I estimated about twenty minutes at average speed and taking into account that you slow down as you do more and get tired.
doing 50 jumping jacks will burn 5 calories
The amount of calories you will burn doing jump jacks varies based on your size and the intensity at which you are jumping. An average 150 pound person jumping 60 minutes will burn 306 calories.
improved answer: it depends on your weight, age etc. 1 minute of jumping jacks burns 8 calories for an average 150 pound person (according to sparkpeople.com). So about 10-15 mins of jumping will burn 100 calories. Depending on how vigorous of course.
If you are female with a height of 5'2" weighing 110 pounds, you would have to do jumping jacks continuously for approximately 36 minutes in order to burn 240 calories. Source: http://caloriecount.about.com/cc/activity/16.html
okay, that's like me saying "how much cheese in one basket?" does it make sense to you? no... Caitlin&Justin
50,0000
Maybe like a few. that would be like, oh I don't know, 7 or 8. That is really not alot!!!
That's all down to what you are eating. If your eating habits are about right, and assuming jumping jacks are about as much work as jogging, then you'd need about 40 hours of jumping jacks to work off 5 pounds.
It takes about six or seven jumping jacks for a 150 pound person to burn one calorie. Going off of the "3500 calorie rule" (which is now known to be completely false because weight loss varies depending on metabolism and body composition among other things), this means that that person would have to do about 21,000 jumping jacks at minimum to lose one pound of weight. Of course, this isn't a hard and fast rule for everyone. A 200 pound person, for example, may burn a calorie every 5 jumping jacks, meaning only 17,500 jumping jacks are needed. A 125 pound person might need to do 8 or 9 jumping jacks to burn a calorie, meaning they might need as many as 32,500 jumping jacks to burn 3500 calories. And losing a pound of fat isn't as simple as burning 3500 calories, unfortunately. Everyone deals with a calorie deficit differently. And the closer someone is to a sort of weight equilibrium, the less weight they will lose. That is simply a matter of diet and metabolism. But, if you are looking for a short answer, an average person may need at least 20,000 jumping jacks before they lose a pound of fat.
Just jump nonstop......that'll work.... You're gonna have to do more then jumping jacks to lose 50 pounds in a month. Also, you have to have surgery to lose that much in a month. If you have a realistic goal like 15 pounds then eat healthier and exercise.
the thing is jumping beans dont do jumping jacks and the reason they jump is that inside the bean there is a silkworm and soon the silkworm will stop moving so the bean will stop moving it is not dead its just dormant, and eventually a cacoon will come out of the bean and in a matter of seconds a moth will come out of the cacoon.
well, to burn 100 calories you would have to do around 700 jumping jacks. It also depeinds on your level of fitness, body weight, and speed. So, let's say around 15 calories.
