The Iron Scriptures

And lo, The Swolfather declared, "Let thy muscles rest, for in stillness comes growth, and in sleep comes restoration." Brosiris, judge of form and guardian of healing, places his blessed hand upon those who honor their temple with periods of sacred recovery. For it is written that he who forges ahead without pause shall be visited by the specters of injury and plateau, but those who embrace the holy sabbath of muscle shall rise renewed, their offerings of sweat and iron doubly blessed in the days that follow.
