2. Snowshoeing

You might look funny and fall on your face a couple of times, but balancing on snowshoes while trekking through the snow is a great way to fit in a workout and have fun at the same time. You can burn hundreds of calories in just an hour, while also working the muscles in your legs, butt and core. If you use poles for balance, you can also work your arms and chest.
