I Became a Saint Through Bodybuilding

With a mortal body, he tempers himself like iron until he becomes a saint. Relying on neither spiritual energy, cultivation arts, nor miraculous inheritances, the protagonist uses only the equipment found in a modern gym, scientific training principles, and the extreme discipline of physical training to break through the constraints of cultivation in a fantasy world and forge a unique path to sainthood through pure strength. He breaks the traditional cultivation system: while every other path under heaven draws on the power of the world, I rely on sinew, bone, and flesh. With mortal strength, I overpower divine arts; with my body, I hold the heavens at bay.
