If you want to burn extra calories (and who doesn't?), start by making little tweaks that add up to big lifestyle changes. That's the idea behind fitness guru Bob Greene's new Small Change Movement
. Here are some of Bob's suggestions for burning about 100 calories in ways so subtle you'll barely notice—until you step on the scale.
Sitting while listening to music or talking on the phone (25 calories for 20 minutes).
You should also:
Practice the piano. This childhood hobby that you're always pledging to pick back up can help you burn 95 calories in 30 minutes.
Bonus tip: Buy sheet music of contemporary songs
you love so you can play backup to Adele and Rufus Wainwright. The more you throw yourself into "Someone Like You," the better.
Calorie counts are based on a 160-pound woman, using data from The Compendium of Physical Activities Tracking Guide from the Prevention Research Center at University of South Carolina’s School of Public Health.
