We've gotta admit: pounding the hell out of stuff with a giant hammer sounds like a great way to get a workout. The Rogue Sisu War Hammer offers you the ability to do just that, with an empty weight of 14 lbs., a removable back plate for adding/removing weight — up to 28 lbs. if you fill it with lead shot — and a 38-inch handle with a pass-through design to provide greater leverage and maximum durability. Oh, and "Sisu" is the Finnish word for stubborn determination, which you'll need to finish your workout after a few swings of this beast.
