筋道不舒長,欲伸而筋不能伸*
When the fascia channels are constrained and short, one cannot stretch at will

Fascias by essence being passive tissues, the main issue is, of course, how to make them participate as much as possible in motion and power generation. Stretching and particular body angles are the main way some old practices used to have the student understand how to generate power using fascia elasticity as it has been described in the section Fascia Elasticity. Still, to further understand how this works, it may be interesting to use an old martial art method, studying animals.
Being passive structures transmitting mechanical tensions, one cannot use fascias directly but only through muscles, body angles and sometimes gravity or any other outside force. If in the posts The Bow, Cornerstone of Elasticity and The Cross and the Six Directions, the principles behind the angle issue has been described in details, the muscle issue can be further explored. The first issue resides in the kind of muscles one is looking for to enhance the use of facia elasticity, mainly the difference between tender and hard muscles. Furthermore, building from the example of the hanging gibbon against working on a chin bar, one can also explore the difference in motion between the use of muscle contraction and fascia elasticity.
