In 1972, the 'second' AAU World Championships were held, this time over two days – 10 and 11 November. This time there were 8 lifters from Great Britain (two of whom, Ron Collins and John Pegler, did stints as Referees), six Canadians, two Puerto Ricans, three Zambians, and one from the West Indies. With 67 lifters in all, the other 47 were Americans. Lifts were measured in pounds, the bench press was the first lift, and there were still no suits, power belts, or knee wraps. New Zealand's Precious McKenzie won his 'second' world title totalling 550 kg at 56kg. Mike Shaw 'lost' his world title, which he had won the previous year, to American Jack Keammerer. Ron Collins made up for his 'bomb' on the bench in 1971 and stormed to the 75 kg title. Pacifico won against another American, Mel Hennessey, at 110 kg, both with enormous benches of 260 kg and 255 kg. At Super (over 110 kg) John Kuc beat Jim Williams with an incredible 2,350 lbs total (raw). Kuc squatting 905 lbs for a record squat and attempting a 397½ (875 lbs) deadlift again, and Williams benching a massive 307½ (675 lbs) – the greatest bench press ever at the time, before just missing with 317½ (700 lbs). Jon Cole, the Super heavyweight winner of the US Senior Championships 1972 and holder of the greatest total at that time with 1,075 kg (2,370 lbs), didn't show up to take on Kuc.
