An average person doing jumping jacks at moderate intensity can burn 100 calories by performing approximately 1,000 full jumping jacks. One jumping jack takes less than a second to perform. The more a person weighs, the more quickly they will burn calories.
According to AngryTrainerFitness.com, "Don't expect to be able to do jumping jacks for ten minutes nonstop." Jumping jacks are best as a quick way to warm up and increase blood flow. However, the monotony of jumping for an extended period of time is challenging. Mix jumping jacks with other quick workout moves, such as air squats, to maximize results and prevent boredom.
