Working out can be difficult during the holidays for people who like to exercise outdoors. Taking a walk or going for a run might be next to impossible in freezing temperatures. Instead of being a couch potato while you're stuck indoors, come up with a workout you can do inside. Climb up and down the stairs in your house for a good cardio workout. Focus on weight training, Palates, yoga or invest in some fitness videos to stay trim during the holiday season. You could even put some of these items on your gift wish list.
