Part of a team of six PCYC lifters coached by Max O'Toole, Tiarna Davis, of Newstead, competed in the teenage 52 kilogram class and squatted 90kg, bench-pressed 48kg and dead-lifted 100kg - all world record lifts as was her total weight of 230kg. Longford's Jacob Oakenfull was the other most successful lifter competing in the junior 125kg class.

His world records were for his squat of 283kg and his total weight of 748kg.

"Tiarna had lots of PBs and did very well," O'Toole said.

"Jacob also got personal bests in his other lifts and both were very exciting to watch for us as Tasmanians."

Their PCYC teammates also performed well winning medals in their categories.

Norwood's Dylan Oakenfull won his 140kg teenage class with personal bests in all his lifts in only his third competition.

Westbury's Johnny Riley took out his 82.5kg junior division with personal bests in his deadlift and squat.

Launceston's Luke Mayne, competing in the 140kg junior class, was first in the benchpress-only competition with a lift of 215kg.

Launceston's Troy Thomas finished second in the 100kg junior class behind teammate Riley. "It was a great competition with lots of international lifters of enormous size who lifted enormous weights and lots of female lifters who were all excellent and big crowds on both days," O'Toole said.

One of the most exciting of the international lifters was a 25-year- old American Richard Hawthorne who weighed in at 60kg.

"He lifted 255kg in the squat, 150kg in the benchpress and 272.5kg in the dead-lift - an amazing total of over three times his body weight as a raw lifter," O'Toole said.
