Dorian probably trained harder and "smarter" somehow then all of them now. But also took it's toll. 6 sandows in what....8 years as a competitor. Probably could have lasted a few more years more going a lil' softer than he did. Sure, Branch trains hard but look how he fucked up his physique and the time it took him to get back on track. He has the density but fuck, training the way he does certainly won't help him get better symmetry and proportions.
Training like Dorian and Ronnie=torn tri, bi, lat, effed up quads, messed up back.
Levrone, heavy benching=torn pec
Levrone, heavy back exercise before Olympia=torn lat and tri
Flex Wheeler, who apparently trained heavy prior to winning his pro card (he trianed with Chris Cormier who was said to "lift the gym")=torn bi and pec tear.
Lee Haney,trained to stimulate the muscle= no real injuries that I know of, correct me if I am wrong
Same for Shawn Ray
Fux, Flex photo shot with heavy weights=infamous pic of a man buried under weight, and torn quads
Derek Farnsworth, 4'11 man who squats 800 pounds=weight that will make him shorter and shorter over the yrs.
