hmmm......do this 5 times a day and burn 500 calories. 10 times = 1,000 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!
eaten-away: More jumpin jacks fo me I keep seeing this, and the math makes no sense. If every two jumping jacks burn 1 calorie, than 1000 jumping jacks would burn 500 calories. Not 3500. Not a pound of weight. However, jumping jacks are still awesome. Easy to do and get your heart rate up quickly. I do 100-300 a day, spread throughout the day.
