Greetings..
Nicely articulated, Scott.. if i can add a couple of considerations.. look for natural movements in your intention, there is an abundance of power in natural motion (Ninjitsu players are very good at this).... contrived motions are contradictions requiring mental interference.. that is the "relaxed" appearance of high-level players, they rely on natural movement.. natural movement appears less threatening, the opponent doesn't recognize the threat as easily.. Scott's example of the "wave-like" motion is usually exaggerated early in the training, but becomes almost imperceptable.. as we approach coherence and mind/body unity the intention to result time is nearly simulatneous.. although we have discussed the connective tissue situation ad nauseum, it bears mention in this topic, and so, there it is....
Too often, there is confusion between relaxed and limp.. relaxed tension (Peng) is necessary.. Heavy-bag work affords us hours of deep introspection into bio-mechanics, power generation, and results.. Qi is like a highly refined fuel, for maximum results we need a well-tuned vehicle.. depending on mystical manifestations will you waiting and wanting.. refine and maintain (tune your body) with clarity and awareness of purpose, and be dedicated and diligent.. the results will be observable..
Be well..
