Having worked in the state prison system for 10yrs I've seen some of the biggest, strongest humans ever.
These guys would come out at 6:30am before morning chow in sub zero Jan weather, toss on 315 after brushing off the snow and proceed to "warm up" doing 15-20reps for a few sets. Then after chow do nothing but heavy ass bench or long sets of pull ups...not the kind one would normally do or see but wide armed all the way to the neck, pause then keep on for 20-30reps.
We used to joke saying they could eat nothing but stated baked bread, peanut butter and rocks and still grow like beasts. Yet only a select few would ever do legs. That was the 1st thing we'd hit when mixing it up with them...no pins no wins.
Don't know how true it is but I've heard because of the fact "Hebrews" produce the least amount of myoststin out of all other ethnicities they grow muscle faster and thicker... Anyone know if this is true or not?
