the only difference between then and now is that they trained naturally for a lot longer before hitting the juice. Also the juice at the time didnt make their bodies balloons like nowadays stack. Aside from this, there s nothing much to learn it s a pretty blank interview and zane seems a bit full of himself. Most of his statements are pretty lame too. When he says everybody look the same today, well everybody looked the same in the past too, cause it s entirely defined by the drug stack of the time and the kind of training. Each era has its "typical" kind of results/ bodies.
I d also add there are nowadays tons of natural or guys on low amounts of juice who look like he did and even better . They re all over the internet. Tons of pictures of guys who train intensely natural or on low amounts of the same kind of juice he used and look as if not more impressive than he ever did.
The more i listen to these old farts the more i realize they have pretty much nothing to say or teach you cant learn by yourself especially in this day and age of the internet.
