Here’s a good example of a bodybuilding training routine: https://thinksteroids.com/community/threads/first-bodybuildi...
That said, I’m also curious what GP was referring to, specifically. Was he saying like “don’t do dumbbell curls”?
Competitive bodybuilding however is a totally different thing (very different lifts- mostly light weight, very high rep), and I think the extreme diet and drugs alone takes a toll on your body regardless of the workouts.
IMO, those are classic powerlifting exercises. From what I can tell, the pro body builders typically do a lot more machine work and other isolated movements because it has a better stimulus:fatigue ratio than large compound movements.
I competed in powerlifting in my 20s; my life revolved around squat/bench/deadlift. I enjoyed it, but yeah, he's right: training like that is very specific, like anything else, I suppose. I could squat, bench and deadlift a ton, but literally anyone could beat me walking up the stairs, or even arm-wrestling. The first time I tried CrossFit, it nearly killed me. And yeah, powerlifting tore my body to shit. Back then, the only time I wasn't in pain, was when I was lifting.
They are also classic bodybuilding exercises.
* Weightlifting (Clean & Jerk, Snatch)
* Powerlifting (Squat, Bench, Deadlift, Maybe Bentover Row)
* Bodybuilding (High volume isolation exercises)
