Hey, this sounds like fun. I wonder how many calories are burned by doing 200 jumping jacks. . .

Okay, I almost died doing that! How out of shape am I?! I had to keep taking breaks. In the middle of it all, I found out that I'm an Auntie again. Another nephew, boys outnumber us in my family big time.

You can calculate it based on time and your weight here:

It looks like for me, I'd burn:

# Minutes # Calories
1 9
5 44
10 88
20 176
30 263
40 351
50 439
60 (1 Hour) 527

Now to see how long it takes me to do 200 jumping jacks.

Oh my. That is SO much harder than I thought it would be! I am breathing so hard right now, and I only did 100. I will have to try to do the other ones later tonight. Geez!

Jen415. im with ya on the crunches, i cant do anything that involves jumping!

Holy, for me that burns 13 cal per minute. If only I could do 270 minutes of them, that's how much I have to do to lose 1 pound.
Hmm... I didn't time it though. I kept having to take breaks. Boy did those jugs of mine bounce. I can call them that as I'm breastfeeding
Hope saying that doesn't get me in trouble, I've heard there are some touchy subjects that get kicked off this site. I not really worried though.

I did it today. It was pretty tough, but I added it onto the end of my workout. I'm glad I did!!

Did my 200 before work this morning. I think I'm actually a little sore in my arms from yesterday's????

Good Morning
I did 30 JJ and thought I'd best do crunches before my breasts hit the floor!
