At the North Pole, Santa hardly stops moving. And moving counts as exercise. It does not matter how you move, as long as you do it. Exercise is good for pretty much every part of your body -- even your brain. It makes you less stressed and can put you in a good mood. No wonder Santa is so jolly. How can you move more during the day? Try taking your dog for a walk, riding your bike to your friend's house, or putting on some music and dancing.
