A very, very good book. (Movie "Lincoln" was based off of this book.)
Bodybuilding related because Lincoln could hold an axe with his one out stretched arm with just a finger and thumb for seven minutes. No soldier around the ranks (he was inspecting at the time) could come close.
Also, after he was shot, they took his shirt off, (and this is in the book) .. they couldn't believe how big his arms were.
A true Getbigger, to be sure.
