Hi, I've always been fascinated by maces. I'm very beginner and turning 57 (!) in a month. I know you've said in other videos that one can progress by holding closer to the end of the mace, but does my height of 5'4" preclude a quality workout with a longer, 10-pound mace? Or do the 10-pound maces ever come in the 30" length, do you know? Thank you!
