people in the IS crowd have vilified the soft tissue a bit i think. but the soft tissue is part of the body and is part of how the body works (i.e. that's the nature of the human structure).
so what if there's some tension in the soft tissue during effort? what matters is the balance between tension and relaxation. too much tension and you become stiff and unable to change. too loose and you have no power. that's tai chi. the balance between yin and yang, not only yang.
So what's the general idea of how it works, Ashe?
