It's too easy to get out of shape in the winter, unless you choose to make fitness a priority. If you want to burn calories and stay slim this winter, here is a tip that may sound like a joke at first: play video games! It sounds silly, but we're not talking about your traditional video games. Games such as Dance Central or Wii Fit can actually burn calories. How much exercise can you really get playing these games? A recent study found that the average heart rate during an active game session was similar to the heart rate during strength training.
Another, more expensive option for staying in shape this winter is to buy a treadmill. You can find some cheaper ones if you look in the classifieds, or online at sites like Craigslist and eBay. Just make sure you test it out before you buy. It's a good idea to put it in front of a TV so you'll be more entertained during your workout sessions.
