How many jumping jacks would you do for a cupcake? Watch these little kids earn their cupcakes by exercising!

If this video doesn't make you smile, I'm tempted to say you're dead inside, but that sounds mean so...I hope this makes you smile! I found it utterly adorable. For a Preschool Fitness Day, kids earned a free cupcake for doing some very enthusiastic jumping jacks. And jumping jacks are easier than kettlebells, right? It's by recent Cupcake Wars winners The Cake Mamas in Glendora, California, via their Facebook page, along with a few kid-themed cupcakes and some fun cake pops.
