Matt’s been forcing inviting us to do “sled-dragging” with him lately.  It involves filling that tire with lots of weights and then pulling it as fast as possible… over and over again for a certain amount of time.  Fun times, indeed.  It’s pretty brutal, and we are definitely the crazy neighbors on the block now, but it’s also pretty fun and certainly healthy.  He’s a firm believer in sprinting and has wanted to create a prowler or sled at home for some time now, so he’s happy.  Now I better get off the computer and do some working out before he catches me here!
