I was schooled by a few old timers, as a teenagers back in '88-'89. Also was loaned a stack of the original Iron Man magazines (when it was a smaller size), going back to the 50's. Iron Man mag was usually right on. Think some of that advise was worth it's weight in gold.
All kinds of theory's and ideas back then, which the BB'ing vet's like to share with anyone who would listen. All interesting stuff. Made some of my better gains when doing the original 20 rep Breathing Squat protocol. It was hell on earth at first (I though I was in good football shape when I started it...not so) , but after getting adjusted to it (body & mind) produced some outstanding results.
Some of the diet habits were also a bit off the wall. Blenders seemed to be very popular back than, with anything from raw eggs, liver, cottage cheese, honey, milk powder, peanut butter, dates,etc or whatever else that came to mind thrown in. A gallon of whole or raw milk (on a bulking workout) was usually standard: sip the milk slowly throughout the day. Never chug-a-lug it. Never the less, I hold great respect for those pioneers, back in the day. Good Luck.
