Burned 800 calories with Jumping Jacks?

I weigh 215lbs and apparently someone my size burns 4 calories a jumping jack. So I did 200 jumping jacks meaning I burned 800 calories? Sounds too good to be true. Can anyone verify?

Well if you did a jumping jack every 2 seconds that would be 400 seconds. Divided by 60 that's 6.6 minutes. I DOUBT that you burned that much in 6.6 minutes.

Heck if you did TABATA PROTOCOL (a very high intensity program of 4 minutes) you might burn 150 calories total. And that's GASPING for air after about 1 minute into it.

That's outrageous! I would have to run about 2 hours straight to burn that many calories!!! (I guess I gotta start doing some jumping jacks.) But seriously, a single jumping jack is a very simple movement. It doesn't seem worthy of 4 calories...I think the trainer guy is right.

Sounds too good to be true.

Then it probably is. How I wish we can burn that much in a span of minutes but unfortunately not. Heck even a 30 minute workout on elliptical couldn't do that either.
