Ronnie was better on the more basic lifts . Dorian was more mahcine like overall.
Hard to say who really did train "harder", both were classic hardcore , no frills style of trainers.
I have both the Coleman "That's Incredible " and Yates " Blood and Guts training videos.
Ronnies 2 resp with 800 along with all the incredible barbell lifting is incredible.
But for pure training value I would say Yates was more effective.
Most normal guys would get injured or NOT grow as much traing like Ronnie did with the loose form and heavy basic moves. Yates style is something ANYONE could use and make gains.
Arnold had the best overall form however , as seen in Pumping Iron.

Ronnie would have broke down Leroy and Yates in their primes, was very durable. Yates was breaking down by his 5th Olympia while Ronnie broke down almost 2-3 yrs after his retirement.
No way those two deal with his lifts 5 weeks out from the Olympia, let alone offseason, just no way. They would have been tearing shit left and right.
Also, I don't believe Ronnie did ego lifts like Branch and JOJ. He just did it for the love and brute strength.
