Steve Reeves was one of the first names to come to my mind as well. He had an amazing physique, although I don’t think he carried as much mass as some of the latter individuals (Park, Pearl etc). That’s not to say he was doing anything inherently wrong, as you’ll always find people who can grow off anything they do, and he was someone who actually did think about what he was doing.
Reeves did do full body sessions early on, actually I’m fairly certain most trainers did full body back then because that’s just what the thinking was. Hit everything, rest, come back and do it again. It may have been the same exact session 3x/week, but as Ryno pointed out, these guys were training for hours every session. Additionally, they weren’t doing many different movements for each body part, so while the development was certainly good (and anyone today would be lucky to sport a physique like Reeves in his prime!), it wasn’t the level of development that you would see a lot more of once the idea of splitting things up and hitting something else while you were recovering from the previous session became the norm.
Have there been any high level competitors who have employed this approach? I won’t pretend to know it all, but if I were a betting man, I’d say that there haven’t been any in the last few decades. This sport is about standing on the shoulders of those who came before you. That means that we’d be foolish to ignore any of the approaches or techniques that have already been tested, figured out, and adopted by so many successful trainers and bodybuilders. This is especially important in our current era of armchair experts, keyboard warriors, and wanna be fitness authors/coaches trying to make their names by challenging what’s been working for countless people with much better results than they’ve ever achieved -lol.
When I started coaching Rob Stein, his time was very constrained. He had a full time job teaching, and a part time job doing his composition. So he was able to dedicate time for a 2 way split. I don’t recall all the details at the moment (it was a few years back), but considering all the variables and constraints we had to deal with, he did pretty damn amazing (2nd place at a very tough contest). The following year, with more time on his hands, we both knew we had to rachett things up, and that meant a better split that was more conducive to making the kind of progress we needed. Long story short, he came in bigger, tighter, nabbed a pro card, and walked away with an amazing physique, AND a ton of knowledge about how his body worked (we discovered a lot of patterns in terms of water retention, cardio types etc). Now, I can brag about Rob for a whole thread, but the point is, when presented with the option for a better split, volume, etc etc, we both knew that was the better option. Success leaves clues, and anyone would be foolish to ignore that truth.
