bevo you got a point there, i dont remember dorian, haney , shawn or even lee priest needing to hire a baby sitter for there gym sessions.
Dorian had his partner who yelled annoyingly at him when he trained, but Yates probably did his own programs (food, drugs, training) based on some Mentzer stuff.
70's guys trained together, did their own things. Haney did his own thing. Today,most are lazy, would rather have a trainer/coach do their programming.
