he helped Dorian out a lot during his reign so he liked his physique.
he didnt help alot..he claimed to have helped dorian more than he actually did. (the belief helped mentzer to make more money tho)
when dorian started out he was inspired by mentzers theories and adopted some of them and added his own twist to the high intensity philosophy.
dorian trained with mentzer 3-4 times in cali back in 1992..
but mentzer never helped dorian as much as some people claim. dorian was always his own coach.
mentzer liked dorians mentality but he didnt like dorians phsyique that much..(specially not after 94 or so)
