A post ago I mentioned about Alan Calvert and Bulletin 48 about posture. Continuous mild exertion in the maintenance of posture grows your body, asserts Calvert.

Calvert, a trainer of men, a man of deep knowledge of the iron game, writes with the authority that only experience can bestow. I’ve been playing with the methods described in bulletin 48 and while I can’t say I’ve fully got it, I feel the difference, and it feels good.

Check out the video to learn more about Bulletin 48 and how your posture can be impacted and your size and strength improved.
