The country's top weightlifters dominated the first day of the National Games' weightlifting competition at Hevindo Sports Hall in Balikpapan, East Kalimantan, on Monday.
World junior champion and 2007 Southeast Asian (SEA) Games gold medalist Eko Yuli Irawan of East Kalimantan won the gold medal in the men's 56 kilograms.
Finishing second was another national team member, Jadi Setiadi of Lampung, while Jambi lifter Rusdi came third.
Eko's East Kalimantan teammate Triyatno, also a 2007 SEA Games champion, won the men's 62 kilograms, outpowering Eko Santoso of Central Java and Cacarno of West Java.
Both Eko Yuli Irawan and Triyatno are expected to compete in the Olympic Games next month in Beijing.
"Our weightlifting squad's target is to win at least three gold in the (National) Games," East Kalimantan weightlifting coach Lukman told The Jakarta Post.
"Our weightlifters already delivered two golds. Hopefully, we can earn another gold from Edy Kurniawan in the men's 69 kilograms tomorrow," Lukman said of Edy, another gold medalist from last year's SEA Games.
2004 Athens Olympics silver medalist Lisa Rumbewas of Papua once again dominated the women's 53 kilograms.
Lisa lifted a combined 203 kilograms to take the gold, easily beating silver medalist Sri Indriani of Lampung with 174 kilos and bronze medalist Isauna of West Kalimantan (159 kilos).
In the women's 48 kilograms, national team member Citra Febrianti of Lampung brought home gold, leaving the silver and bronze medals to Masitoh of West Java and Marlin Suabay of Papua, respectively.
The domination of national squad members, however, failed to impress Indonesia's Olympic Games weightlifting coach, Mulyana.
"Eko's showing today was below his best. That's not a good sign for his preparations for the Olympic Games," Mulyana said.
"He could go home (from Beijing) empty-handed if he does not improve his performance," he said, adding that the other Olympians also needed to step up their performances.
