kickboxing...

we started with a pile of empty boxes...

found a good spot for them on the walkway...

built a pretty awesome tower...

then gave it a good swift kick...

when that didn't work, used our hands to knock it down...

which worked quite nicely...

admired the results...

then busily moved the boxes around...

here, there, and everywhere...

and just kept running back for more.

it eventually turned into just kicking the boxes as hard as we could all around the yard.

boy, did that feel good.

too good to take pictures, in fact.

give it a try :)
