Casey and Jones were both smokers. I doubt Casey in his prime could run around a block without gassing. All this stuff about being offered a NFL contract sounds like bs to me. I'm sure he would rather work in Arthur Jones factory for chump change instead of a NFL contract.
did you ever hear about Casey's leg workout under AJ's supervision?
it went like this... leg press til failure 750x25 and then IMMEDIATELY leg ext til failure 250x22 and then IMMEDIATELY after those 2 exercises, both taken til complete and utter failure, he did FULL BARBELLL SQUATS til failure 505x12
so are you now actually gonna try and tell me that someone who could do this feat is not fit as fuck?
that's not just strength, that is strength plus an incredible level of fitness
