Most people love to do cardio but don't push it hard enough. You can do this workout either inside on a treadmill or outdoors.
When doing it on a treadmill do the following.
Warm up for about 2 minutes at a walk. The spend the next 20 minutes doing this.
1:30 at a normal pace (either fast walk or a slow jog)
:30 sprint as hard as you can go
For outdoors use telephone poles. Sprint one then walk one. For the sprint work as hard as you can. Really go out it.
Keep that up for 20 minutes then get off and go about the rest of your day. It's that easy.
Now I'm not saying it will feel easy while you do it. It's hard as heck. But it'll burn lots of fat and it's fast and to the point. Give it a try this Christmas. You'll be glad you did.
