Kicking up the Intensity

If you increase the intensity of your jumping jacks workout, youll burn more calories. For example, a person weighing 150 pounds will burn about 274 calories in a 30 minute bout of jumping jacks when theyre done at a vigorous intensity. This means theyll burn about 9.1 calories per minute. A 200 pound person will burn about 366 calories in 30 minutes when jumping at a vigorous intensity. This equates to 12.2 calories per minute.
