You point about what happens when people go to Westside is not accurate. You are right that lifters are very good before they get there, but that is often after years and years of training. Louie then takes them and adds hudreds of lbs to their totals in relatively short order. You can think what you want, but to add hundreds of lbs to elite totals time after time is something very unique and powerful.
Doesn't matter where AJ Roberts or Dave Hoff train. They'll be great no matter what. I do agree that Westside adds great numbers, but to say it's the program is just very short-sighted. The atmosphere and expectations play a much bigger role than the program. If the program was that great, everyone who trains as hard as AJ or Hoff would be as strong as them without the group.
