Onnit Steel Mace

Onnit’s supreme quality Steel Mace is one of the most effective ways to train and condition your whole body while mimicking real world movement. Originally developed by the ancient Persian warrior elite, the Gada (heavy mace) style of training was directly applicable to real world combat and wrestling applications. In modern days the mace quickly gained popularity as a distinct improvement over the well documented sledgehammer / tire training, but the applications go far beyond that important motion.

With an extremely disproportionate weight displacement many normal movements prove quite challenging and beneficial to the myriad stabilizer muscles surrounding our joints and primary power centers. The mace is one of the most effective ways to build core and rotational strength, and is a steel testament to one’s desire to take fitness back to its primal roots.

Onnit’s Steel Mace is comprised of a single piece of welded steel and coated with a chip-resistant black finish. The flat spot on the head allows for simple upright storage, and since it is made of solid steel, it is virtually indestructible.

What size should I get?

The Steel Mace is a very challenging and exciting piece of equipment to master. Many of the exercises are best perfected at a lower weight, so if you are planning to utilize the full gamut of possibilities we recommend starting with a light weight (10lbs or 15lbs) and working up. The great thing about the mace is that if you want to increase the resistance you can simply slide your hand closer to the end of the handle.
