4KG Steel Maces or 4KG Cast Iron Mace Bells are constructed from precision-balanced, hand-sculpted cast iron, and offer long-lasting durability with a competitive price. Steel Macebell is one of the earliest pieces of Strength Training tools and is getting more and more popular by the market. With the majority of the mace weight in the head, swinging the mace challenges the user`s stabilizers surrounding the shoulder joint, to build a strong core.
