No, I’m not talking about the chemical spray used for self defense. I’m talking about an old fashioned warriors mace like I am holding. Not only can it be used for self defense, but you can get a great workout with one, and in a pinch it would be a great child motivator (who needs time outs) No, I haven’t gone off the deep end. It’s actually a really great tool to help you get a full body workout in a minimum amount of time and space. The video I made below gives a good introduction to the many wonders of the mace.
