Looking for a way to burn an extra few calories a day? How about a few ways to burn 100 or more without even thinking about it? Set you alarm 15 minutes early and stop hitting the snooze three times. Get up and go for a walk every morning before heading to work. After two or three weeks of the pre-work workout, begin jogging for two minute intervals. When you are at work, walk around when you are on the phone. Get off the subway or bus a few stops early and walk the rest of the way. And when you get home, take a bike ride with the kids or take the dog to the park for a brisk way.
