wood: 282 calories/hour
