The Iron Scriptures

And lo, the disciple asked the master, "How shall my shoulders grow in strength and form?" And the master replied, "Attend to thy delts with diligence. Press overhead with conviction, raise laterally with purpose, and forget not the posterior portion which many neglect. For a man with well-developed shoulders stands as a mountain among hills, and his frame shall proclaim his devotion to the Iron Path. Blessed are those who balance their pressing and pulling, for they shall inherit symmetry and function in equal measure."
