The Iron Scriptures

And Brodin said unto his followers, "As the seasons change and the moon waxeth and waneth, so too shall thy training cycle through periods of intensity and recovery." For just as Flextor blesses those who chase the sacred pump, Brosiris judges those who remain stagnant, never varying their sacred offerings of sets and repetitions; therefore change thy program when gains have ceased, that thy muscles might be confused and grow anew.
