Wow! I feel so dumb sometimes. I've just noticed in stick practice just how much working with the foot couple, the pelvic couple, and the cavities takes the "excess slack" out of the fascia "body suit." I was practicing chambering, strike, parry, and thrust, and I could feel just how much more connected the parry was when I forgot about my arms and just attended to the couples and cavities.
Doh!! Better late than never, I suppose. :-)
Up til now I've noticed it in "bitty" bits here and there in more localized areas of the body, but today it felt like my arms were actually attached.
(Which reminds me that I posted a couple of months ago about my arms feeling really detached from my torso.).
