Nice try but try again , what " New Level " of back development did Ronnie have that Yates didn't years eariler?
We're not talking about great arm development , or taper , or lumpiness lol what " New Level " of development did Ronnie have that Dorian did not?
define "new development".
if you are speaking about developing muscles in the back in the back to a level that had not yet been seen, well, than ronnie had "new development" for the reasons I listed.
if you are trying to say that Dorian developed muscles in the back that had not been seen up until that point, well, then you are wrong.
I would say that the last "new development' in terms of muscle was the appearence of striated glutes, which until Rich Gaspari, had not been seen on a bodybuilding stage.
