hmmm if It really burns 100 calories.do this 5 times a day and burn 500 calories. There are 5 commercial breaks in a 1 hour tv episode. Burn 500 calories while watching your favorite show. Now, that sounds like a plan!
NO EXCUSES! Home workout [Note to self: add 1 min plank to rotation and instead of burpees do mountain climbers and/or spiderman crawls). No excuses. Even if the day is hectic at least do this exercise at home
