MostFit Core Fitness Sledgehammer
You could slam an enormous truck tire with a sledgehammer repeatedly and call it a workout. Or you could ditch the tire and swap out the latter with a MostFit Core Fitness Sledgehammer. Available in two weights — 8 lbs and 12 lbs — the American-made sledgehammer boasts a solid urethane head at the end of a plastic-covered fiberglass handle. Slam it into the ground and it rebounds upon impact, so all you’ll need for a workout is a [very solid] concrete or asphalt floor or sidewalk.
