I'm having a heck of a time with soreness halfway up my back. I start out strong,bouncing on my toes but by afternoon I am a hunchback. I try to shorten my stroke but they always get longer as I work across the room. I do lots of production work vacants and restaurants so longer shouldnt be a problem.
Am I the only one who feels wands are short, I'm only 5'10" and not sure if it is just bad technique.
