It's that time of the year. And you want to get your Crossfit on but you don't want to shell out a couple hundred dollars per month to do it. Enter the Core Hammer by Most Fit.
You don't even need the tractor tire for this one. Swing it wherever you want (ground, driveway or cement) to get that full body workout. (Caveat Emptor: I'd probably shy away from swing it anywhere inside the house unelss of course it's a industrial style loft with river views.)
