I must be missing some context because it looked like the discussion was on bodybuilding physiques from the golden Era to mass monsters of today.Nah, i was talking about ahnold. Also seem to recall people in this thread (or an earlier version of this thread) commenting that the usual Men's Health workout programs were ahnold's programs, just a bit retooled, and if someone tried to follow them, they'd most likely end up overworking themselves.
But that was a while ago and i can't say precisely when, so it could be just the memory playing tricks on me and getting some old gymbro advice mixed up.
But as to your question, I'd give less credence to someone who made a training program when they're on gear. Some programs simply require too much volume. I'm reminded of the Bulgarian method which breaks a lot of people iirc. It was recently retooled by Greg nuckols and Omar isuf to benefit natural lifters. Most articles/programs on bb.com for example are geared towards enhanced lifters. I can't speak on Arnold's program, I know many naturals use it though.
