If Shane can do 237.5 after 8 years of training with a late start then someone brought up through a system, like the Chinese or former Bulgarian systems, could certainly do 250.
Mike, I talked with Nikolov today about the changes after Abadjiev. You are right, the two lifters at the Juniors in Minsk would not have been doing pulls 2 days before a contest under Abadjiev. Two days before the meet they would have worked up to level of their first attempts in both snatch & c&j, then somewhat lighter on the last day before. He says Abadjiev gradually over the years eliminated most of the supplementary exercises, but pulls never were eliminated entirely. For example, someone who had more trouble with racking the bar might work on pulls and less on front squats. Power cleans also continued to be used in training. But, of course, the real emphasis was on the two lifts themselves, and very often they would work up to max levels several times during the week, each time much as if they were in a contest. Nikolov thinks that the real difference was that after Abadjiev’s departure there just wasn’t the discipline, and often the lifters simply didn’t train as hard, wanted to rely more on doping. But just as elsewhere I am sure there were some who trained hard, some not so hard. Probably in the old days those who didn't train so hard didn't stick around very long. I wonder how many kids today in the West _would_ be willing to live the Spartan lifestyle that characterized their weightlifting camps.
