易筋经相传天竺和尚达摩为传真经，只身东来，一路扬经颂法，后落迹于少林寺。达摩内功深厚，在少林寺面壁禅坐九年，以致石壁都留下了他的身影。达摩会意后，留下两卷秘经，一为《洗髓经》，二是《易筋经》。《洗髓经》为内修之典，归慧可，未传于世。《易筋經》為外修之書，留於少林，“流傳至今”。

然而现古资料证明，《易筋經》，实为明末天台紫凝道人所创，原系道家导引之术，与佛教实无干系。

实际上，“易筋”之名出自道家文献，并非佛家所创的语汇。如有学者指出，在宋代张君房所撰的道教类书《云笈七签.延陵君修真大略》中已有“易髓”、“易筋”的说法，更早的还可以在魏晋时期出现的道家求仙小说《汉武帝内传》中找到渊源。

So why does this text have such an impact on martial arts fiction? The answer lies in its unique blend of Daoist principles and practical exercises designed to cultivate internal energy and strengthen one's body.

According to legend, practicing the Easy Muscle Transformation can lead to incredible physical feats, including being able to punch through stone walls or lift massive weights with ease. These claims may seem exaggerated, but they are rooted in ancient Chinese medical theories about how maintaining balance between yin and yang energies within our bodies can enhance our physical abilities.

In reality, however,
