winter

If you're more of a gym person than an outdoor workout type, your only real exposure to the elements fortunately only lasts for the forty-three seconds it takes to walk from your car to the gym entrance. But, there will soon be days when the roads are not plowed, the gym is closed, and taking your routine outside is just plain crazy. It's good to know that even on such crummy days, there are ways to burn some calories without ever leaving the house.
