This retarded bullshit has to stop. Alwyn Cosgrove always talks about how the fitness industry acts like a pendulumn, and always swings to the extremes. Should isolation movements be the focus of your routine? No. Should you not do them at all? No. Find me one big fucking strong guys who doesn't do some curls and other stuff at the end of workouts. Ed Coan? Curls and shoulder raises every upper body workout. Zydrunas Savickas? Yeah, he does curls too. Evegny Chigishev is one of the best oly lifters in the world, and he does curls and bench. Read the logs here. Read the logs on EliteFTS. Read the logs on Marunde Muscle. Find me one motherfucker worth his salt that doesn't find isolation useful from time to time. Grip work? Well fuck, that's isolation. Don't do any fucking grip work!
