Doing a set of 100 jumping jacks will burn approximately 20 calories. For maximum weight loss, consider adding multiple 100 jumping jack sets throughout the day to help maximize the number of calories burned each day.
Jumping jacks are an especially great exercise for those people who spend lots of hours at work sitting down at a desk. It can be difficult for people who are required to sit for work to get the 30 minutes of activity that the United States Surgeon General recommends each day. Jumping jacks can be done at work or at a home office. Try to squeeze in 100 jumping jacks every 2 hours or at regular breaks throughout the day.
Another variation on jumping jacks is to jump with alternate feet as though jumping rope. This is another way to wake up the body and get blood pumping. Jumping jacks combined with squats, push-ups, shoulder presses, burpees and other calisthenics are great exercises to get the heart rate up in between longer workouts. In fact, these workouts can be combined to create a kind of boot camp circuit workout that is high-intensity, leading to more weight loss as well as increased cardiovascular levels, as noted by WebMD.
