I understand that I'm just asking if you think you are getting increase IR mm activation with balance bad, ie is that your goal or is it try to get everything working at one time
(erectors , TVA, Abds) ? Just picking your brain , I guess I have a little different thought process. When you put some one on a unstable surface unless they are a dancer they have to worry more about balancing then the movement at hand. So I guess What I'm asking are you trying to get the IR's activated / stronger or work on something else?
