Does swinging count as exercise?

not the dance..but like on a swing set at a park.

I did a search and found one site that said it burned 33 calories in 30 minutes, but not sure how accurate that is.

Sneeks, to 3FC! I would add that anything you do is good for you but I doubt you could turn swinging into a cardio activity. this is one of my favorite website to calculat calories burned. Scroll to the bottom to put in your weight and duration.
