After Warrior more of these bodybuilding bodies came to wrestling.
Although Hulk did have a great physique even earlier.
But likes as Dave Boy Smith and the Warlord come to mind.
Texas Tornado was always a poor mans Warrior to me 🙂
Even Curt Hennig would've been labeled bodybuilder in the early 80's.
I think the phenomenon attracted more "physique guys" to get involved, and others who were already in the business got more and bigger pushes.
Vince McMahon Jr. was always fond of big guys in his promotion early on, but there seemed to be a shift from "any" size to "quality" size after the success of WrestleMania. That's when he started "rewarding" the guys who were bodybuilder-big, and it prompted many wrestlers to get on
(more) gear.
Side note about Hogan: He testified in court to using lots of Deca and Test in his early days. After the steroid trial in the 90's, he came off a lot of that and slimmed down. Apparently, WCW didn't have the same drug-testing policy, because Hogan re-gained a lot of size after going there; this time with previously unseen
(for him) conditioning.
