The day belonged to Mirabai and Gururaj.
The royal family described the games historic as this year's Commonwealth competitions have an equal representation of Women and Men for the first time in a major world sporting event.
Chanu Saikhom of India won the gold medal, Marie Ranaivosoa of Mauritius got the silver and Dinusha Gomes of Sri Lanka claimed the bronze.
FIRST GOLD: Competing in the bright morning sun, Duffy cruised to victory by 43 seconds over Jessica Learmonth and had time to grab a Bermuda flag as she completed the sprint distance. Another successful lift of 107 kg consolidated her position at the top.
So while Poojary clinched the silver, the likes of Muhammad Azroy Hazalwafie Izhar Ahmad of Malaysia won the gold, while Sri Lanka's Chaturanga Lakmal Jayasooriya - who won the Silver ahead of Poojary in the Commonwealth Championships past year - settled with a bronze.
Ahmed, meanwhile, bettered his compatriot Hamizan Amirul Ibrahim's snatch record of 116kg, created in 2010 Delhi Commonwealth Games.
He cleared 144 kg in the clean and jerk which his personal best.
India showed their class in badminton on day one under the leadership of Saina Nehwal and K Srikanth, racing to an unassailable lead and handing out 5-0 thrashings each to both Pakistan and Sri Lanka. He managed 110 kg in the snatch and 134 kg in clean and jerk.
India had its chances to sew up the match but somehow failed to convert the good passes.
But Saurav Ghosal's 2-3 defeat to Jamaica's Chris Binnie came as a massive shocker even though Harinder Pal Sandhu and Vikram Malhotra won their respective opening matches. "I still enjoy wrestling, I still love the sport a lot. But still I am happy", said the diminutive lifter from Karnataka. I had a big role to play. "It was too heavy for me", he further added. There were two 3-0 wins for the men against Trinidad & Tobago & Ireland.
At 26-years, Gururaja - a relatively old debutant at the Commonwealth Games - had a late start to his weightlifting career.
Sisters Bronte and Cate Campbell, Emma McKeon and Shayna Jack set a world record 3 minutes, 30.05 seconds in the 4x100-meter women's freestyle relay, lowing the mark the Australians set at the 2016 Olympics.
