I just uploaded my commentary on Arnold Schwarzenegger’s book. No, I didn’t buy it, but got it from my local library, that bastion of socialism where everybody pays for it even though not everyone uses it!
He does admit to steroid use in the book. (A prior supervisor of mine, a triathlete, knew him from her childhood. Her father was a bodybuilder who hung out with Arnie. She remembers the giant horse-size needles.) He mentions tanning as an element important for a bodybuilding competition. He does not mention plastic surgery, heel lifts, or hair dye, since those are not particularly manly.
