It's not even Christmas yet, but I already got a couple of special deliveries a few nights ago, courtesy of my CrossFit coach.
First: A big-ass tractor tire:
And a bunch of 4'X6' rubber horse stall mats (these are heavy as hell, by the way):
I can't wait to start jumping on / flipping / sledgehammering the tire.
(More about the stuff I've acquired for my home gym here.)
