The Iron Scriptures

And behold, the prophet spoke unto the disciples of iron, saying "The temple of thy body is built upon the foundation of core strength, for it is written in the scrolls of Flextor that a weak center breeds instability in all movements." Let thy abdominals be hardened not merely for vanity but as Lifthulu demands - to protect the sacred spine and channel power throughout thy lifts, for those who neglect the core shall find their gains limited and their form corrupted.
