I recently did some CrossFit after quite a few months of not tackling these workout circuits, so they started me out with this workout called "Nancy" and I was completely GASSED afterwards.  My muscles had atrophied from the skills required to do the workout in a POWERFUL way. We deal with degenerative issues across all areas of our life if we don't exercise and use the capacity that we have been given.  The body is the structure that allows you to carry out what it is that you dream and see.  If you want to have incredible relationships, WATER THEM!  What do I mean by that? You need to use what you got and put into your relationships or your body will dry up.
