I have yet to see anyone who has used qi to overcome brute force.
I have never seen "Qi" overcoming brute force either; I had NEVER claim that in any of my posts.
But aren't you saying that "如用現代的觀點,那不能出力的原因不是「內氣」不通,
而是肌肉群處在它們不能作功的狀態,所以無法發力:" which means there is an underlying physiological reason behind Nei Qi?
Nei Qi is just a MODEL to describe certain observable phenomenon. The exact underlying physiology/physics? No body knows for sure yet. It is not about whether you believe in it or not. Whether you call it "banana" or "Xiang Jiao" it is still a fruit.
